IRACING BETA INTERFACE:

New Application Framework

– The iRacing BETA Interface now utilizes a brand new application framework.
– – This system will make future development for our team much easier, and streamline the connectivity between the iRacing BETA Interface and the actual iRacing Simulator itself.
– – This framework should greatly enhance the speed and usability of the iRacing BETA Interface as a whole, cutting down on loading times, increasing click responsiveness, and providing better usability feedback.
– – With this new framework, the iRacing BETA Interface will now live in its own application window, even while the Simulator is running.
– – The iRacing BETA Interface will no longer be viewable through VR headsets, and will be displayed on a traditional monitor screen.
– – – The Simulation will still launch in a VR headset if selected.
– – – If desired, you may also utilize third-party software, such as Virtual Desktop, in order to run the iRacing BETA Interface in a VR headset.
– – Once you’ve finished downloading and installing the 2019 Season 3 Release update, you will be asked if you would like to create a desktop shortcut to the iRacing BETA Interface, even if you disabled this question in the past. If you allow it, this will create a brand new desktop shortcut that will launch the new iRacing BETA Interface with the new application framework.
– – The new desktop shortcut points at a different .exe file (iRacingUI.exe, located in the “ui” folder of your installation directory).
– – – If you opt to create this new desktop shortcut, the updater will also delete any old desktop shortcuts iRacing had created to the former iRacing BETA Interface. However, the updater will not delete any shortcuts you may have made (or edited), so be sure to replace any of those yourself.
– – You can access the updated iRacing BETA Interface via the new desktop shortcut, the Membersite website banner, or launching the iRacingUI.exe file.

Create a Race – Wizard

– A brand new iRacing UI Wizard has been summoned to manage the Create a Race process for Hosted Sessions!
– – The Wizard is a new method and layout for creating Hosted Sessions.
– – This method allows a user to configure Hosted Sessions in a step-by-step interface or consolidate all steps into a single scrollable interface. Users can also jump back and forth between the two views, and also between steps as desired.
– – – Click on any step in the top navigation bar to jump to that step.
– – – To view all steps into a single consolidated list, use the “All Steps” button near the bottom-left corner.
– – Users may also perform the following actions using the dropdown menu in the bottom-left corner:
– – – Reset all fields
– – – Load Last Session info
– – – Load Autosaved Sessions
– – The Wizard features all new “compact” car and track selection interfaces.
– – The Wizard is still studying to make the following features a reality, and will be coming soon:
– – – The ability to directly upload a Fixed Setup for the Session.
– – – The ability to select a Session Administrator.
– – – The ability to restrict a Session to specific Clubs and/or Leagues.

IRACING SIMULATION

Updater

– The update process for this release, particularly for the iRacing BETA Interface, requires a few specific steps in order for you to be able to utilize the iRacing BETA Interface. The very short version of these instructions is to utilize the classic Membersite for your initial download of the update.
– – Please also refer to the very first section above, entitle “New Application Framework”, for more details.
– – You may also want to review the special post, “2019 Season 3 – iRacing BETA Interface Update Steps”, found here: https://members.iracing.com/jforum/posts/list/3650535.page

– When the iRacing Updater finishes and is checking to see if a user has the necessary system components installed, it will now check Windows 7 systems for the “D3DCompiler_47.dll” file, and it will direct a user to Microsoft’s website to obtain the appropriate Windows Update if it is missing.

Cars

– Suspension damper (shock) velocity has been capped to help to prevent zippies (unrealistic rapid accelerations, usually due to a collision, that often send the car flying into the air).

Car Classes

– All Car Class groups have been updated to account for the new, updated, and retired vehicle changes with this season release.

– A new Car Class, NASCAR Cup – 2018, has been added.
– – This Car Class includes the NASCAR Cup Chevrolet SS and the NASCAR Cup Ford Fusion.

Opponent Cars

– Opponent cars should now align better with where their driver actually is.

Vehicle Setups

– All previous and current vehicle setup versions should now be usable within each NASCAR vehicle class.

Green-White-Checkered Flags

– The ability to ensure a Green-White-Checkered finish to Race Sessions that run with full-course cautions has been added.
– – With this feature enabled, if a full-course caution begins under the green flag (not white or checkered), the race will be extended to ensure that when the caution period ends, drivers get the green flag, then get the white (1 lap to go) flag on the next lap after that.
– – A Session can have either an unlimited number of Green-White-Checkered Cautions (G/W/C) at the end, or a limited number. System and spotter messages will inform a driver of whether or not a caution period is the final caution period during which a G/W/C finish will be attempted.
– – In a Session with Full Course Cautions OFF, a race admin is also able to throw a caution that will utilize Green-White-Checkered Flags.
– – This feature is available when creating Hosted Sessions on both the iRacing BETA Interface and the classic Membersite.

Tires

– Low speed handling (<25mph) of cars with deep and/or soft tire treads has been improved.

Dynamic Track

– The total amount of solar energy allowed to penetrate through clouds and adjust the track surface temperature has been increased. This will cause clouds to have a reduced effect on temperature changes.

– The Track Conditions information on the Info tab of the Session screen has been updated to include all Sessions, and now uses the same Session names as the Race Details area.

Spotter

– A significant portion of the base spotter audio has been re-recorded for improved consistency and variety.

– A variety of new spotter calls have been added, including:
– – SPCC_GWC_EXTENDED = Lets you know whether this caution period will extend the race in order to end under the Green-White-Checkered Flag.
– – SPCC_GWC_FINAL = Lets you know that this is the final caution period that will extend the race in order to end under the Green-White-Checkered Flag.
– – SPCC_FUEL_1LAPS = Called when you only have one lap of fuel left.
– – SPCC_MINUTE & SPCC_SECOND = Called for labeling lap time lengths (minute & second).
– – SPCC_MINUTEPL & SPCC_SECONDPL = The plural forms of the above (minutes & seconds).
– – SPCC_1TOGREEN_RESTART & SPCC_GOGREEN_RESTART & SPCC_GREEN_RESTART & SPCC_NOGREEN_RESTART & SPCC_PACEIN_RESTART = Optional spotter calls that are triggered during race restarts. If the flags are not filled in then iRacing will default to the non-restart variations of these spotter calls (i.e. SPCC_NOGREEN).

– The calls, ‘SPCC_1TOWIN’ (one lap to win) or ‘SPCC_1TOGO’ (one lap to go), will now always be called when applicable for time-based races.

– Our online guide for how to develop new spotter packs has been updated.
– – See this thread to learn more: https://members.iracing.com/jforum/posts/list/3646900.page

– A great many improvements have been made to our spotter calls to aid in translation.
– – All existing spotter packages will need to be updated to fit the new form!
– – – You can read about these changes here: https://members.iracing.com/jforum/posts/list/100/1938030.page#11513531

– Translation Improvements:
– – Support has been added for more plural forms of spotter messages.
– – – We now optionally support zero, one, two or many items. This requires a renaming of the messages, previously the default form was singular, and we marked the plural case with a PL at the end. Now the default form is the plural (many) case and we mark the 0, 1, 2 cases with a _P0, _P1, or _P2 at the end of the message. If your language does not use a particular plural form you can NULL out both the string and wave file and we will ignore that form. For example, in English, we only need the _P1 and default forms to handle 1 and many.
– – All multi-part messages no longer share any message id’s.
– – – This allows you more freedom to rearrange the sentences as needed or NULL out a part you do not need. For example, the messages SPCC_PACE_PASS <num> SPCC_PACE_PASS_PT2 says ‘pass the’ <num> ‘car’ in English, but could be reorganized to say ‘pass car’ <num> NULL for another language.
– – Numbers now support a SPCC_Nx_EQ form that is called if the number is an exact match.
– – – For example, this allows us to use two different forms of the word ‘one’, as in 1, 21, and 301.
– – Support for an optional call SPCC_DECIMAL has been added.
– – – When filled in, this message will be called at the end of a decimal number, used to say ‘decimal’ after reading a decimal number if that is what is expected in your language.
– – An optional call, SPCC_AND_TEN has been added that when filled in will reverse the tens and ones place.
– – – For example, the number 321 would be called out as SPCC_N300 + SPCC_N1 + SPCC_AND_TEN + SPCC_N20, to say ‘three hundred one and twenty’.

– Fixed an issue with the “fuel left” calls triggering when not needed.

Driver Swap

– Fixed an issue in a driver-swap session where the last-displayed driver’s name would be displayed in the Driver/Team area, in the lower-left of the Session screen, even when the selected car had no driver.

Flagman

– The start/finish flagman has been re-built from the ground-up, and should now fully animate to wave the appropriate colored flags at the appropriate times during events!

Driving Camera Adjustments

– A variety of new driving camera adjustment options have added to the Drive tab of the Options Screen!
– – Height of the driver can now be adjusted.
– – – This affects the user’s view height across all cars at the same time. The user can also tweak each car individually as needed via the camera tool. While driving, the user can adjust the height of the driver camera using the F9 Black Box, or using the “Ctrl+[” or “Ctrl+]” keys.
– – The value “VanishY” has been renamed to “Horizon Offset” to better reflect its purpose.
– – – A user can adjust this value to shift the horizon up and down on the display without changing the location of the camera. Ideally, the horizon would be set to the same height as the driver’s eye line, but a user may want to shift it up to get a better view of the dashboard. While driving, the user can adjust the height of the Horizon Offset using the F9 Black Box, or using the “Shift+[” or “Shift+]” keys.
– – Field of View (FOV) is now available for adjustment.
– – – This value was already, and remains, adjustable while driving with the F9 Black Box, or using the “[” and “]” keys. FOV adjusts how zoomed-in the view appears, much like using a zoom-lens on a camera. Ideally, this value would be set via the FOV calculator in the Graphics tab, but on a single monitor setup using a wider FOV may be necessary.
– – The “Roll Chassis” value lets a user blend the side-to-side motion of the driver’s head between staying level with the car’s chassis, or staying level with the world horizon when on a banked surface.
– – – A value of 100% indicates that the camera would be locked to the car chassis, and a value of 0% indicates that the camera would be locked to the horizon. The default value is 100%.
– – The “Pitch Chassis” value lets a user blend the up-and-down motion of the driver’s head between staying level with the car’s chassis, or staying level with the world horizon when climbing or descending a hill.
– – – A value of 100% indicates that the camera would be locked to the car chassis, and a value of 0% indicates that the camera would be locked to the horizon. The default value is 100%.
– – The “Neck Motion” value controls how much the neck of the driver moves to try and smooth the motion of the car chassis. This value can be reduced if a user has a motion platform or is using VR.
– – – The default value is 100% for optimal automatic smoothing.
– – The “Rotate With Velocity” value controls how much blending is done between the driver’s head aiming in the direction the car body is actually facing, or aiming in the direction in which the car body is actually moving. Increasing this value may help a driver detect an over-steer situation.
– – – A value of 100% indicates that the camera would be locked to the car body’s velocity vector, and a value of 0% indicates that the camera would be locked to the car body’s forward-facing vector. The default value is 0%.

Rendering

– Cockpit glass material has been improved to have a realistic maximum visible light transmission.

– The ambient occlusion of driver models inside of cars has been improved.

– World lighting has been adjusted to better account for the various densities of clouds.

– Trees now darken with overcast skies and cloud shadows.

– RTX2000 series graphics cards now use true Multi-View-Projection (MVP) rather than w-warping (which is used on GTX1000s), when three screen Simultaneous Multi-Projection (SMP) is activated. The MVP mode properly supports Y-offsets in the projections and also supports wider field of views (FOV) and side screen tilt angles than W-Warping.
– – The options screen now allows:
– – – Night Shadows may be enabled.
– – – Depth of Field may be enabled.
– – – Full side screen tilt angles larger than 45 degrees may be used (this angle is limited with W-Warping).
– – – Field-of-View (FOV) values larger than 145 degrees may be used (this angle is limited with W-Warping.

– Vehicle lightmaps have been adjusted to work better with bloom when using High Dynamic Range (HDR) Rendering.

– Night-time bloom thresholds have been adjusted, so objects should not bloom as easily at night.

– Particle detail levels of Medium and High are now functional with Simultaneous Multi-Projection (SMP) Rendering.

– Fixed several issues with the ambient occlusion effect in several shaders and improved its accuracy.

– Fixed an issue where Windows 10 display scaling above 100% would cause the Simulator’s window to be sized much larger than requested.

Headlights

– Headlight effectiveness and brightness has been improved, and many issues affecting the performance of headlights have been fixed. Specific updates include:
– – Headlight beam patterns are now always generated procedurally on the GPU and may now be affected when various individual lamps toggle due to damage (more to come in further updates), partial headlight flashing, or when some bulbs are otherwise turned off.
– – Car-to-car lighting from headlights and flashing has been improved.
– – Several rendering shaders and materials have been repaired that were causing headlights to be missing or to appear with incorrect intensities on many objects.
– – Headlight flashing has been improved on several of the higher-end road cars where partial sets of bulbs blink, and one can now always see their own headlights flash properly from in-car as well as from external views.

Dynamic Sky

– The appearance of a jagged edge at the horizon has been reduced.

Motion Blur

– A motion blur effect may now be enabled when viewing the environment from any camera.
– – This includes viewing as a driver, spotter, or spectator during an event, or when watching a Replay.
– – In the Graphics Options menu, a user may enable or disable motion blur, and select from three levels of motion blur that impact the intensity of the visual effect: Low, Medium, and High.
– – – This feature can significantly affect performance, especially on high resolution displays and multi-monitor setups.
– – – While motion blur is an expensive process when enabled, there is very little performance difference between the different amounts of motion blur.
– – While viewing a Replay, a user can enable motion blur for broadcast and/or driving cameras separately.
– – – A user may select to enable or disable motion blur for each camera type from the Replay Options menu.

Crowds

– Lighting effects on 2D grandstand crowd characters have been updated at all tracks.

Visual Effects

– – – Formula Renault 3.5
– – – Indycar Dallara – 2011
– – – McLaren MP4-30
– – – Pro Mazda
– – – Williams-Toyota FW31

– A reset button has been added to the Sound Volume sliders and the Driver View sliders that will return the sliders to the default value.

– Fixed an issue where car starter and ignition sounds for stockcars were not being universally applied to those cars with multiple motor types.
– – This should fix the issues with some stockcars starter and ignition audio sounded different at different tracks.

Controls

– Joystick button support has been increased from 64 buttons to 144 buttons. This will move the button address for the switch on newer Fanatec wheels; users will need to re-map any controls to the switch after this update.

Replay

– All cars have been updated so that the player car’s dashboard in old replays functions correctly.

– Fixed an issue where the right-front wheel of opponent Dirt Late Model cars appeared to have the wrong camber.
– – There will also be a very subtle change to the wheels of other opponent cars in replays.

Paint Kit

– A new sponsor, Sim-Lab, has been added.

– Several sponsors with multiple variations have been appended with numbers to differentiate them from each other.

Driving Aids

– For drivers with ability challenges, the driving line is rendered further into the darkness at night.
– – Please contact Customer Support for more information.

Race Admins

– The admin command “!trackstate <pct>” will now correctly ignore skipped Sessions when executing, and apply the requested setting to the next active Session in the event.

Lucas Oil Off Rroad Pro Trucks

– NEW TRUCKS!
– – The Lucas Oil Off Road Pro Trucks are now available for purchase in iRacing!
– – – This purchase includes TWO vehicles:
– – – – Lucas Oil Off Road Pro 2 Truck
– – – – Lucas Oil Off Road Pro 4 Truck
– – The Lucas Oil Off Road Pro Trucks are specially designed for Dirt Road racing.
– – – iRacing gives you the chance to drive the premier trucks in short course off-road racing! Pro 4 trucks are the biggest and baddest vehicles in the Lucas Oil Off Road Racing Series. These full-size, four-wheel drive race trucks can boast up to 900 horsepower and up to 20 inches of wheel travel. They’re designed to race in some of the most rugged conditions in motorsports, flying upwards of 100 feet in the air on massive jumps, carving through the dirt in high-speed corners, and taking heavy contact from other vehicles. One thing is for certain: they’re unlike any other vehicles in iRacing, except for maybe their Pro 2 counterparts!
– – – The Lucas Oil Off Road Racing Series is now available in iRacing, and the immensely popular Pro 2 truck class is along for the ride! Like their Pro 4 counterparts, Pro 2 trucks are absolute beasts under the hood, producing up to 900 horsepower. They’ve also got the same suspension travel as their slightly bigger brother. But with only two driven wheels and a slightly smaller wheelbase, they’re not just a perfect training ground for drivers who are looking to move up to Pro 4 someday, they’re a long-term home for some of the biggest names in the sport. All that adds up to some intense competition on race weekends, competition that you’ll get to experience firsthand with iRacing!

Mazda MX-5 Cup – 2015

– Exhaust crackles and ultra high frequency clatter sounds have been removed from the in-car engine sounds.

Modified – SK & NASCAR Whelen Tour Modified

– UPDATED VEHICLES!
– – We’ve completely rebuilt these cars from the ground up! Any user that already owned these vehicles receives these new versions free of charge. This update includes entirely new vehicle models, new textures, and a full re-evaluation of the vehicles’ physics and parameters.
– – The Modified – SK and the NASCAR Whelen Tour Modified are available as a unit; two cars for the price of one!
– – – Modified – SK: SK Modified racing is one of the most popular forms of oval track racing in certain parts of America, and iRacing’s updated SK Modified for 2019 brings these cars up to their latest and greatest spec. Many short track racers are happy to spend their entire careers racing these nimble, quick cars. But for drivers looking to further advance their careers, racing in large fields of high-powered, open wheeled cars provides an excellent learning experience.
– – – NASCAR Whelen Tour Modified: iRacing’s NASCAR Whelen Tour Modified is all new for 2019, sporting an updated body style that reflects the sport’s highest spec. Sporting a roof but no fenders, a Modified Stock Car – “Modified” for short – is a unique oval-track race car. And while today’s Modified is built from the ground up as a tube-frame chassis racecar and has significantly different configurations for paved or dirt tracks, the breed traces its lineage back to the very beginning of stock car racing. Light in weight and fitted with wider tires, a current Modified Stock Car is pure racer and much faster around a short oval paved track than one of NASCAR’s Sprint Cup cars.

NASCAR Gander Outdoors Chevrolet Silverado

– NEW TRUCK!
– – The NASCAR Gander Outdoors Chevrolet Silverado is now available for purchase in iRacing!
– – – Why race pick-up trucks? For starters, they’re arguably the most popular automotive vehicle in America, with upwards of 2 million new pickups sold every year in the United States. And they’re a blast to race, particularly the trucks of the NASCAR Gander Outdoors Truck Series. With 625 horsepower pushing their 3450 pounds around super speedways, ovals, short tracks and the occasional road course, NASCAR’s trucks are fun to watch and challenging to drive. No manufacturer has had more fun in the NASCAR Gander Outdoors Truck Series than Chevrolet, and its Silverado is all new and updated for iRacing in 2019. The Bow Tie contingent won the series’ first four manufacturer titles in 1995-98 and hasn’t looked back. While other manufacturers have come (and, in some cases, gone), Chevrolet has remained committed to the world’s fastest truck racing series as its teams and drivers keep racking-up race wins and series championships.

– A new Ilmore NTI spec engine and gears have been added, and aero has been adjusted slightly.

NASCAR Monster Energy Cup Chevrolet Camaro ZL1 – 2018

– Aero grills will now be adjusted based on the track type, per the 2019 NASCAR rule change.

– Per updated NASCAR Monster Energy Season rules, the right-hand speedway window is now mandatory at all tracks.

– Gear ratios and limits have been updated to match latest NASCAR specs.

– Fixed an issue that could lead to a pitboard logo being in the wrong location.

NASCAR Monster Energy Cup Ford Mustang

– NEW CAR!
– – The NASCAR Monster Energy Cup Ford Mustang is now available for purchase in iRacing!
– – – The Generation 6 Sprint Cup Car embodies NASCAR’s “Win on Sunday, Sell on Monday” heritage. After years of competing in other NASCAR levels, the Ford Mustang finally made its move to the NASCAR Cup Series for the first time in 2019, and found a home at the front of the pack right out of the gate. For more than 50 years, the Mustang has been the signature ride in the Ford stable of vehicles—a pony car that packs a punch and takes the fight to its rivals. The NASCAR Gen6 version of the car takes that fight to the next level, with a 3300 pound minimum total weight (with no less than 1600 pounds on the right side) along with carbon-fiber hoods and deck lids, and a 53″ wide rear spoiler.

– Any member who purchased the NASCAR Cup Ford Fusion after the 2017 Season 3 Release has been granted ownership of this vehicle for free.

NASCAR Monster Energy Cup Toyota Camry

– Aero grills will now be adjusted based on the track type, per the 2019 NASCAR rule change.

– Per updated NASCAR Monster Energy Season rules, the right-hand speedway window is now mandatory at all tracks.

– Gear ratios and limits have been updated to match latest NASCAR specs.

NASCAR Truck Series Chevrolet Silverado – 2013

– A new Ilmore NTI spec engine and gears have been added, and aero has been adjusted slightly.

Porsche 911 GT3 Cup Car (991)

– Fixed an issue with the rear camber on opponent cars.

Radical SR8

– Season setups have been updated.

Skip Barber Formula 2000

– Aerodynamic profile has been adjusted to better match real-world data.

– V7 tire adjustments, including:
– – Tire compound and carcass curvature have been adjusted.
– – Oversteer/Understeer balance and over-the-limit behavior have been improved.
– – Minimum tire pressure has been set to 25 psi for all four tires.
– – All four tires now also have tire warmers to bring them up to 130F.
– – – The primary change to the RT2000 is the improved aerodynamic forces, particularly side force and yaw moment. The rubber conditioning, which is the softening effect of simply working (stretching) the rubber repeatedly, is not quite correct yet, but the car is in a much better place than any previous build, so we wanted to share our current improvements. The tire pressure minimum is present because the handling is more predictable and better for new drivers with the higher pressures; without a minimum, nobody would run higher pressures. The tire warmers have been added to help offset some of the still unfinished conditioning effect.

– New gear shift sounds have been added.

TRACKS:

Atlanta Motor Speedway

Wild Horse Pass is also the only track on the LOORRS calendar to feature Pro 4 and Pro 2 trucks on the track at the same time, as the season-ending Lucas Oil Challenge Cup offers a five-figure grand prize to the fastest racer in short course.

Wild West Motorsports Park

– NEW TRACK!
– – Wild West Motorsports Park, a new Dirt Road track, is now available for purchase on iRacing!
– – – Sparks always fly in Sparks, Nevada when the Lucas Oil Off Road Racing Series makes its annual stop at Wild West Motorsports Park. With a stunning mountain backdrop, it’s one of the most visually unique tracks in short course, with a track layout to match. Wild West features four turns, two of which are proper hairpins, with four tabletop jumps, a massive drop-off jump after Turn 1, and a rhythm section before Turn 2 all designed to get the trucks into the air. Located just 10 minutes outside of Reno, it’s a great place to watch a race, and an even more exciting track to drive with iRacing’s new Pro 4 and Pro 2 builds!

– “Vehicle Damage” is now a toggleable option when creating Hosted Sessions and Test Sessions via the “Car Options” dropdown.
– – You can toggle damage ON (default) or OFF within the Car Options section of the Cars card.
– – With vehicle damage disabled, all vehicles in the session are indestructible, and will take no damage at all from any sources. Being invulnerable also means your vehicle performance will never be adjusted from collisions, such as changes in aerodynamics or vehicle weight that might normally result from an impact.
– – – For any and all iRacing Series (Ranked and Unranked), Practices, Qualifiers, Time Trials, Time Attack, and other non-user created racing events, vehicle damage will remain ON. This feature is designed for use in Hosted Sessions and Test Drive only.

– “Disable Decals & Numbers” is now a toggleable option when creating Hosted Sessions and Test Sessions via the “Car Options” dropdown.
– – With this option enabled, car numbers and car decals applied via the Paint Kit will not be displayed. Stockcar contingencies will also be removed.

– The Filtering and Sorting toolbar has been upgraded, separating filters into 3 different sections:
– – Sort = Orders the displayed information.
– – Categories = Filters by selected items.
– – Tags = Filters in ANY or ALL selected items.

– Race registration has been updated, and any errors that occur should be displayed more clearly.
– – These errors most often occur when trying to register for a Session for which you are already registered using a different car.

– For all Table Views, each column header can now be clicked to sort the table by the values of that column.
– – These sorts are saved when leaving the screen, or exiting the application.

– License restrictions for joining a Session no longer apply to Spectators.

– A new error modal window has been implemented that will catch some errors and display them.

iRacing BETA Interface – Current Series

– The Official Series section has been redesigned and optimized so that browsing the available Series is now faster and easier than ever before!
– – Users now have a page with all Current Series for the season displayed.
– – Clicking on any Series opens the Series modal window, which contains all available Sessions, a list of entries, schedule, and series information.
– – – Join an Official Session for the Series by selecting a Session to join.
– – – Click on “Entries” to see a list of all currently registered entrants, where you can spot, spectate, or join the session as a driver.
– – – “Schedule” and “Series Info” have all the details on the Series.
– – These changes result in dramatic performance improvements, and have been made to fix stuttering and responsiveness.

– Additional Current Series improvements include:
– – The “Search” function has been optimized.
– – Additional filtering options are now available at the top-right.
– – Tag filters can be set to match ALL selected Tags, or set to match ANY selected Tags in the dropdown menu.
– – – You can filter by Session details, such as if the Session is populated, has spectators, has friends, or has someone from your Watched Drivers list in the Session.
– – A Sessions filter has been added which matches Sessions that are currently “Open” for Registration as well as if a Session is “Ready Soon”. Additionally, Practice, Qualifier and Race Sessions can be filtered individually.
– – For Table View, reduced the number of columns for improved legibility.
– – For Table View, the column formerly known as “Promo” has been renamed “MPR” for clarity.

iRacing BETA Interface – User-Created Races

– The retrieval of Session data has been optimized, to get you the data you need faster and more efficiently.

– Selecting individual cars or entire car classes, results in a more consistent interface.

– For creating Hosted Sessions, “Fixed Setups” and “Car Classes” have been moved to the “Car Options” dropdown.

– Car abbreviations now appear in the Hosted Session modal Entry List.

– The Admin list is now alphabetized by driver.

– Filtering enhancements:
– – Individual car categories have been added to the Filter dropdown menu.
– – “Owned” and “Unowned” have been added as Tags for cars.

iRacing BETA Interface – Time of Day

– Time of Day and Date/Time selection has been reworked to use sliders instead of the calendar.
– – Time carry over has been removed in favor of simply not adding a time offset to the Session you are configuring.
– – The estimated start time of a Session with zero offset is displayed for reference purposes. Moving the slider past zero will recalculate the date based on the starting time and the offset that you choose.
– – Moving the slider bar will increase the offset of that Session and the starting time displayed will change based on the offset.
– – When the offset carries over into the next day, the date will be displayed for reference.

– Date formatting has been changed to be more internationally friendly.

iRacing BETA Interface – Fixed Issues

– Fixed an issue where Starred items would require a page refresh to be visible.

– Fixed an issue in Current Series and User-Created Races where the team label would highlight a team for which the user did not belong.

– Fixed an issue in the Open Practice tab where clicking the left “Register” button in a register dropdown menu registers the user as a Spectator instead of a Driver.

– Fixed an issue where clicking the Active Connections button would cause the iRacing BETA Interface to error out.

– Fixed an issue when selecting a track, sometimes only the first track config would be displayed as a choice.

– Fixed an issue where opening a Hosted Session modal, joining a League Session, or launching a Test Drive could cause the application to error, and/or enter an unstable mode.

iRacing Membersite – General

– As of this 2019 Season 2 deployment, iRacing no longer officially supports the Internet Explorer web browser.
– – For some web browser alternatives and more information on what this means, check out this post:
– – http://members.iracing.com/jforum/posts/list/0/3639224.page#11436534

iRacing Membersite – League Seasons

– League Season Driver and League Team Points standings can now be viewed as Overall (All Car Classes/All Cars), by Car Class, by Car, or by Car In Class.

– League Seasons can now be configured to drop races by specifying the number of races to count toward the standings. This can be set when creating or editing a season and a points system is selected.
– – Races are dropped for an individual when the number they have participated in surpasses the number to count toward the standings.
– – Races are ordered by the total points after adjustments with the highest scoring races being kept. Only adjustments made from the race results screen apply when determining if the race is to be dropped or kept.

– League Seasons can now be edited to change the season name, the points system, or number of races to count. Edit a League Season by selecting it and then using the new “Edit” button in the header.
– – Changes to the points system apply only to Sessions run AFTER the change was made.
– – If the points system is changed from “Custom” to something else, the original Custom points schedule will be deleted.

– League Season points adjustments can now only be made from the standings when viewing the overall (All Car Classes/All Cars) to be more clear that these adjustments count toward all of the standings, not only for a specific car class or car.

– League Season points adjustments made from the standings view are added in after races have been dropped for an individual.

– A new points system has been added as an option for League Seasons called “Dirt” which corresponds to USAC’s 2019 feature event points for non-Silver Crown races, as found in section 5.9 B. here: http://www.usacracing.com/assets/files/rules/2019/2019_part_4_Points.pdf

iRacing Membersite – League Heat Race Results

– For League Heat Races, the “Points” column now reflects the points earned in that segment.

– A new column called “Agg Points” has been added to the League Heat Race Results and reflects the total number of points earned from the first segment to the current segment.

iRacing Membersite – Spectator Sessions

– When Series Sessions that are available for spectating continue into the following race week, they will now be listed separately from the current race week sessions. Each list will be titled by the correct track name for the race week.

– Series Spectator Sessions are now first listed in order by license class (Rookie to Pro), then listed alphabetically within a license class.

– Hosted and League Spectator Sessions are now ordered by Session Name.

– Improved the performance of loading Spectator Sessions.

iRacing Downloader

– After applying the 2019 Season 2 update, the iRacing Downloader will now use IPv6 for its downloads if you have enabled iRacing to use this protocol, and you actually have IPv6 available. If a download attempt via IPv6 fails to connect, the downloader will retry using IPv4. If the download then succeeds using IPv4, the rest of your current download call will use IPv4.

Engine Model

– An engine cylinder compression torque model has been added to iRacing.
– – At low RPMs (below idle rpm), as the engine rotates it causes cycles of positive and negative torque to be generated as the individual pistons are being compressed then released. The amount of torque generated depends on the engine configuration parameters, such as compression ratio and number of cylinders. This allows the motor to stall out properly, and allows it to get “stuck” between cylinder compression torque peaks and not roll away if the car is in gear without the clutch being pressed. This also produces a jerky motion if the vehicle is rolling at very low rpm.
– – – The Anti-Stall Aid should be disabled in order to notice this in action, otherwise you will struggle to get the engine to go below idle.

– The Driving Shift Aid has been updated.
– – What was previously the “None” option was actually not none; it always left the Anti-Stall Clutch Aid on for you. With the updated engine stalling, we can finally let you turn the Anti-Stall Aid all the way off. Now, the “None” option really means no clutch aid at all. The “Anti-Stall Clutch” is now it’s own option. If you had “None” selected previously, you will now have the “Anti-Stall Clutch” selected to maintain the same level of behavior you had before.
– – If you choose “None,” it is very easy to stall the motor if you do not press the clutch in at the right moments. Watch out if you are in a car without a starter motor!
– – You will probably also want to turn the Auto-Starter Aid OFF and start the motor yourself.
– – When setting up a custom event, the Hardcore Level dropdown has a new entry for “Disallow all driving aids” that forces the Shift Aid to None.

– The engine startup sequence has been updated.
– – All cars now have engine ignition and starter noises.
– – The ignition/starter sequence remains a work in progress, and will be updated over time. Many cars will use a default sequence and share a generic set of sounds.
– – Cars with unique ignition/starter sounds are as follows:
– – – Audi Quattro GTO
– – – Audi R8 LMS GT3
– – – BMW M8 GTE
– – – BMW Z4 GT3
– – – Chevrolet Corvette C6.R GT1
– – – Chevrolet Corvette C7 Daytona Prototype
– – – Cadillac CTS-V Racecar
– – – Dallara DW12
– – – Dallara F3
– – – Dallara IR18
– – – Ferrari 488 GT3
– – – Ferrari 488 GTE
– – – Ford Falcon FG V8
– – – Ford GT
– – – Formula Renault 2.0
– – – Formula Renault 3.5
– – – Holden Commodore VF V8
– – – Indycar Dallara – 2011
– – – McLaren MP4-30
– – – Pro Mazda
– – – Skip Barber Formula 2000
– – – V8 Supercar Ford Falcon – 2012
– – – Williams-Toyota FW31

– Certain cars require the clutch pedal to be pressed (if the anti-stall clutch is not enabled) before the starter will operate:
– – Ford Mustang FR500S
– – Global Mazda MX-5 Cup
– – Mazda MX-5 Cup – 2015
– – Mazda MX-5 Roadster – 2015
– – Pontiac Solstice

– Certain cars have anti-stall clutch behavior built in to them, so even if you turn the Shift Aid to None, they will still have anti-stall.
– – Audi R18
– – Dallara DW12
– – Dallara IR18
– – McLaren MP4-30
– – Porsche 911 GT3 Cup Car (991)
– – Porsche 919 Hybrid
– – Williams-Toyota FW31

– Direct drive cars with Shift Aid set to None will still use Anti-Stall Clutch Aid when in the pit stall, or in a starting grid location to allow you to start the car up and get rolling – at which time the Anti-Stall Aid is disabled, so you can stall the car if you spin or stop.

– The auto-starter has been updated.
– – When getting in a car, the auto-starter will wait about half a second before trying to start the car, instead of the instant you hit the Drive button. If you have stalled the car on track, the auto-starter waits 2 seconds (while stopped, in Neutral, or pressing the clutch) before trying to start the car. Pressing the throttle makes the auto-starter fire more quickly.

Tire Model

– The new version 7 (V7) tire model has been introduced on the Skip Barber Formula 2000.
– – This model has significant improvements to both rubber compound modeling and tire carcass dynamics modeling, and the feedback has been very positive for the few vehicles we have been testing it on. Only the RT2000 has undergone enough testing to release with this build, but we hope to put this tire model on every vehicle soon.

– The allowable cold pressure range has been opened up to allow pressures that are, frankly, too low (14 psi) all the way up to too high (45 psi), but we feel it is important to allow you to push the boundaries so we can better find out if the tire is behaving reasonably. Running at too low a pressure can give you a very evil car. High speed corners and low tire pressures do not work well together. Which tire pressure is optimal will vary from track to track, and sometimes you may find compromising one part of a track is worth extra speed in other parts of that track. Also remember that average lap time is often more important than best lap time, so don’t forget to average in extra time caused by spins! In other words, if you’re having trouble racing on low pressures, try raising them.

League Racing

– League Season Heat Racing events can now earn Season points.
– – The Feature Race is allocated points based on the Season’s selected points system.
– – Qualifying, Heats, and Consolation Races are only allocated points if they are configured to do so and the points system is not “None”.
– – Points schedules and rules for Qualifying, Heats, and Consolation Races are based on USAC’s 2019 points schedules for non-Silver Crown races, as found in section 5.9 B. here: http://www.usacracing.com/assets/files/rules/2019/2019_part_4_Points.pdf
– – – Qualifying allocates points to the first six positions, 6 points for first, and decreasing by 1 for each subsequent position.
– – – Heats allocate points to the first eight positions, 8 points for first, and decreasing by 1 for each subsequent position. However, if Consolation Races are configured to receive points, then positions 5 through 8 only receive their points if they advanced directly to the Feature.
– – – Consolation Races allocate points to the first eight positions, 4 points for first and decreasing by 1 for each subsequent position with 4th through 8th receiving 1 point. However, participants earning Heat Race points will not also receive Consolation Race points.
– – – Stacked Consolation Races only allocate points for the final Consolation Race. Non-Stacked Consolation Race allocate points to each Consolation Race.
– – – – Custom points will be supported in a later release.

Heat Racing

– The method in which drivers are appended to the Feature Race’s starting grid when there is more than one non-stacked Consolation Race has been updated.
– – Previously, the specified number of drivers that advanced from a Consolation Race were appended to the Feature starting grid from the results of the first Consolation Race, then that number from the results of the second Consolation Race were added, etc.. Now, the winner of the first Consolation Race is added to the Feature grid, then the winner of the second Consolation Race is added, etc., followed by the 2nd place finisher of the first Consolation Race, then the 2nd place finisher of the second Consolation Race, etc., until the specified number of drivers have been taken from all of the Consolation Races.

Dynamic Track

– The system for calculating track temperature as reported to the user in the Info tab and telemetry has been improved.

Dirt Racing

– Reduction to tire grip on dirt surfaces as the hardpan is approached has been amplified.

Pit Stops

– Rule changes for GTE pit stops have been implemented.
– – Cars must now re-fuel first and may only change tires once re-fueling is complete. This takes into account the real-life WEC rules for the 2019/20 season.

Rendering

– Fixed an issue where teammates could not see the steering wheel rotate.

– A separate set of bloom post processing parameters have been added for night-mode.
– – This should help with the daytime sparkle issues, and improve bloom at nighttime.

High-Dynamic Range (HDR)

– This release includes a preliminary version of High Dynamic-Range (HDR) rendering. When it is enabled the Simulator uses HDR render targets for items such as mirrors, environment maps, main render targets, and even HDR display back buffers. Previously, very bright pixels would be clamped to “fit” into Standard Dynamic Range (SDR) formats. This clamping causes important information about the actual brightness of bright pixels to be lost and to be treated as less bright than they should be treated. HDR rendering allows the bright pixels to be rendered without loss of information, and used during many internal rendering steps, limiting the loss of brightness to only the final step of converting to the display. HDR rendering drastically improves the quality of rendering, and also provides for additional future effects (this is a very early version!). And, when coupled with an HDR display, it allows for an expanded color gamut and extremely bright sun and solar reflections to actually be displayed at higher intensity than the rest of the scene on the display. HDR does not require an HDR display to provide most of the visual benefits because many of the benefits occur before the conversion to the display, but HDR displays benefit the most.

– Support has been added for HDR displays, such as HDR10 televisions and monitors. The Simulator can now be configured to output HDR formats to an HDR display via an HDR10 frame buffer (10-bits per color channel instead of , or an HDR16F frame buffer (16-bit floats per color channel). When using HDR16F, the Simulator renders a special expanded color space (BT. 2020) using a special gamma (ST.2084). When rendering in HDR10 mode the Simulator just outputs the smaller color space BT.709 (HDTV color). However, Windows or the device driver may do conversions in either case, so you likely want to try both. When used in conjunction with HDR rendering, very bright sun and solar reflections can be displayed on screen, and the expanded color space looks incredible. You almost certainly need to be in full-screen modes when using these formats, especially HDR16F. If the Simulator leaves full screen, the colors may look blown out, and you may need to press Alt+Enter to get back into full-screen.

– To enable HDR rendering without an HDR display, all you need to do is check the “HDR rendering” checkbox on the Graphics Options screen, and restart the Simulator for it to take effect. When HDR rendering is checked, bloom is also checked, and cannot/should not be unchecked for best results. Enabling this option will use more video memory to store the extra large image formats, but higher end cards should have plenty of memory for this.

– To enable an HDR display, you will need to run the iRacing graphics auto-config and select an HDR10 or HDR16F mode from the resolution dialog, this will automatically force on HDR rendering and bloom. Try both HDR modes and select whichever works best for you. HDR10 uses slightly less memory, but HDR16F looks best in many cases due to the expanded color space. If the graphics auto-config does not present either of those modes, then you first need to setup your HDR display properly in Windows 10. HDR displays only work with Windows 10, and only when connected with higher-end display port 1.4 or HDMI 2.0 connections. And, in the Windows 10 display settings, the display first needs to be setup to be HDR. See the Windows 10 HDR settings in the Windows Settings -> Display Settings. If you cannot get Windows to first recognize the display as HDR and allow you to toggle it into HDR mode for gaming, you will be unable to get the Simulator to provide the HDR modes via DX11. Please note, you may need to also alter a setting inside the HDR display’s menus to enable HDR mode on the desired input, this is very common, before Windows will detect it as HDR capable. HDR display modes will not work on very old versions of Windows 10, and will not work at all on Windows 7.

Visual Effects

– Photographer spectators have been spotted using flash photography in the stands, and around the track!
– – These spectators will light-up their flashbulbs throughout a session, especially when there’s some serious action going on!

– Visual effects generated via PopcornFX should now better obey a users’ selected minimum detail level.

Virtual Reality

– A form of nVidia’s simultaneous multi-projection, named Single Pass Stereo (SPS), has been added to help optimize VR rendering. SPS allows the Simulator to render the scene for one eye, and then GPU, via shaders and SPS, create the image for the other eye, without the Simulator needing to submit the entire scene a second time. This reduces the CPU load of the rendering thread and increases the frame rate, especially for the largest and most complex scenes when the frame rate would be lowest.
– – SPS requires a supporting nVidia GPU with a newer device driver installed. GTX1000 and GTX2000 series GPUs, with device drivers after v390 support it. The option is called “SPS” on the Graphics Options screen, and it will be enabled by default if your device driver reports that your GPU supports it. If the SPS option is disabled in the Graphics Options screen, and you have a supported GPU, try a newer device driver.

– Fixed an issue when using VR where the mouse cursor could get stuck on a “curved screen mode” while using the iRacing BETA Interface, even when not on a curved screen.

Audio

– Ignition and starter sequences remain a work-in-progress, and will be updated over time.
– – Currently, many cars will use a default audio sequence and will share a generic set of sounds.
– – Cars with unique ignition and starter sounds are as follows:
– – – Audi Quattro GTO
– – – Audi R8 LMS GT3
– – – BMW M8 GTE
– – – BMW Z4 GT3
– – – Cadillac CTS-V Racecar
– – – Chevrolet Corvette C6.R GT1
– – – Chevrolet Corvette C7 Daytona Prototype
– – – Dallara DW12
– – – Dallara F3
– – – Dallara IR18
– – – Ferrari 488 GT3
– – – Ferrari 488 GTE
– – – Ford GT
– – – Ford Falcon FG V8
– – – Formula Renault 2.0
– – – Formula Renault 3.5
– – – Holden Commodore VF V8
– – – Indycar Dallara – 2011
– – – McLaren MP4-30
– – – Pro Mazda
– – – Skip Barber Formula 2000
– – – Williams-Toyota FW31

– All cars have had their engine load sounds modified to be more sensitive to subtle changes in throttle levels.

Driver

– Additional detailing has been added to the driver’s gloves.

Animated Pit Crew

– The animated pit crew will now look directly at your car as it approaches and leaves.

– The animated Indycar Pit Crew has been training all season, and is now 10% faster!

– The reflectivity of skin-tones in light has been reduced slightly.

– The air wrench hose movements have been smoothed a bit, and should appear less jaggy.

Pace Car

– A new pace car model, Porsche 911 GT3 Cup Car (991), has been added to the iRacing service!

– The default Road pace car is now the Porsche 911 GT3 Cup Car (991).

Replay

– When playing through a Session change, the system will look forward for data to prepare the replay world for the new session.
– – This fixes an issue on Session transitions where the track in replays could appear to have a stripe-pattern effect. This was being caused by data from the previous Session being used to create the track state, only then to have it overwritten in chunks with the new data.

Cameras

– While using the camera tool, blimp velocity may now be a negative number, so it can rotate in both directions.

Admin Commands

– A new Admin Command, “!trackstate”, has been added.
– – This command allows an Admin to view and change the track state of the NEXT Session.
– – – This is intended especially for dirt racing, to allow Admins to make on-the-fly changes to the track (like simulating some re-prep before the feature for example).

Telemetry

– A new telemetry variable, “PitsOpen” has been added. This variable is true if you are currently able to receive service in your pit.

CHANGE LOG:

UPDATES:

iRacing Beta Interface

– Performance Improvements
– – The iRacing Beta Interface has been disassembled and rebuilt from the ground up to improve overall performance and stability in all areas. This was a long-term project, and in the process we’ve made some dramatic improvements to the underlying structures that will provide immediately noticeable performance upgrades, and will make future development more water-tight.

– Dynamic Modal Menus
– – Modal Menus (A menu screen that appears over the iRacing Beta Interface, such as the Create a Race screen or the Downloader) now resize automatically to better utilize screen space.
– – Modal Menus now utilize a frame that includes action buttons at the bottom, while the content of the screen can scroll freely within the frame. This means that buttons like Cancel, Join, and Test Drive will always be displayed at the bottom of the modal menu window.

– Scaling Improvements
– – The options for scaling the iRacing Beta Interface can still be found in the Settings section, but now the UI Scaling is handled by the game engine, improving performance substantially.
– – The UI may now be scaled in 5% increments between 50% and 200%.

– Spotter Passwords
– – User-Created Races and Official Races now fully support spotter passwords.
– – – To view entries in Official Sessions, click the white icon indicating the amount of drivers registered for an event. Entries looking for a spotter are indicated by the headphone icon next to the “Register” button.

– Combined Sessions
– – Spectator Sessions are now part of all Official Sessions, and are displayed in the same list.

– Test Drive
– – You can now use a Test Drive button for any Hosted Session.

– Ultra HD Support
– – UHD monitors are now natively supported and no longer require a manual activation.

Downloads

– A new Content Delivery Network, Limelight, has been added as an option for our Members.
– – Some details on this enhancement can be found here: http://members.iracing.com/jforum/posts/list/3615303.page

– The “Total Download Size” on the Downloads web page has been updated to reflect the amount still to be downloaded, if a previous update attempt was partially downloaded.

– Fixed an issue on the download web page which could erroneously display a “not enough free space” error message.

Updater

– When the iRacing Updater shuts down, it will now generate car setup directories for all cars that you have installed. This should make managing and sharing vehicle setups easier.

Simulator

– We’ve added some preventative measures for some issues that may have caused stuttering for some members.

– Some of the third party software that the iRacing Simulator utilizes has been updated to a newer version. If you are running Windows 7, you must be running Service Pack 1 (SP1) or later in order to continue to use iRacing.

Connectivity

– The L/Q/S/P meters on the frame rate (FPS) display have been reorganized, and the ability to control them has been added to the in-Sim Options Menu.

– The meters are now broken up into 4 separate groups: Graphics, Network, System, and Steering/Force Feedback (which is only available while driving). They are still attached to the frame rate (FPS) display, and will all be hidden if you choose to hide the FPS display.
– – Each individual group can be disabled, shown graphically, or shown numerically, via selections in the lower-right area of the in-Sim Options Menu in the “On Screen Displays” section.

– Graphics Group:
– – Renderer (R)
– – – Graphically, this meter shows a 1-second running average of how much time it is taking for the iRacing graphics engine to build the set of commands that tell the graphics card how to draw each frame. An empty bar means it is taking 0 seconds, and full bar means it is taking 1 second. Like the CPU meter, a purple bar is shown beneath this one, and shows the 15-second running average.
– – – Numerically, this value is displayed in milliseconds, and only the 1-second running average is displayed.
– – Graphics (G)
– – – Graphically, this meter shows a 1-second running average of how much time it is taking your graphics card to draw the displayed frames. An empty bar means it is taking 0 seconds, and full bar means it is taking 1 second. Like the C and R meters, a purple bar is shown beneath this one, and shows the 15-second running average.
– – – Numerically, this value is displayed in milliseconds, and only the 1-second running average is displayed.

– Network Group:
– – Latency (L)
– – – Graphically, an empty bar is 0ms of round-trip network latency between your computer and the race server, while a full bar is 1000ms (one second) of round-trip latency.
– – – Numerically, this measurement is in Milliseconds.
– – Quality (Q)
– – – Graphically, the left-side meter measures the incoming network packet loss to the Simulation from the race server, and the right-side meter measures the incoming packet loss on the race server from your Simulation. Both meters measure only your connection to the race server, not your own, nor our race server’s overall internet connection packet loss. An empty meter is 0% packet loss, and a full meter is 50% packet loss.
– – – Numerically, this measurement is a percentage (100 means no packet loss, 0 means 100% packet loss).

– System Group:
– – CPU (C)
– – – The core of the Simulation runs 60 times per second (though some parts run at a higher rate). To keep-up with the simulated world, the Simulation must complete an “update” in less than 1/60th of a second, otherwise it will start to fall behind.
– – – Graphically, this meter shows a 1-second-long running average of the percentage of that 1/60th of a second the simulation is taking to “run the world”. An empty bar means 0% of that 1/60th of a second is being used, while a full bar means at least 100% is being used, but it could actually be “running long”. If the simulation keeps “running long”, it will begin to fall behind “real time”, leading to time Skew between your Simulation and the server. A purple bar is drawn beneath the normal CPU bar, and it shows a longer-term 15-second running average.
– – – Numerically, this measurement is a percentage of the allowed 1/60th of a second that the Simulation is using to update the world. Only the 1-second running average is displayed.
– – Skew (S)
– – – This meter measures the simulation-world time difference between your Simulation and the correct simulated-world time, as kept by the race server. While small flickers of Skew can appear due to “network jitter” (variations in the round-trip network Latency between your computer and the race server), significant amounts of Skew are almost always caused by your computer being unable to perform the calculations necessary to keep up with real time (see the CPU (C) meter discussion above). That is why this metric appears as part of the System group, instead of the Network meter group.
– – – Graphically, an empty bar means your simulation is in sync with the server. As the meter grows to the left from the center, your system is falling behind the server, and the bar will be full-left when the Sim is 1 second behind. As the meter grows to the right from the center, your system is getting ahead of the server, and the bar will be full-right when it is 1 second ahead.
– – – Numerically, this measurement is in seconds.
– – Paging (P)
– – – Modern computers have physical RAM (memory), but programs that run on them operate using a “virtual memory” address space. For a program to actually use the contents of a piece of its virtual memory, it must have actual physical RAM memory attached to it. Paging is the term that covers how the operating system manages the attachment of physical RAM memory to a program’s virtual memory addresses. When the OS must intervene in the virtual<->physical memory attachment of a 4K byte “page” of memory, that causes a “page fault”. “Hard” page faults are when the operating system must transfer data between physical RAM and your disk (or SSD). These are slow operations that can greatly impact the performance of your computer if they occur at a high rate.
– – – Graphically, hard page faults are shown in green or yellow, and the meter will be full-yellow at 30 hard page faults/second.
– – – Numerically, this measurement displays the number of hard page faults per second.

– Steering Group:
– – Force Feedback (F)
– – – This metric shows the torque from the steering column as a percentage, after the scaling from your force slider is applied. You want to keep the forces below 100% so that the wheel is not over-saturating, but still high enough that you are using the full range allowable from your wheel. You can make adjustments to your force levels while driving by using the F9 black box. Or you can drive a clean lap then hit the ‘auto’ button in the F9 box to let us find a reasonable estimate of how much force to send to the wheel.
– – – Graphically, red indicates you have 100% torque saturation, yellow indicates you have 85% to 99% torque saturation, and green indicates 84% or less torque saturation.
– – – Numerically, the value displayed is the percentage of torque saturation.

– If the Simulation determines that it seems to be having performance issues that are causing it to fall behind the race server, the FPS and other meter displays will be forced on, even if you currently have them hidden. Additionally, the System meters (C/S/P) will be forced to be displayed, even if you had marked that particular meter group as hidden. The labels of the meters that indicate the indicate the performance issue will be flashed. Currently only the C and S meters are analyzed for performance issues, and so only those meter’s labels will be flashed.

Driving Aids

– Fixed an issue where the pit lane exit blue line for “Pit Lane 0” at tracks with 2 pit lanes would show when in any pit lane, and the “Pit Lane 1” line would show when not in a pit lane. Now, the blue line will correctly show up for whatever pit lane you are in, and not show any if you are not in a pit lane.

Hybrid Power Units

– Removed an efficiency correction that was left in by mistake in the MGU-K deploy demand, and deploy cap calculations.

Dirt

– The shape of the water gradient on dirt ovals is now variable, and slightly more water will be lost in the process of wearing the track away. This will cause tracks to transition from the prepared state to hardpan a bit faster and less predictably, and create a slightly drier environment overall.

– Made the toughness of dirt and resulting grip more sensitive to water content.

– The lateral strength effect of the cushion dirt has been reduced slightly.

– Heat Races at Dirt Ovals will now initialize with more track wear, and the variance of that starting usage percentage has been increased.

– The track groove that forms during Dirt Oval races should now be displayed even with the Graphics Option “Render Dynamic Track Data” disabled.

Rallycross

– Body stiffness and damping of Rallycross cars has been reduced to help decrease visible body damage and improve car-to-car contact performance.

Opponent Cars

– Opponent vehicles on your machine should now have more accurate positioning measurements sent to it from the Race Server, including altitude, roll, pitch, and steering angle. This should make opponent vehicles appear to drive smoother while racing, and in Replays.

Garage

– Fixed an issue where some values were incorrectly flashing yellow.

Rendering

– Improved the dynamic level-of-detail (LOD) adjustment for cars and pit objects when too many are visible and too high LODs are being used all at once. The LODs are now based on actual object distance rather than view depth.

– Fixed an issue where the driver’s hands would disappear from your car when you were not the active driver.

Visual Effects

– Smoke effects now react to wind, lighting, shadow, and a visual turbulence effect has been added.

– Jet fly-overs have been adjusted.

Audio

– Backfires and gear shifting sounds for stockcars have been improved.

– Marble impacts, scrubs, and castoff sounds have been improved.

– Hit and scrape sounds for grounding impacts of vehicle undertrays on soft materials, such as tirewalls, rubber, and some chicane humps have been improved.

– Sawtooth curb sounds have been improved.

– Audio volumes have been re-balanced for all default iRacing camera sets.

Paint Kit

– The Craftsman logo has been added to the Paint Kit.

Force Feedback

– The Simulation will no longer attempt to dampen when the Force Feedback option “Dampen Oscillations” is checked. Instead, it will only reduce the force level. The dampen effect is not stable on all wheels. This should help reduce some wheel oscillations when the car is parked.

Telemetry

– New driver change telemetry variables have been added:
– – dcDashPage, dcPitSpeedLimiterToggle, dcDRSToggle, dcPushToPass, dcStarter, dcLowFuelAccept, dcHystBoostHold, dcFCYToggle

– New driver pit telemetry variables have been added:
– – dpFastRepair, dpFFlapSetting, dpFuelAddKg, dpFuelFill, dpFWingAngleOffset, dpFWingSetting, dpLFTireChange, dpLFTireColdPress, dpLRTireChange, dpLRTireColdPress, dpLTireChange, dpRFTireChange, dpRFTireColdPress, dpRRTireChange, dpRRTireColdPress, dpRTireChange, dpRWingAngleOffset, dpWinshieldTearoff, dpFUFangleIndex

– Driver pit telemetry variables “dpLrWedgeAdj” and “dpRrWedgeAdj” have been renamed to “dpLRWdgeAdj” and “dpRRWedgeAdj” to better match the rest of the driver pit telemetry variables.
