Pace Car
- A new pace car, Sedan, has been added to iRacing!
- - This pace car is a sedan-style vehicle, not manufactured by any of the known names in cars. Our secretly created sedan provides no brand favoritism while maintaining a stylish and professional look on the track!
- - The Sedan is now the default pace car for asphalt oval events.
- - The Sedan may be selected for use, like our existing pace cars, while creating Hosted Sessions at asphalt ovals.
Opponent Cars
- Fixed some issue with a small variety of opponent cars including:
- - Opponent cars were heavily striking curbs at Long Beach Street Circuit.
- - Some stockcars appeared to be floating slightly at oval tracks.
Dynamic Track
- Track surface dynamics have been updated to react more realistically with tires of different compounds, such that softer tires will tend to produce a thicker layer of rubber than harder tires.
- Added the ability for the server to begin transmitting dynamic track data for the next session to clients, which is designed to make session transitions more accurate, and avoid large visual changes in the first few moments of a new session.
Team Racing
- Fixed a bug that prevented Race Control from properly enforcing the driver-swap rule where all declared drivers must drive a fair share if the same member was declared as a driver for multiple teams.

Race Series
- For the IMSA Racing Series, all included cars now load into the event with some IMSA-specific modifications.
- - The following vehicles are effected, and ONLY effected during IMSA Racing Series events:
- - - BMW M4 GT3
- - - BMW M8 GTE
- - - Chevrolet Corvette C8.R GTE
- - - Dallara P217
- - - Ferrari 488 GTE
- - - Lamborghini Huracán GT3 EVO

- - These cars have white numbers in the number boards, and a rear number that can be color-changed in the paint shop.
- - Each car has Michelin tires except for the Lamborghini and the Ferrari, which have no tire branding.
- - Each car has IMSA leaderboards. These digital displays show the car’s position in its class. The digits on each display are the same color as it’s car class (red for GTLM, etc.).
- - For cars that have round position lights on the sides, they remain, but will not function by design.
New Damage Model
- The New Damage Model has been enabled on the following vehicles:
- - Dallara iR-01
- - Formula Renault 2.0
- - NASCAR Chevrolet Monte Carlo - 1987
- - NASCAR Ford Thunderbird - 1987
- - Street Stock
- The manner in which tires react to forces have been adjusted so they handle object impacts more consistently.
- - Tires handle forces from contact with anything other than the ground with a more simple algorithm that favors consistency. Forces acting on tires from objects will now match those seen by opponents for all drivers. This makes wheel damage consistent between player and opponent cars.
- - Tire impacts with a surface, such as the track, curbs, and off-road areas, will continue to use the original high-complexity tire force algorithm.
- - Wheel-on-wheel impacts should now damage both wheels appropriately, rather than one car seeming to always come out of the incident with more damage. In addition, these changes make future development easier as the forces involved are now much more consistent in repeat situations.
- The following parameters have been adjusted to improve the look and feel of crashes:
- - Reduced the torsion bar torque applied when either wheel has been removed.
- - Tire and rim colliders are now separate objects.
- - Wheel hyper-extensions have been further reduced with more accurate correction forces.
- A variety of properties were adjusted to improve the appearance of crashing opponent vehicles, including:
- - Smoothed the forces applied when a wheel reattaches to reduce jitteriness or spikes.
- - Reduced the likelihood of force application spikes from wall collisions.
- - Optimized visual averaging of wheel stability to reduce visual hopping.
- - Wheel tethers have been tightened slightly and force damping has been increased.
- Fixed the following incorrect behaviors and potential crash issues:
- - Fixed an issue where opponent car wheels would partially break but remain attached in the wrong position.
- - Fixed a Simulator crash issue that could occur when an opponent car with a detached wheel was reset to the pits.
- - Fixed a Simulator crash issue that could occur when a player car with lightly damaged wheels was reset to the pits.
Qualification Conduct Scrutiny System
- Some additional adjustments have been made for the Qualification Conduct Scrutiny System particularly concerning braking, pit speeds, and optimal race line speeds. These adjustments will be more noticeable at higher levels of scrutiny.
Gridding
- Fixed an issue where custom grids for Hosted Team Sessions were sometimes ignored.
Hybrid Deployment System
- The automated hybrid deployment system has been re-written with some slight improvements on deployment strategy.
- - The following vehicles are affected:
- - - Audi R18
- - - McLaren MP4-30
- - - Porsche 919
Fixed an issue with the manual deployment option for hybrid deployment systems where the offset was acting in the opposite direction.
Rendering
- The majority of the tiny pin-holes in the middle of the paved racing surfaces, where sky could show through from behind as bright speckles, has been fixed.
- Altered the non-VR driving camera's near clip from 10cm to 2cm, to reduce the amount of clipping away of objects very near the camera. This now matches the settings that are used in VR.
Visual Effects
- Tire smoke and dust cloud effects have been substantially upgraded!
- - Smoke and dust now provide a greater sense of volume and density.
- - Lighting and shading of smoke and dust clouds has been improved.
- - The sizes and behaviors of dust and smoke clouds have been updated.
- - Dust puffs kicked-up by spinning tires have been updated.
- Spark effects have been updated.
- The particle system's memory management has been optimized for improved performance.
Audio
- Audio levels for scrape sounds for all material types have been improved.
- Mild impact sounds for all material types have been improved.
XAudio2
- Replay Master Compressor, a new XAudio 2 option has been added to the XAudio2 sound options.
- - This is a multi-channel compressor/limiter that will work in surround, stereo and headsets.
- - - The effect can ONLY be used in replays to increase the volume of quieter sounds and mimics the dynamics used in TV Broadcasts.
- - - The compressor effect will give a perceived increase in overall volume but we have been careful not to allow the peak volume to exceed the levels obtained with the effect turned off.
- - The three options available for the Replay Master Compressor option are:
- - - None: Normal replay dynamics with zero effect.
- - - Mild: A noticeable compression of the dynamic range. The effect will boost the quieter sounds for a more consistent amplitude.
- - - Heavy: Simulates a higher level of audio compression similar to TV and radio broadcasts. The quieter sounds will be a lot louder.
- Replay Distortion: The replay cameras now have a microphone distortion setting for XAudio2 in the replay camera tool (CTRL+ F12). This digital sound processing was inspired by real-life TV broadcasts where track-side cameras exceed their sound pressure levels and start to distort.
- - This effect mimics a track-side microphone, usually with a lower SPL rating of around 100dB, picking up a loud car, such as a NASCAR at 140+SPL, whooshing past as though it were a mic mounted on the wall.
- - This setting allows you to configure a camera's microphone to sound less clean and more crunchy. The setting choices are: None, Light or Heavy.
- - - The sounds need to be pretty loud to start getting into the distortion. For instance - very close to a track-side camera!
- - - Additionally, you can use the camera's mic gain setting to push the sounds up into even more distortion.
- - - - A Word of Caution: Pushing a camera's mic gain setting too far may distort the softer sounds and possibly drive your audio device too hard.
- - We have carefully made the distortion effect dynamic, and this will allow relatively clean audio until a vehicle reaches a threshold where it starts to saturate into a crunchy yet smooth distortion. It sounds most realistic when a loud car passes a camera very closely.
Controls
- Logic has been added to only trigger a toggle variable if the underlying value was changed.
- - This stops toggle variables from triggering if a user selects the same value from a dropdown or spin control without making an actual change.
- The virtual mirror can now be resized with a new variable, "VirtualMirrorSize", in the [Drive Screen] section of the "app.ini" file.
- - You can set this variable to the following values:
- - - 0 = large
- - - 1 = medium (default)
- - - 2 = small
- - - 3 = extra small
- Support has been added for mapping a second throttle and brake input to match the second clutch input. This can be useful when using hand controls to gang two paddles together so both operate the brake or throttle. Or to combine a hand brake with an analog paddle on the wheel rim.
- - The hand brake, throttle2, brake2, and clutch2 control setup has been moved from the driving options tab to the control options tab.
- Fixed an issue where the "toggle selected control" hotkey was not working in black boxes.
Force Feedback
- A new force limiter has been implemented that reduces force feedback (FFB) generated when a strong vehicle crash or other extreme force event occurs. This system is designed to protect you from your wheel when it generates potentially dangerous levels of force.
- - A new limiter indicator on the 'F' meter illuminates when the limiter is engaged.
- - By default, this system is enabled. It may be disabled by setting the new "FFBUseForceLimiter=0" within the [Force Feedback] section of the "app.ini" file.
- - A new telemetry output, "SteeringWheelLimiter" has been added that indicates the force limit percentage being applied.
Cameras
- Live camera edits should no longer cause camera shake.
- Unused controls are now hidden during the camera joystick calibration.
- Scroll bars have been added to the camera tool config tab so dialog options fit better on the screen.
- Viewing distance is now prevented from going negative when setting up rendering.
- Fixed a bug that caused camera tool joystick calibration to fail in a Replay.
- Fixed several issues with blimp cameras.
Spectators
- An option for Spectators to be able to access the in-Sim "Start/Stop Spotting" user interface has been added.
- - This allows Spectators to view the live/extrapolated car positions in case they are spotting for a team that does not make them a team member. This might happen if the team does not want the potential spotter to see their car setup.
- - Spectator access to this interface is disabled by default, but can be enabled by hand-editing the "app.ini" file, and changing the newly-added "ShowSpotterUIForSpectators" setting in the "[spectator]" section from 0 to 1.
Telemetry
- A new flag, "irsdk_oilTempWarning", has been added to the "EngineWarnings" variable that is set to 1 when the oil temperatures get above 125 C. Just like the "irsdk_waterTempWarning" flag, this is an approximate value; some cars can handle higher oil temperatures.
- A new switch, "irsdkLimitFileSize=0", has been added to the "[Misc]" section of the "app.ini" file.
- - Setting this value to 1 automatically splits the .ibt telemetry files into 90 megabyte chunks that McLaren ATLAS can load.
- If live telemetry fails to load, disk telemetry will not be blocked from running.
- Fixed an error in telemetry logging of "CarIdxEstTime" that could cause the value to jump or report from a different car type.
CARS:
ARCA Menards Chevrolet Impala
- For the New Damage Model, the following adjustments have been made:
- - Adjusted the suspension system to prevent excessive hyper-extensions.
- - Wheel strengths have been upgraded; rear wheels should be tougher than front wheels to dissuade rear-endings.
- - Wheel tethers have been improved.
- iRacing setups have been updated.

- - Various changes to better align with real-world IMSA PC specification. Ride height rules, camber limits, fuel burn rate, fuel tank size and fill rate, minimum tire pressures and pitstop procedures have all been adjusted.
- - Various suspension parameters have been adjusted.
- - Rear toe adjustment range has been reduced to positive values only with finer adjustment increments (0.1 mm).
- - Rear wing range has been adjusted.
- For the New Damage Model, the nose and rear are now more resistant to visual scrape effects.
- iRacing setups have been updated.
Yup, huge update change log notes incoming - it's time for another new iRacing build update! Content wise, this latest build is certainly rich in new things for players to try out.

- Fixed the following incorrect behaviors and potential crash issues:
- - Fixed an issue where opponent car wheels would partially break but remain attached in the wrong position.
- - Fixed a Simulator crash issue that could occur when an opponent car with a detached wheel was reset to the pits.
- - Fixed a Simulator crash issue that could occur when a player car with lightly damaged wheels was reset to the pits.
Qualification Conduct Scrutiny System
- Some additional adjustments have been made for the Qualification Conduct Scrutiny System particularly concerning braking, pit speeds, and optimal race line speeds. These adjustments will be more noticeable at higher levels of scrutiny.
Gridding
- Fixed an issue where custom grids for Hosted Team Sessions were sometimes ignored.
Hybrid Deployment System
- The automated hybrid deployment system has been re-written with some slight improvements on deployment strategy.
- - The following vehicles are affected:
- - - Audi R18
- - - McLaren MP4-30
- - - Porsche 919
Fixed an issue with the manual deployment option for hybrid deployment systems where the offset was acting in the opposite direction.
Rendering
- The majority of the tiny pin-holes in the middle of the paved racing surfaces, where sky could show through from behind as bright speckles, has been fixed.
- Altered the non-VR driving camera's near clip from 10cm to 2cm, to reduce the amount of clipping away of objects very near the camera. This now matches the settings that are used in VR.
Visual Effects
- Tire smoke and dust cloud effects have been substantially upgraded!
- - Smoke and dust now provide a greater sense of volume and density.
- - Lighting and shading of smoke and dust clouds has been improved.
- - The sizes and behaviors of dust and smoke clouds have been updated.
- - Dust puffs kicked-up by spinning tires have been updated.
- Spark effects have been updated.
- The particle system's memory management has been optimized for improved performance.
Audio
- Audio levels for scrape sounds for all material types have been improved.
- Mild impact sounds for all material types have been improved.
XAudio2
- Replay Master Compressor, a new XAudio 2 option has been added to the XAudio2 sound options.
- - This is a multi-channel compressor/limiter that will work in surround, stereo and headsets.
- - - The effect can ONLY be used in replays to increase the volume of quieter sounds and mimics the dynamics used in TV Broadcasts.
- - - The compressor effect will give a perceived increase in overall volume but we have been careful not to allow the peak volume to exceed the levels obtained with the effect turned off.
- - The three options available for the Replay Master Compressor option are:
- - - None: Normal replay dynamics with zero effect.
- - - Mild: A noticeable compression of the dynamic range. The effect will boost the quieter sounds for a more consistent amplitude.
- - - Heavy: Simulates a higher level of audio compression similar to TV and radio broadcasts. The quieter sounds will be a lot louder.
- Replay Distortion: The replay cameras now have a microphone distortion setting for XAudio2 in the replay camera tool (CTRL+ F12). This digital sound processing was inspired by real-life TV broadcasts where track-side cameras exceed their sound pressure levels and start to distort.
- - This effect mimics a track-side microphone, usually with a lower SPL rating of around 100dB, picking up a loud car, such as a NASCAR at 140+SPL, whooshing past as though it were a mic mounted on the wall.
- - This setting allows you to configure a camera's microphone to sound less clean and more crunchy. The setting choices are: None, Light or Heavy.
- - - The sounds need to be pretty loud to start getting into the distortion. For instance - very close to a track-side camera!
- - - Additionally, you can use the camera's mic gain setting to push the sounds up into even more distortion.
- - - - A Word of Caution: Pushing a camera's mic gain setting too far may distort the softer sounds and possibly drive your audio device too hard.
- - We have carefully made the distortion effect dynamic, and this will allow relatively clean audio until a vehicle reaches a threshold where it starts to saturate into a crunchy yet smooth distortion. It sounds most realistic when a loud car passes a camera very closely.
Controls
- Logic has been added to only trigger a toggle variable if the underlying value was changed.
- - This stops toggle variables from triggering if a user selects the same value from a dropdown or spin control without making an actual change.
- The virtual mirror can now be resized with a new variable, "VirtualMirrorSize", in the [Drive Screen] section of the "app.ini" file.
- - You can set this variable to the following values:
- - - 0 = large
- - - 1 = medium (default)
- - - 2 = small
- - - 3 = extra small
- Support has been added for mapping a second throttle and brake input to match the second clutch input. This can be useful when using hand controls to gang two paddles together so both operate the brake or throttle. Or to combine a hand brake with an analog paddle on the wheel rim.
- - The hand brake, throttle2, brake2, and clutch2 control setup has been moved from the driving options tab to the control options tab.
- Fixed an issue where the "toggle selected control" hotkey was not working in black boxes.
Force Feedback
- A new force limiter has been implemented that reduces force feedback (FFB) generated when a strong vehicle crash or other extreme force event occurs. This system is designed to protect you from your wheel when it generates potentially dangerous levels of force.
- - A new limiter indicator on the 'F' meter illuminates when the limiter is engaged.
- - By default, this system is enabled. It may be disabled by setting the new "FFBUseForceLimiter=0" within the [Force Feedback] section of the "app.ini" file.
- - A new telemetry output, "SteeringWheelLimiter" has been added that indicates the force limit percentage being applied.
Cameras
- Live camera edits should no longer cause camera shake.
- Unused controls are now hidden during the camera joystick calibration.
- Scroll bars have been added to the camera tool config tab so dialog options fit better on the screen.
- Viewing distance is now prevented from going negative when setting up rendering.
- Fixed a bug that caused camera tool joystick calibration to fail in a Replay.
- Fixed several issues with blimp cameras.
Spectators
- An option for Spectators to be able to access the in-Sim "Start/Stop Spotting" user interface has been added.
- - This allows Spectators to view the live/extrapolated car positions in case they are spotting for a team that does not make them a team member. This might happen if the team does not want the potential spotter to see their car setup.
- - Spectator access to this interface is disabled by default, but can be enabled by hand-editing the "app.ini" file, and changing the newly-added "ShowSpotterUIForSpectators" setting in the "[spectator]" section from 0 to 1.
Telemetry
- A new flag, "irsdk_oilTempWarning", has been added to the "EngineWarnings" variable that is set to 1 when the oil temperatures get above 125 C. Just like the "irsdk_waterTempWarning" flag, this is an approximate value; some cars can handle higher oil temperatures.
- A new switch, "irsdkLimitFileSize=0", has been added to the "[Misc]" section of the "app.ini" file.
- - Setting this value to 1 automatically splits the .ibt telemetry files into 90 megabyte chunks that McLaren ATLAS can load.
- If live telemetry fails to load, disk telemetry will not be blocked from running.
- Fixed an error in telemetry logging of "CarIdxEstTime" that could cause the value to jump or report from a different car type.
