CHANGE LOG:
Simulation
- 32-bit versions of Windows, and running the 32-bit version of the simulation, has been unsupported by iRacing for some time now. As of this build, we have removed the 32-bit versions of the Simulation and other software from our distribution. You will no longer be able to install or run iRacing on 32-bit versions of Windows.
- DirectX 9 support within the Simulation has been deprecated for some time now. As of this build, we have removed the DirectX 9 versions of the Simulation from our distribution. We now only support DirectX 11.
- - The removal of the DirectX 9 version of the Sim will also now make the Sim incompatible with Wine software that allows the Sim to run on Mac OSX and Linux machines. However, you can continue to use your Mac computer to run the Sim using Apple’s Boot Camp utility and install a 64-bit version of Windows.
Control
- Speed up release of automatic parking assist brake when using a lot of throttle, to eliminate momentary brake drag when launching a car.
Dynamic Track
- Updated the mip mapping on marbles textures.
Rendering
- A new graphics option to adjust Sharpening Strength has been added to the .ini file. This is very helpful for Virtual Reality users, as it enhances edges and reduces blurriness.
- A new graphics option to enable Fast Approximate Anti-Aliasing (FXAA) has been added to the .ini file. This enhances anti-aliasing and makes pixels forming the edges of objects on the screen transition smoother between each other.
- In the Graphics Options screen, the text color of all post-processing effects that require a Sim restart to function has been changed. An asterisk explaining this has also been added.
- Enabled the super-high resolution screen-shot functionality using DirectX 11.
- The Ghost Car should now be less opaque the closer it is to you.
- Fixed a crash caused by headlight textures when Particle Detail was set to Low.
- Fixed an issue with heat haze and screen resolution.
- Fixed an issue with the Matte-Chrome settings for rims using PBR Shaders.
- Fixed an issue with night shadows being darker than intended and for shadows on self-lit geometry.
PopcornFX
- Particle debris performance has been improved.
- Fixed an issue where particles could be seen coming into the cockpit through the car body.
Animation
- Driver arms now interpolate better in slow-mo, so steering animations will no longer appear choppy in slow motion.
- Hand-over-hand animations have been added or updated on the following vehicles:
- - Aston Martin DBR9 GT1
- - Audi Quattro GTO
- - Audi R8 LMS GT3
- - Cadillac CTS-V Racecar
- - Chevrolet Corvette C6.R GT
- - Chevrolet Corvette C7 Daytona Prototype
- - Dallara DW12
- - Ford Falcon FG V8
- - Formula Renault 2.0
- - Holden Commodore VF V8
- - HPD ARX-01c
- - Mercedes-AMG GT3

- - NASCAR XFINITY Ford Mustang
- - NASCAR XFINITY Toyota Camry
- - Nissan GTP ZXT
- - Porsche 911 GT3 Cup Car (991)
- - Ruf RT 12R
Pace Car
- Safety cars may now be selected for hosted sessions!
- - A drop-down labeled "Safety Car" has been added to the "Optional Settings" section of the hosted session setup.
- - The default selection is always "Default" which means the current safety car for the track type is used (Mustang for Ovals, Ruf RT 12R for Road).
- - The available safety cars can change depending on the type of track selected.
Driver
- Filth threshold for triggering an automatic visor tear-off has been reduced.
Spotter
- Two new Indycar spotter packs have been included in this build:
- - Chris Wheeler - Chris has been on the spotter stand for over 10 years and currently is the eye in the sky for Indycar racer Sebastien Bourdais.
- - Darren Manning - Darren is an English racer who formerly raced Indycar for Chip Ganassi Racing.
- Fixed an issue with the toggling of the spotter calling out lap times.
Replay
- A camera cut is now forced when switching between any cameras during a slow motion replay.
Virtual Reality
- The sound system is now aware of VR headset movement, and will now move and rotate the sounds to match your movements.
- - There is a UI option to enable/disable headset audio rotation. By default this setting is on, for headphone support. But if you use external speakers (such as a surround sound system) with your VR headset you should turn this setting off.
- The VR mirror output (Rift/Vive) now zooms to fill the entire window, rather than black boxing the image.
Clubs

- The MGU-K deployment has been updated. "Adaptive" mode has been replaced by "Optimized" mode. Our first implementation of an Optimized deployment strategy is speed dependent. Below a set speed, a constant, low speed deployment value is used. Above that speed, a constant, high speed deployment value is used. The low speed deployment, transition speed, and high speed deployment are set by the user (either in the Garage or via the F8 Black Box). High speed deployment and transition speed may be mapped in the Controls section of the Options screen.
- - Please also note that we are working on our next iteration of Optimized deployment, which will take into account the car's position on the racetrack.
