iRacing.com release substantial new build update, includes brand new LVMS Bullring Oval.
With a release of dirt just around the corner iRacing.com have today released a major new 2017 Season 2 build update for the game, adding a substantial number of fixes and improvements to the simulation including yet more hand over hand animations for some of the cars, frame rate improvements for the Imola track and dynamic audio tracking for Virtual Reality users amongst other things.
Other additional improvements of note include "extensive vehicle tyre changes" that apply to a number of cars in the game, predominantly affecting a number of the GT3 specification cars found within the simulation.
As mentioned just this weekend, the original plan was for this build update to include the first pass of dirt loose surface racing, however a decision has been taken by the developers to delay this release until the end of the month. The new proposed release date for dirt racing will be March 29th.
You can read the release notes in full below.
Release Notes for 2017 Season 2 [2017.03.06.01]
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.

- 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.
Updated the trigger for the rain light flashing when MGU-K deployment suddenly drops. The light will now flash whenever deployment drops by at least 80 kW while at full throttle (and not on the rev limiter.).
