2022 Season 4 Patch 1 Release Notes [2022.09.14.02]

This Patch contains several updates and fixes for the 2022 Season 4 Release.


Fixed an issue where the UI Scale value was resetting to 100% regardless of what the real value was after reloading the iRacing UI.
The error message a user receives when attempting to launch iRacing using unsupported operating systems has been updated. iRacing requires Windows version 8.1 or newer.

Hosted Racing
An error message now appears when entering the incorrect password for a private Hosted Session.

Fixed an error that could occur when downloading Results.

Paint Shop
Fixed an error that could occur when selecting to use a custom paint pattern.


iRacing Forums
Forum moderation tools have been updated.

    • All iRacing Members Forum protests should be handled through the official iRacing Protest System.

The "Race Farm" field on the Info tab of the Session and Replay screens now include the appropriate "ipv4" or "ipv6" prefix for the race server farm name, based on how the Simulator connected to the race server.

Race Control
For the Tire Compound Change Rule, fixed an issue where the pace car indicated it needed to change its tire compounds, or it would be disqualified.

    • Fear not, it is safe from disqualification for not changing its tires.

Reverted a change that was disabling the auto-pit-speed-limiter during gridding and parade laps.

New Damage Model
Fixed an issue where damage was being distributed incorrectly to nearby mounts.
Fixed an issue for when a structure yielded to impact forces it was incorrectly calculating the deflection, causing too much damage. In particular, deflection of the other stronger object was taking far too much damage.

    • This was especially noticeable for the front wings of the Mercedes-AMG F1 W12 E Performance.
    • As a result of this change, all vehicles using the New Damage Model have been rebalanced for improved performance and realism.

For the LFE system, improved the engine RPM effect.

    • A low-pass filter has been added to reduce noise and a graduated RPM scale has been added to help keep the frequencies in the range most shakers can operate at, while still remaining harmonic with the sound of the engine.

Virtual Reality
Fixed an issue where Varjo headsets were not working correctly with OpenXR.
Fixed an issue where the view could flip upside-down when tracking is lost for Varjo VR users.

User Interface
Fixed an issue that prevented text elements from momentarily blinking, such as the Best Lap indicator.
