What changed
Fixes
- iRacing says this hotfix contains critical fixes for issues introduced with the 2025 Season 3 release.
- The high CPU usage warning has been narrowed: it now appears only when there is an active network alert and the CPU alert level would be high (red in the system meter).
- Moza 360 Hz and Wheel LFE effects have been temporarily disabled.
- iRacing says it is investigating a critical issue with Moza that can cause the sim to crash after about two hours of operation, and plans to restore the feature in a future patch once a stable fix is ready.
