iRacing: 2025 Season 1 Patch 2 Release Notes

This Patch Release for iRacing 2025 Season 1 includes various improvements, updates, and fixes across multiple areas of the simulator.

The primary changes impact the anti-cheat system, race control, AI racing, graphics, vehicles, and tracks.

Detailed Changes

Simulation

Anti-Cheat

• Additional steps have been taken to remove the previous generation of iRacing’s Anti-Cheat system (Kamu/EAC).
