2026 Season 2 Patch 4 Release Notes [2026.05.04.02]

—---------------------------------------------------------

Patch Release:

This release is a Patch, focusing on additional updates, improvements, and fixes for the 2026 Season 2 Release.

Simulator

—---------------------------------------------------------

General

• After installing this Patch, customers with NVidia GPUs should expect a Windows Security popup related to allowing public and private network access for iRacing.

  • This is appearing as a result of preparations for the release of the Apple Vision Pro device support, coming soon!

  • If you do not have nor intend to use an Apple Vision Pro device, you can disregard this request.

Race Control

• Fixed an issue where the pace car could speed out of the pits at an unrealistic velocity, only to pick up the wrong lead car.

  • This was most often triggered in sessions with AI Drivers. Fred, Flawless Wheelman, has improved his ability to identify the lead car.

• Fixed a “ghost tow" issue where in extremely rare circumstances could cause a driver who had been black flagged for a connection quality issue to potentially gain a lap on the field with the right timing.

Race Servers

• Fixed an issue where the host of a session using AI Drivers could potentially connect to their session inside an AI vehicle. Initial studies indicate there should be no long term adverse effects for temporarily embodying an AI driver, but we’d like to see these humans again in 6 months for a follow-up!

AI Racing

• AI Drivers have improved their racing line at Watkins Glen International - Boot.

User Interface

• The raceline toggle keybind (Ctrl+Alt+L) may now be used in Replay mode.

• Fixed an issue where the Weather Radar displayed incorrect track map dimensions upon loading.

• Fixed a crash-to-desktop issue that could occur when advancing to a next Session while on the Drive screen.

• Fixed an issue where tire checkboxes were getting double-clicked when they had previously been mouse clicked and the user was using the default space bar binding to toggle them.

Tracks

—---------------------------------------------------------

Watkins Glen International

• Adjusted track limits. In the bus stop entry, 4 tires off = 1x. Half-a-car past the middle curb's left edge is a slowdown penalty.

• The inner loop entry track rules have been updated.
