2023 Season 3 Patch 1 Changelog

---

SIMULATION:

Security

• In the Season 3 release on June 6th, 2023, changes were rolled out to improve the security of the iRacing update processing. We would like to thank Stephen Shkardoon (ss23) for the responsible disclosure of the reported issues.
• – – As a reminder, security issues can be reported at infosec@iracing.com.

Optimization

• For the newly added Enki loading optimizations for 2023 Season 3, we have reports of stuttering from users with 12th and 13th-generation Intel CPUs as well as AMD 7900X3D and 7950X3D. This Patch limits the maximum number of allowable Enki worker threads for iRacing to use to 10.
• – – With our internal testing, this seemed to alleviate the stuttering issues, and no other negative impacts were found for any other users.
• – – This update also allows users to manually adjust the maximum number of allowable Enki worker threads for iRacing to use. To do this, create a new entry in the “core.ini” file, “[Task] max_num_default_worker_threads=10”. Adjusting this value will control the maximum number of Enki worker threads iRacing is allowed to use for the default thread pool.
• – – – – We would like to hear from you with regard to this issue! If you have a system that utilizes Enki worker threads, please let us know how these changes work for your system, and how changing your maximum allowable Enki worker threads changes your performance.

AI Racing

• AI Drivers have improved their braking techniques.
• Fixed an issue where the BMW M Hybrid V8 and Cadillac V-Series.R GTP AI Drivers would fail to load into Sessions.

Graphics

• The way in which we check for GPU memory has been updated. This impacts how the Graphics Auto-Config sets the memory slider for users.
• – – Now, the iRacing Auto-Config tool should set your memory sliders to about 80% of available memory.
• Fixed an issue where some car tires did not have ambient occlusion working correctly.

Replays

•  Fixed an issue that could cause the Simulator to crash while watching Replays with AI Drivers. AI Drivers are less shy now.

Controllers

• The shift light behavior for Thrustmaster T128 and T248 devices has been updated to better match that of other wheels.
• The amount of time we suppress data collection for the Force Feedback (FFB) Auto Button has been reduced when an incident is detected. This may help the Auto Button work more consistently at some tracks.
• The Force Feedback (FFB) Auto Button will now continue to collect data when driving under Caution or on the pace lap.
