Simulation

Dynamic Track Model
- Improved the calculations for track debris accumulated and thrown by opponent vehicles.
- Improved the throwing and spreading algorithm, especially for gravel, for a more realistic and uniform distribution.
- Fixed a critical issue where some developer code for the Debris Refresh remained available for adjustments by drivers.
- Fixed an issue where the new debris type, gravel and mud, were not being cleared correctly between Sessions if the option for cleaning the track between Sessions was enabled for an event.

Weather
- Values for rain on track surfaces have been smoothed, so puddles are more visible.

AI Racing
- Fixed an issue where some AI Drivers in Formula cars believed themselves to be indestructible and unaffected by damage sustained - they would simply not pit for repairs and just keep racing even when heavily damaged. It may benefit some Members to take note of this corrected behavior.
- Fixed an issue where AI Drivers did not understand Fast Repairs and would refuse to pit to fix damage whenever Fast Repairs were available. They now understand these are good, and should use them when needed.

Graphics
- Fixed an issue where Anti-Aliasing settings were incorrect after upgrading from an older "renderer.ini" file.

The Test Drive Service which is available whenever iRacing is down for maintenance has been re-built from the ground-up, is integrated seamlessly with the iRacing application, and is now known as Demo Drive! Our graphics and physics developers have tag-teamed an outstanding upgrade to the debris system which now includes mud and gravel, and all debris types are now easier to see and impact racing much more realistically. We are pioneering some upgrades to the iRacing netcode system with this Season Release, including improving the experience for a lagging driver as well as everyone else in the race with them. The lighting for the entire iRacing world has undergone an improvement which increases contrast and reduces some excessive brightness. Your spotter will now inform you if any damage you receive is going to have a negative impact on an aspect of your vehicle performance. AI drivers have also now been trained in the art of headlight flashing when passing.

Our hydromancers have prepared the Formula Vee for rain racing, and ALL FIVE new cars come equipped with a unique set of rain tires. AI Racing systems have been programmed and implemented on six cars, including: Acura NSX GT3 EVO 22, BMW M2 CSR, Ferrari 499P, Supercars Chevrolet Camaro Gen 3, Supercars Ford Mustang Gen 3, and Williams FW31. AI Drivers have mastered Thruxton Circuit and two of New Hampshire’s Road Courses.
