iRacing 2023 Season 3 Patch 2 Released

iRacing deployed a patch last week that I had not posted about yet. The update includes tweaks to the dirt update, graphics tweaks and a fix for 12th-gen Intel CPUs.

Build notes:

SIMULATION:

————————————————————–

Optimization

Improved the Enki worker thread pool allocation algorithm.

– – This allocation adjustment should greatly improve performance for Enki threads on Intel 12th Gen CPUs.

Options

Helpful text has been added to the voice chat notification dropdown menu.

Dirt Racing

For the Dirt Refresh Project, reduced the variance in the amount of water in the track on dirt road courses.

For the Dirt Refresh Project, dirt displacement from tires on dirt road tracks has been reduced slightly.

AI Racing

AI Drivers now classify cars in lower classes more as obstacles rather than other drivers, which should allow for much more decisive passing. They are also hard-coded to think slower drivers are pathetic, so up your game!

AI Drivers have improved their passing techniques for cars at very different speeds. They should move laterally to pass at a more optimal distance from the target.

Further improved AI Drivers’ lateral positioning alongside other cars while racing on Road tracks.

Spotter

The spotter message for setting the overall fastest lap will now only play for Open Practice or Race Sessions. In lone sessions, the personal best message may play instead.

Graphics

Fixed an issue in Windows 11 where VSYNC could not be disabled when running the Sim in a window. This also fixes an issue in Windows 11 where the graphics auto-config always detected high-end GPUs as low-end GPUs, due to the test getting locked to the refresh rate and messing it up. This change also allows VSYNC to be toggled for windowed modes for the first time, and also now VSYNC setting changes take effect immediately without restarting the sim.

– – NOTE #1: there are cases due to Windows and device drivers where VSYNC settings don’t work still, where VSYNC won’t turn on. For instance, usually it doesn’t work if running using NVIDIA Surround, etc.. Also device driver settings may be overriding the Sim’s application settings.

– – NOTE #2: When launching in full-screen mode with VSYNC off, if you Alt+Enter or Alt+Tab out of full-screen into a windowed mode, VSYNC will usually automatically enable until you Alt+Enter back into full-screen. It seems to be a DXGI limitation.

Force Feedback

Fixed an issue that could cause the wheel force slider in the Options tab to fail to auto-detect your wheel if you had not yet entered a car.

Some additional wheel models have been added to the force feedback auto-detect routine.

CARS:

————————————————————–

GT3 Cars

For the New Damage Model, a tuning update has been completed which lowered the stiffness of rub blocks.

Audi R8 LMS GT3

Fixed an issue where some mirrors would appear at the incorrect location when the New Damage Model was in use.

For the New Damage Model, strengthened the rear wing and rear body panels.

For the New Damage Model, fixed an issue where heavy damage to only body panels could erroneously cause a Meatball flag.

Dirt Late Model

(ALL) – For the New Damage Model, a tuning update has been completed which increased friction on the right side-panels and tire sidewalls, stiffened the right rear corner, and lowered the break limit on the front wheels to make wall riding more dangerous.
