iRacing | 2023 Season 4 Patch 1 und Hotfix 1 released

Changelog iRacing 2023 Season 4 Patch 1 Hotfix 1

SIMULATION

--------------------------------------------------------------

Security

Addressed an issue with local loading of assets across environments. (Fix deployed with 2023 Season 3 June release)

- - We would like to thank Ander Gómez for the responsible disclosure of the reported issue.

As a reminder, security issues can be reported at infosec@iracing.com.

Graphics

Options have been added so users can more directly control dynamic object shadows in mirrors.

- - Previously the "Higher Detail In Mirrors" option would control turning these shadows on for mirrors, and cube maps would always include these shadows.

- - We've changed this so there is an option to control if dynamic object shadows are used for the main view or for both the main view and mirrors. We've also changed cube maps so that they will never render dynamic object shadows.

- - This allows users to use higher detail mirrors without the additional cost of shadows. It also makes using cube maps less expensive.

Fixed an issue where the maximum allowable rendered shapes amount was too low for the recent graphics changes to the Deferred Rendering List with 2023 Season 4.

- - Overrunning the shape buffer was causing the user to crash out of the Simulator.

Race Servers

Fixed an issue where a driver could crash the Simulator when transitioning from an Open Practice race server to a Race race server if their video memory usage would exceed the video memory slider’s limits.

Tires

Off-track surface parameters have been rebalanced for tire interaction.

Audio

Removed the "disableWindowsCoreAudio" entry from the “app.ini” file, as WindowsCoreAudio is essential for XAudio2.9.
