1. Do you need support for Assetto Corsa Competizione? Please use the proper forum below and ALWAYS zip and attach the WHOLE "Logs" folder in your c:\users\*youruser*\AppData\Local\AC2\Saved. The "AppData" folder is hidden by default, check "Hidden items" in your Windows view properties. If you report a crash, ALWAYS zip and attach the WHOLE "Crashes" folder in the same directory. Do not post "I have the same issue" in an existing thread with a game crash, always open your own thread. Do not PM developers and staff members for personal troubleshooting and support.
  2. As part of our continuous maintenance and improvements to Assetto Corsa Competizione we will be releasing small updates on a regular basis during the esports season which might not go through the usual announcement process detailing the changes until a later version update where these changes will be listed retrospectively.
  3. If ACC doesn't start with an error or the executable is missing, please add your entire Steam directory to the exceptions in your antivirus software, run a Steam integrity check or reinstall the game altogether. Make sure you add the User/Documents/Assetto Corsa Competizione folder to your antivirus/Defender exceptions and exclude it from any file sharing app (GDrive, OneDrive or Dropbox)! The Corsair iCue software is also known to conflict with Input Device initialization, if the game does not start up and you have such devices, please try disabling the iCue software and try again. [file:unknown] [line: 95] secure crt: invalid error is a sign of antivirus interference, while [Pak chunk signing mismatch on chunk] indicates a corrupted installation that requires game file verification.
  4. When reporting an issue with saved games, please always zip and attach your entire User/Documents/Assetto Corsa Competizione/Savegame folder, along with the logs and the crash folder (when reporting related to a crash).

    VDXR works on poco 4, gives much more constant performance (crashes on session exit)

    Using Virtual desktop (oculus not the Steam version) OpenXR API, the Router is wifi 6 compatible running at 5Ghz.

    Running all Ultra settings, desktop resolution 1024x768 but the quest3 @ default resolution.
    There are no lags, it runs pretty sweet.
    My HP G2 is just collecting dust.

    Very impressed with the Quest3, it can also run normal Steam games pretty well Via VD Airlink.

    I just can't believe the VD air link is far better than the Oculus air link.

    Finally I can enjoy ACC, Gawd it`s good to be back.

    Yes you can and even with cable link.

    on your computer you need to install open composite and openxr toolkit. with open composite switch acc to use openxr in order of steamvr.

    Then start the cable link from your quest 3, switch to desktop view and start acc by choosing steamvr. as you switch steamvr to openxr with open composite you will run the game with openxr.

    To get better performance set fov in quest debug tool, then in openxr set a FR (foveated rendering). You can also tried one of the ss (with my rtx cas set to 100% give me the best sharpen images)
    Enjoy!

    How does Open composite decide what is in the configuration area?
