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. 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).
  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.

Lower Performance after a while

    I recently got a new pc ( i7 9700k, rtx2080 super, ssd, 16gb ram) and discovered a major issue.
    when i restart my pc initally the performance is great, +-140 fps in benchmark but after a short while (+-15minutes) i notice lower performance. when i benchmark again the loading is a lot slower and the benchmark stalls at +-65 fps. no matter what i do i can't get back to 140 fps in the benchmark until i restart.
    I have tried different driver, disabling background apps, trying all kinds of settings in cm, csp and sol. AC through steam instead of cm behaves the same so it's not cm.

    has anyone encountered this problem or does anyone have suggestions?

  3. Nice specs.

    Compare system temps from the peak to low benchmark results.

    First thought is thermal throttling over time.
    That would explain performancs taking a moment to decrease.

    What case, cooler, fans, and flow configuration?

    this is the setup i got, but with a different cpu, gpu and a EKL ALPENFĂ–HN SELLA EVO cpu cooler.

    Here are some screens, first is when performance is fine, second is after 15 minutes.
    the only thing i notice is it's hitting 70+ degrees, could it be throttling that low?

  5. I assume not.
    Only thing that stands out is CPU usage climbed to nearly max on some cores over time which kinda makes sense given how much more stuff os being piled up during the length of a race.

    I think you would have to run a proper 3rd-party benchmark to see what the true system temps are because for all we know Task Manager did not see the spike causing thermal throttling if it did occur.

    I never expect races to remain at a constant fps over time, especially on race starts, but that is a huge drop.

    You could check out LinusTech or JayzTwoCents on Youtube for some quick tips on testing such things.
