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).

    I'm sorry i can't post a clear video. When i save a video with shadowplay the problem disappear.
    I think is the opposite of motion blur.

    Example:
    I look at the racing wheel. When i move the head the edges of the wheel became "fuzzy" (i think is the right english meaning of the opposite of blurry) too definite, out of focus.
    So it is also visible especially on the edges of the cars in front of me...

    I upload two pics:
    In one video camera is steady
    In other video when i move the head, or when others cars are moving. It last half a second and it not ever appears. The effect in the image is enlarged because it's a still image from a video.

    That's commonly referred as ghosting. There might be one of two reasons for it:
    1. Temporal antialiasing produces a ghost afterimage, you can see that best with follow cam in a replay. Change antialiasing to KTAA, should get rid of most ghosting from AA.
    2. Displays need time to change from one colour value to another, so you might see an afterimage of the old frame still on screen. There are overdrive methods to force a quicker change, but if those are too sharp there is the side-effect of a brighter ghost image not unlike the cars in your screenshot.

    If changing antialiasing method doesn't improve the picture, it is your display, and other than buying another display or using an overdrive mode, there is nothing anyone can do - it's a hardware limitation.
