While testing the new GT3 cars at Barcelona, I kept having the game abruptly go to the loading screen then immediately close itself to the desktop after maybe 3 or 4 minutes of in game play. No crash log is generated at all from what I can see since it isn't an explicit crash. I tested this with all the GT3 cars, and there is no difference. For reference, I have a custom FFB file loaded and I have ReShade running on the game. I verified the integrity of the files once, but the problem still persists. I also made sure to run without reshade as well. Edit: Seems like I was missing a few files after all, got it running now. Be sure your integrity check actually works.
I have same exact problem. Any car any track, crash after 3:30. Managed to fix it somehow... deleting some files from ams2 folder then atleast 3 times verify integrity did work.
