I have a similar problem, sometimes the game runs smoothly, sometimes you can see micro stutters (graphics tearing). Sometimes after restarting the micro stutters disappear
Gentlemen,
Personally, I've also had similar issues with stuttering and general underwhelming performance. (RTX 3080 + 5800X)
As for the stuttering, for me it became mostly a problem of the past after switching to windowed borderless instead of fullscreen.
No idea if it will work for you guys, but it sure did for me. Also the nvidia shadowplay overlay was working normally again when it wasn't in fullscreen. My guess is that this is related to the anticheat trying to fight it as a false positive. I suspect the anticheat to be mostly responsible for the games stuttering and performance issues...
