I'm using 9950x3d, When I was playing Counter Strike 2 and using process lasso to make it runs on ccd0, the game beginning lagging,like 1 times per minute, I need to switch to the desktop(Win+D)and back to cs2(Alt+Tab),The game return normal.
But Sometimes,when i switch back to game, it crash.
When i stop using process lasso, it become normal, even i play for 5 hours.
If the CCD rule is causing problems, you should remove it. If you've also set rules on the game launcher, you may need to remove them as well, or all rules. Then take some time to assess whether the crash was definitely the result of the CCD rule. Sometimes such crashes are intermittent and hard to pin down to a specific cause, but if it was indeed caused or exacerbated by the CCD rule, then leave those rule(s) removed.
Try unistall your drivers first, use the DDU and i reccomend you use it the NVCleanInstall for your drivers install.
