I have a weird problem where during the first 10 minutes (circa) after launching the game, it runs relatively smooth, but after a given amount of time the game starts stuttering a lot and is unplayable. I have tried messing around with all the graphic settings and nothing happened, and i don't think it has to do with the mouse either, since i tried the hardware cursor mouse fix. Does anyone have an idea what may be causing this to happen?

Laptop?

No I'm on PC

If it's not a temps issue, this subforum searching shows a lot of 'stutter' topics to check out, so reason may vary.

turns out it was a problem with my GPU or something, appreciate the input
