I cant tell when this started but somewhat around within the past 2 months. When i first start the game and join a server it does run butter smooth, no lags or shutters whatsoever. But after around 10-20minutes mostly one major lag happen and after that i receive frame drops every few seconds, doesnt matter where i am it happens everywhere. Big lags happen when i zoom in with right mouse button. But overall while normally walking i receive fps drops, i do have 80fps for example in the apartement secion of cherno but the fps drops go down to 30 and up again, resulting in a small lag, usually in many actions such as raising/aiming with a gun.

So this continues until i close the game and restart steam, once i did that the game runs good again but after 10-20min it starts again.

Also i cant close the game properly, once i click on the X to close the game, the screen kinda freezes and it takes 1-2minutes until the game finally closes itself and my pc gets on its limit.
