Hello , i came back to the game after a long time , and as i started playing i was surprised with horrible stutters and low fps , all drivers are up to date , gpu is a 3090 rtx , cpu 5900x amd , 64 gb ram , win 10 last version , and game is installed on an ssd with 600 gb free space . the fps is around 70 with 99% fps fluctuating at 5 and so . Monitor is 2k allienware ultimate gsync 240 hz. And as i said all drivers are up to date , the can you run it website gives the 100 of top 100 games can be played , and any other game runs at max ultra graphics with no issues 200 fps and so . Please , i really wanna get back in the game , but at this moment and state it is just infuriating with the stutters..
Try the experimental branch. I don't know if it will fix any of the issues you're experiencing but for me the game is much smoother and my fps is now locked at 60 instead of fluctuating like it does on live (I don't have a good monitor so 60fps it is for me).
