I changed Proton to Proton 8.0-5 and it seems that it runs much smoother now! Thank you for the tip. But like i also mentioned, the graphics look grainy and bad (hope pasteboard is working here): https://pasteboard.co/J04DV6MLyjBy.png https://pasteboard.co/jw2C0cRoKIxU.png How can i get rid of this? Has this something to do with the shaders? I already disabled the steam shaders and re enabled it.

In the beginning, i used Proton Expermimental (i think) because of some problems starting the game. But i can check again and also try one of the stable versions.
