What games do you have? Most of my games work great with steams proton. Only some multiplayer games with some anticheat are not supported. I think from my ~260 Games +90% are working Check out protondb.com

Only because Ubisoft does have problems. If their finances would be better they would’nt do it. That’s my opinion. I will never trust this company again.

I do have the same error but i installed bnet via steam. Changing the runner to another proton version (official proton and proton-ge) wont change anything. How to change to a wine-ge version in steam? Or is there another fix? I tried a few of the suggested things from the links but nothing worked :( My OS is Mint 22 Cinnamon I do have proton tricks but no winetricks.

No update available (stable) and rebooted multiple times. Sadly no change :(

I read this with the „i need a dollar“ sound

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.
