Recent testing revealed that Arch Linux, Pop!_OS, and even Nobara Linux, which is maintained by a single developer, all outstripped Windows for the performance crown on Windows-native games. The testing was run at the high-end of quality settings, and Valve's Proton was used to run Windows games on Linux.
What have you been doing. Cause for me it’s just install steam enable proton and install pretty much any game on my library. Or install lutris login to my accounts and play epic games / gog games. It literally just works
I know this is a very common experience, but for me it fails. The list is too long but belive me I’ve tried it. It’s probably some weird driver issue or some thing I use for x y or z that conflicts. Who knows.
