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.
For whatever reason, Windows 11 is worse at Cyberpunk 2077 than Arch for me. Constant stuttering. It might be that Arch has much less going on than Windows, but it's enough for me to use Linux as my main gaming OS now.
