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.
I dual boot arch and windows 11 at home. In World of Warcraft arch is behind, and I haven’t figured out what the problem is. Something just feels off with it. With any luck they’ll continue to improve compatibility. (likely Nvidia driver diff)
