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.
It’s funny because you say that and at the same time it’s the first question asked when someone has a hard time gaming on their Linux setup, “Nvidia GPU?”, even in this thread it’s come up.
