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.
As someone on Linux, and who thinks performance is generally slightly better on my machine after switching, I totally agree. This post has been old for a while now. Get some more data and then post that new thing or stop posting it.
