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.
YMMV of course but I was playing Timberborn just the other day on Mint, on an Nvidia card, through Heroic. Proton seems to have been a gamechanger. I have just made my first steps into switching my daily driver myself. I may have been lucky but all the games I have wanted to play have worked so far. I also have a Steam Deck, which is what has encouraged me that it may be possible.
