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.
This. While the experience for Gaming on linux is still not perfect, or as easy as install and play, Heroic is a good start. It still requires configuration and many hidden configs are not always obvious for the user, but I managed to run every game I threw at it flawlessly so far. All AAA games, and games from 2000 (Hitman, C&C games, Jazz Jackrabbit etc…), GoW, Cyberpunk, Hogwarts, etc. On a RTx 2070.
Between Steam, Lutris, and Heroic I can run every game I’ve tried on Linux.
