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.
That frame issue is because of the fact that Nvidia uses “explicit sync” and AMD/Intel use “implicit sync” - XWayland is built to only support implicit syncing for now (Nvidia is trying to get it changed), and since most games right now run under XWayland… Along with a ton of apps of course.
Until then, that issue won’t be resolved sadly. It’s what finally pushed me to get an AMD card since the issue has been open for over a year with a ton of back and forth.
