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.
Linux and Nvidia don’t mix well, at least not until Nvidia’s official open source kernel module has been upstreamed to the Linux kernel which will take years.
Breakages, workarounds for breakages, etc. are common occurrences, especially when you want to use a modern desktop using Wayland.
Other than being completely unable to run Wayland, secure boot, and being forced to use a propietary driver what kind of things are specifically wrong with Nvidia on Linux? Maybe it’s because I switched to Linux fairly recently but I haven’t noticed many Nvidia specific issues yet.
