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.

Important: Nobara is way less Secure than Fedora.
If you want to game, stick to regular Fedora. A project that is actually secure is ublue with dedicated NVIDIA images that should just work and never break, and they even have Bazzite, an Image specifically for the Steamdeck but also for Desktop.
These images are only ½ day behind upstream, apply minimal additions and patches (like drivers, codecs, packages, udev rules for controllers) and Nick from the video above found out that the Nobara patches with their weird less supported Kernel arent really worth the hassle.
