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.
I 100% agree, its best to just stick to upstream Fedora imo. Glad you made this comment. The security issues of Nobara always put me off, especially since basically everything it does can just be applied to regular Fedora. I think Nobara would much better serve as a script or toolkit, similar to Brace, or something along those lines instead of an entire separate OS with the security issues it brings.
