I have a flatmate who is making the switch from windows 10 to linux and I Fedora is a distro that I trust to provide a good stable experience. I however use Nobara which comes with all the gaming related tweaks already done. I dont want to recomend Nobara because its package management is intuitive.
The changes i think I need to make is, remove fedora flatpak store. Enable non free software repo. Install proprietary nvidia driver. Install steam, wine, lutris, heroic store.
Is there anything that is required for a smooth Fedora gaming experience?
nothing i don’t think, you did everything to make it a functional gaming system. install the drivers if applicable, then your game launchers.
dunno why you removed flatpak, it should be fully functional if your friend is to use it like he does his windows machine.
