Steam, Lutris for league of legends and GOG’s games and even Heroic Launcher for GOG’s games with cloud sync for save data of games or Epic. Everyone works very well on Arch.

I think Arch Linux could be for you. You can install it with archinstall script. It’s relatively straightforward.

Ye , I think the list could be more large if I buy other games. Oh, I forgot Cyberpunk and Battlefield 4 and EA App through Lutris. The only issue I found is the compile of shader cache of Apex Legends and Hogwarts Legacy. It’s a lot of time to compile.

I use GTX 1660 Ti and I had some problems, but nothing of impossible to solve. I use Arch with zen kernel and nvidia-dkms with XFCE as DE. List of games that I play: Apex Legends, Hogwarts Legacy, Grime, Ironsight, Albion Online, Nostale with Steam. League of Legends with Lutris. Vampyr, Bioshock Remastered 1 and 2 with Heroic Game Launcher.
