Having been on Linux for over a year now, I don't. It's still plagued by instability, weird bugs, and big limitations whenever non-Steam games are involved.
You mean games that arent available in steam at all, vor those which you haven't bought there?
I found the easiest workaround for me was to simply add the games to my steam library and to launch it from there. Then I don't have to worry about what proton version I should use or whatnot.
If you want a Couch Gaming Station I recommend you to look at ChimeraOS. Linux first that boots directly to Stream Big Picture (since it's based on SteamOS) and it supports emulators and Epic Game Store.
On my old i5-8700T with qUHD630 it pretty much was a install, reboot, login to Steam and start playing.
My Wireless Xbox Controller USB dongle was plug'n'play.
What brand of graphics card do you have? If it's Nvidia Pop!_OS will likely work best. If you have an AMD card I've heard good things about EndeavorOS.
Also, feel free to shop around for a desktop environment (DE) you like, which controls the look and how things are organized. While distros have a default, it's pretty easy to swap them. I personally use KDE Plasma (the same DE the Steam Deck uses) with Pop!_OS
And it really is the good fight in this case. I've been running Linux on my gaming PC for around four years with very little trouble. Games from Epic and GOG run very well(for me at least) through Heroic Games Launcher. I've been using Windows for work on/off the last couple of years, but especially since they "upgraded" to Windows 11, it's such a relief to come home to Linux.
Sorry, I'll wait some more. I tried two times getting back to Linux as I see the potential. It didn't work. I'm gonna stick to windows until some problems will be fixed, or Microsoft further enshittifies itself.
