Operating Systems

I've been using Mint without any issues for a while now. I only play Steam games, though.

I have my gaming computer hooked to my TV and running Chimera OS. Makes it easy to use with just a controller.

I've been using Fedora for the past few years and have been pretty happy with it. It updates at just the right cadence for me where I get new stuff pretty quickly but I'm not on a rolling release.

I'm on Arch right now, migrated to it after almost 2 years on Fedora. I'll probably still go back and forth between the two.

I use Arch with KDE. I don't recommend Manjaro because it has historically had some serious problems, so for people who want Arch without as much hassle, I'm recommending EndeavourOS. It's what Manjaro should be like.

Don't see it mentioned here - Nobara. Fedora tweaked by Glorious Eggroll to be as compatible as possible with games ootb. Worth looking at.
I used to use Arch but Nobara works too well for me to go back.
A big thing for me too is the custom version of OBS that the welcome GUI installs is excellent and allows for application specific/exclusionary audio sinks so I can screen record games without having audio from discord/music.

Fedora but I'm about to move to NixOS Unstable or VanillaOS if it gets better NVIDIA integration.

I use Arch, but I have two graphics cards in my system and I run a stripped windows VM for any game that I want ray tracing or 4k in.

My arch setup has an older Nvidia Quadro card and can run everything on like medium settings, but my virtual machines have a 3080ti. I didn't want the wear and tear on my 3080ti just to watch YouTube or play indie games that don't need the horsepower, but I still want to try stuff like portalRTX or stable diffusion and the like that needs an enthusiast graphics card.

This to me is the best of both worlds. I can run the VM in the background so I can use my desktop(connected to the TV) as a media center and have cyberpunk playing totally hidden and streaming to my steam deck for ray tracing maxxed settings.

Hell I even play Half life:Alex VR in a virtual machine and stream it over wifi to my Oculus quest.

Been gaming on Gentoo for over a year, even if I haven't found much time for gaming in the last few months.

Don't do it if you've gotten too lazy for Arch though. Try Pop!_OS or Linux Mint or something. Enjoy an easy distro for a bit, till you get the itch for Arch back.

On my gaming desktop, I am using Fedora currently with the Awesome WM. That might change though with all the RH stuff going on. On my gaming laptop I switch between Arch and Void with Qtile on both.
