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.

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.

I've been running Pop for a bit over a year now and am (mostly) satisfied with it. The only issues I had were due to kernel updates, it would cause flickering on my screen and (like someone else mentioned) had to revert to an older kernel until the situation was resolved.

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

Most of my gaming these days is done on my Steam Deck running stock SteamOS. I also play a few games on my main Linux Mint system.
