I got a RTX 3080 myself and no matter what distro I used the new gamepad UI lagged so much that it was unusable.. maybe this has been fixed, I haven't tried it in a while.
Also are you using x or wayland?
But you can Dual Boot and only use Windows for gaming. I did that initially
Sadly I wont switch until this is resolved. But I use this rig only for gaming and navigate through gamepadui so I dont have to see Windows lol.
I use UNIX (Linux / macOS) on all other hosts.
Started on Manjaro but I was annoyed when they let their SSL certificates expire several times so I moved to EndeavourOS. Now I am using NixOS, and I probably stay with it for a while.
Nix is a good tool, but don't think I'd personally want to give up the Linux FHS for it. Manjaro's management does indeed have a somewhat concerning track record.
I'm guessing they're distro hopping. People often jump from Manjaro to Endeavor to get a more clean Arch experience. This is what I did too, on my laptop a couple of years ago, and I've stayed on EndeavourOS since.
Do you ever run into upstream bugs, or Idk, package version incompatibilities, on Endeavour? The idea that the 2-week package grouping and delay might help avoid those is one of the main things that drew me to Manjaro.
