I am using EndeavorOS, my first Arch flavoured distro, it's excellent. Honestly it has all "just worked". Drivers were auto installed, I pointed Steam to my existing library on an NTFS drive originally used by windows, and it just plays my existing library fine.
Cyberpunk2077, Red Dead 2, Starfield all objectively AAA modern games, working fine. I even get a bit better performance in some areas, comparable in others.
I can swap back to windows and it still runs the same library. I really didn't expect it to work like that.
The only thing I have had to troubleshoot is getting a Quest3 VR headset to work, and an Alpha stage game which others are getting to work, I just haven't bothered to chase it down.
