Spent the last few days trying out Manjaro linux on my home gaming PC. Same conclusion as always - lacking in finish for gaming.
Specific issues - Wayland + Nvidia is still a "you have to do all this fiddling" mess to get it to work.
Tried it with X11 instead, but then half the stuff in Lutris doesn't work, and the response for others with similar issues is "all the devs use Wayland, so you're on your own".
Doesn't seem to matter how much time goes by, the Linux community stays the same.
