I was commenting on this just last week. Gaming on Linux has exploded since the Steam Deck was released (just as all Linux users were hoping it would).
All the effort which went into Proton to get games working on Steam Deck has done wonders for the desktop.
It used to be that you could play AAA games up to about 2 years prior (same story like macOS today), but now you can play almost anything on desktop Linux. I even run HiDPI / 5K monitor and it all works now, at least on Arch.
The only notable exception (truly, a surprise), at the moment, is Starfield not working on day 1. This was surprising, but the reasons net down to GPU drivers - and progress is already being made.
