I did some Linux gaming during COVID and recently swapped my HTPC to Linux (Bazzite/Deck) for a console style setup in the living room.

The game I was playing heavily at the time (Wildmender) absolutely runs better in Proton on Linux than it did on Windows. Less crashes, less stutters, faster load time. I assume it is due to preRendered shaders? Honestly not really sure but it is nice.

Going to do some Enshrouded on it next which is a game absolutely not at all optimized for Linux, so far it seems to be working fine but I’ve not gotten to that late game CPU intensity of loading areas heavily modified.
