It was for me at least, only moved to Linux after spending a long time with the steam deck

Honest question, what do you consider not compatible? I switched to Linux earlier this year and 100%'d Armored Core 6 (Verrrrry good game everyone should play it) and I’m currently playing through Cyberpunk 2077 + Baldur’s Gate 3 co-op with friends. If AAA games like these work pretty well I’d assume the vast majority of those 60k games work as well.
