I do 99% of my PC gaming with a Steam Deck. All the major games I am interested in "just work." If Elden Ring and most/all of my fav indie games work, I don't see why I will need a windows PC ever in the near future.

I was able to get several non-steam games from the early 2000's working as well with Proton.

Likely if more games are built against/for dxvk/proton things will get even easier.
