This works really well! Combined with Boilr it's a great solution.
I *really* wish that the linux steam app would let me install Windows steam games, and try them in proton. Is that in the cards for the future?
So far, playability of linux has been pretty great. More than half the games I've tried have launched and worked without any configuration. Of the remaining games, less than half haven't worked after some basic configuration.
I'm really curious to try some windows games, but I'm not ready to jump through these hoops.
