Gaming? Use Windows (and yes, although I’m a proud Proton user, some games just won’t work, like Valorant and PUBG).
I love proton on my steamdeck, and I’d like to try to go linux vs having to stay on win10 with no updates on my gaming computer. But outside of some games not working, a lot of hardware/accessories don’t have official support either. As far as I can tell, goxlr, streamdeck, and other hardware/software I use daily, have no official support, which for items I use that often makes it pretty much a non-starter on migrating.
