Funny you checked protondb for the previous ones, but not BG3 itself. It's out in early access, people have been playing the early acts for a while now.

It's rated gold. https://www.protondb.com/app/1086940/

Larian's previous game (Divinity Original Sin 2) didn't have a native port, the one before that did. I think it's unlikely that BG 3 will get a native port but it seems to work well enough through Proton.

Which previous games were you looking at by the way, BG1 and BG2? BG3 has little to do with those except for the setting, it's a really different game (some dislike it for that).

@root if you’re into rpgs, Baldur’s Gate 2 is one of the best ones ever made.

The current early access runs without any issues through Proton.

I'm hopeful

i played at BG3 one years ago with wine & proton, and it works perfectly,
