Not correct, Obsidian are making a non mainline Fallout game, kinda like New Vegas. Bethesda are working on Fallout 5 themselves, as the article states.

Not OP but first I check protondb to see if anyone else has the same problem, then I try swapping proton versions if noone else has the same problem.

Worst case scenario it’s my nvidia GPU drivers doing stupid shit, then I try updating my drivers or giving up and playing rimworld instead.

Most of the time just checking protondb works though.
