Nier: Automata terrible performance (524220)

I was very excited to get this game, but once I got it, I was disappointed by the performance. I think a lot of the animations and things in the game are time based (which makes sense for a console game but not for PC), so if the frame rate drops to even 58 fps, its already laggy as hell. I've seen on steam community posts that the FAR mod is pretty much required to have a good experience on PC. We've got to figure out a way to get more performance out of this game. I know its not my PC, as I'm running a Ryzen 7 2700X, and dual R9 Fury cards.

Can we figure out a way to maybe install the FAR mod?

Start by reviewing the linked system-information gist and reproducing Nier: Automata under Proton at the reported frame rates. The issue names no source files or tests; done would require a reproducible diagnosis of the performance problem and a clear determination of whether the FAR mod request belongs in Proton.
