[Proton] FPS Drop at exactly 35 mins every game

[elijahrane]

I get an FPS drop at exactly 35 minutes every game. I figured that even though this is supposed to be unsupported, this might be useful information regarding whatever happens at 35 minutes if it's causing issues for other people. My FPS reduces from very high to a very choppy 20. It is fixed by restart. Graphics settings:
