Symptoms

The game struggles to run at "playable" framerates.
30-50 FPS at save select

15-30 FPS on plaza/level select

<15 FPS in-game

additionally I've tried multiple proton versions: 7.0, experimental, GE, with similar results. The game runs fine on my steam deck which makes this issue even more odd...
