[Steam Deck] Lowland Meadows and Marin Woods Performance issues

Currently playing the game on the lowest possible settings without the entire game looking like a blurry mess. Default resolution. Performance graphics settings. FPS capped at 30.

Lowland Meadows and Marin Woods are making the game run unbearably bad. If I stand still, sits around 30fps. Move an inch and it tanks to about 15fps.

And on occasion the game just outright crashes in those regions.
