Title pretty much says it all. Anyone else running into this issue?

Setup:

• rtx 3050 , nvidia 525 drivers(game doesn't load with 535 last I checked)
• Running the DX11 version of the game
• i7 10th gen
• proton experimental
• high graphics settings
• 2 person direct connection. Second player has practically the same setup but i5.
• Ubuntu 22.04

For the most part the game runs at a beautiful 45 - 50 fps but 8/10 times after I save, it drops to 10-15 fps and stays there. I've been reloading it every time and it gpes back to 45-50 like nothing happened.
