Linux Mint compatability

[76561198055008491]

Hello, I have a problem with running this game on linux Mint, specifically with Proton.
For some reason my FPS won't go past 5 frames per second when running the game.
My laptop is Legion Pro 5 16ARX8, it has an AMD Ryzen 9 7945HX with Radeon Graphics, with nVidia GeForce RTX 4070.
I don't think it's an issue of hardware.
I'm not really well versed with linux, all help is apreciated. :)
