This game is unfixable if it doesn't just run on your pc. I tried different video drivers, different gpus, different proton versions. Most proton versions wouldn't even get past the first sound. The game froze after that. Proton 7.0-6 opened the game consistently, but once in-game the game just ran with 2s frametimes. Not miliseconds, seconds. It was completely unplayable. Trying vulkan resulted in an immediate RAM leak. The game filled up every bit of my 32 GB PC and fully crashed linux to the point where my pc shut off. Only the DX version "worked", but everytime I got ingame it was a slideshow.

I was very excited to play and looking at the protondb page it seemed to run, but I was completely unable to. I tried the initialization settings in every configuration, not just all 4. Used hephaistus to even get the game to open in a multi-monitor setup. My setup has an iGPU and a dGPU. I run all the video through the iGPU. The valve github thought it was a radv problem, but eventually decided it was just a game issue. After 2 hours of troubleshooting I gave up and asked for a refund. I refuse to pay for a game that just doesn't work on my pc in the hopes that someday it will get fixed.
