Symptoms

Performance is atrocious while Windows users have shown to have around twice the performance using FSR3 with the same graphic card and a comparable CPU. Using FSR3 on Linux doesn't give no where near the same result.

I get around 40-50 FPS with FSR3 running at 1440p resolution. The Windows equivalent runs the same settings with 80-90 FPS.

I also get drastic ghostly frames which makes the game blurry.

I am not sure that Proton is responsible. This might be an issue with Mesa or vkd3d-proton. I'm looking for advice to pin point the issue so that I can use my system to its full capacity with this game.

Reproduction

Just play the game and see the bad performance.
