Symptoms

Game loads, but the framerate drops to average 4FPS with the native resolution of 5120x1440 (switch to 1920x1080 doesn't make much difference).

Reproduction

Start the game (v1.3.0 or v1.3.1).

I also tested the game with proton 7.0-6, experimental, and GE-Proton8-30.

The game used to work in v1.0.0 and v1.0.1.

Since then:

  • FSR2 updated to version 2.2.1 (in v1.1.2)
  • Unreal Engine updated to v5.3 (in v1.1.3)
  • FSR is temporarily disabled (in v1.3.1)

The funny part is that my GPU is listed as recommended (I know it probably works on Windows).
I can play Witcher 3 and Baldur's Gate 3, so I'm not sure what is the problem.

Still, thanks for the response @Blisto91.
