Hello @Rodhin, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to https://github.com/ValveSoftware/Proton/issues/438#issuecomment-483738338.
GPU: GTX 1050ti
Driver/LLVM version: nvidia 418.49.04
Kernel version: 4.4.172

Proton version: 4.2-2
Same issue, here. Bad fps, and it seems like no settings affect performance. (I reset graphics options to default, around medium, where I was able to play on all high on the OpenGL renderer.)
Log from running it: https://gist.github.com/garpu/bd9d23b1821bbb5f4a6b5f95a9947d02

Symptoms
Today the game received an experimental branch, they will switch from OpenGL to Vulkan. The OpenGL version runs like a dream, but the Vulkan version barely runs with 2-5 FPS. When the next big update is released for the game they will drop the OpenGL renderer completely.

Reproduction
Switch to the experimental branch and launch the game.
