The game is The Entropy Centre. Midnight Fight Express, which I have finished right before, doesn’t seem to be affected.

Since 2 days ago the game (not Steam) started returning the error:

"A D3D11-compatible GPU (Feature Level 11.0, Shader Model 5.0) is required to run the engine."

I am on LMDE6.

Proton Hotfix or Experimental or 9.0-4 are not working.

Proton 8.0-5 is the first one that works, but with some significant lagging, but I am positive I played the same version of the game using Experimental a few days ago with no lagging and on same Nvidia drivers (535.216.01).

An FPS counter titled VK (I guess from Vulkan) shows when running 8.0, while it didn’t in Experimental.

I have tried resetting the shader precaching in the settings, but nothing changes.

The game was also uninstalled and reinstalled, to no avail.

Any tips for debugging this?

    Damn, I am 2 weeks in Linux and this is giving me cold sweats.

    Thanks anyway! I know that if PewDiePie could, I know I can do it too! Always better than a nazi!

    Edit: Indeed this works! Apparently it is due to Experimental having been updated to Proton 10 to get fixes for some major new games.

    If anyone wants to to have an even more step-by-step guide about how to do this, I recommend https://www.if-not-true-then-false.com/ which has lots of guide and videos and useful comments.
