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?

    LMDE only supports up to NVIDIA 535.

    You need to update to a newer release, I had to do the same 2 days ago.

    As of right now the only way to update to the newest nvidia drivers on LMDE or other Debian Bookworm releases is to use the official installer from the nvidia website.

    Put the installer in your root directory, blacklist nouveau, kill X/Wayland (stop lightdm to make sure it stays dead). As root from a TTY:#/nvidia*.run to run the installer, follow the instructions and READ CAREFULLY, if your system is not correctly configured at time of install, it will tell you, but will allow you to proceed anyway, don’t. Once all is done, verify your initramfs is good, and if you have a dual-GPU system (most gaming laptops for example) you should restore your xorg.conf from the backup the installer made.

    Happy sailing, good luck 🫡

    (Edit for clarity, I know this sounds like its an unrelated fix but it fixed this exact issue for me with Kingdom Hearts 3+Re-Mind

      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.
