I confirm:

• [x] that I haven't found an existing compatibility report for this game.
• [x] that I have checked whether there are updates for my system available.

Symptoms

Since the update to Unreal Engine 5, the game crashes with a shader compilation error when joining a server.

I also tried launching the game using the AMDVLK and AMDGPU-PRO drivers, but the game refused to start with a "DX12 is not supported on your system." error on both of those.

Reproduction

1, Make sure the Evrima beta branch is selected
2, Start game - May fail to load, but I don't believe that's a Proton-specific issue as it happens on my Windows 11 system too
3, Try joining any server

Fatal shader compilation error comes up, game closes
