@lchandelier Yes, try to clone/download https://github.com/joanbm/nvidia-470xx-linux-mainline and run ./install and it should work.

@mrBugmaker Regarding the liblgvnd warning, I never ran into it myself, but I believe it may be solved by installing libglvnd-dev (sudo apt install libglvnd-dev) and re-installing the NVIDIA driver.

However, I don't think that it's likely related to the problem that you're running into with Proton. Wine/Proton implement D3D11 by translating it to other APIs, like OpenGL or Vulkan. So even if your card supports D3D11 and the game runs over Windows 10, it doesn't mean it will immediately work on Linux.

I believe Proton uses DXVK to translate D3D11 to Vulkan 1.3, and this version likely supported by your graphics card (at least my GTX 660 caps out at Vulkan 1.2).

You may need to figure out how to get Proton to launch it using WineD3D to translate D3D11 to OpenGL instead, at least some sources claim this can be done by setting the environment variable PROTON_USE_WINED3D=1 <your_steam_or_proton_command> - unfortunately, I haven't tried this myself though.
