The game/engine requires the windows media foundation dll: mfplat.dll, MFPlay.dll, and mfreadwrite.dll, in order to run. If you get these three files from a windows 7 computer and place them in the same folder as the games executable, the game will start. DXVK will work if you have a graphics card with 4gb of ram or more. If your graphics card has less than 4gb of ram then you need to add PROTON_USE_WINED3D=1 to the steam launch options, or else when trying to spawn in the world the game will crash with a c++ error.
