Would need to know your PC setup but I would take a guess that you are using a AMD card. I have issues using dgVoodoo with this game as DX11 is broken with AMD cards so I'm forced to use the DX12 renderer. It seems that something has changed as now I use to be able to play this game and now it just refuses to run with the DX12 option, which I have the same issues with other games now too. Either AMD made some changes again or something else, but either way I can no longer run this game with this.
So if I want to play I have to remove dgVoodoo and run the game with Disable fullscreen o
