Hey, this might mean running the engine is not supported on your computer. Please consult the troubleshooting. If this is persistent, you might need to use another DirectX version. Currently the game supports DX11 and DX12, but I can compile for DX10 and DX9 too, even Vulkan and some older graphics methods. These will likely be uploaded as special versions here when I feel a "last patch" for V0.3 is ready.
