That game uses ddraw6 by default, and would have never worked with DXVK, unless you use some kind of mod?

I'm using CNC TS Client 7.01, and I switch the render to the CNC-DDRAW.

C&C Red Alert 2 is also a ddraw game. I'm assuming you're using cnc-ddraw's d3d9 renderer for that as well? Note that cnc-ddraw has an opengl backend and you should be using that directly for better performance anyway.

Try setting: renderer=opengl in ddraw.ini.

Seems fine here, even with cnc-ddraw d3d9 + dxvk, not sure what the problem is on your end.
