DgVoodoo is more than just a 3dFx->DX shim, it's also a DX(all up to 9?)->DX11 shim. It lets you force certain things like AA, mipmapping, scaling and resolution.
Given that it's doing it at the graphics API level it's a good alternative to forcing things in graphics driver settings. I used to only use it for getting 3DfX games working, didn't realise it also does directX.
