There are two releases of Dark Souls 2. DX11 2015 and DX9 2014. I have the DX9 version, which is the one that supports G3D in vorpX.
The game will not start for me with Vorpx. It starts fine without VorpX. I am trying to figure out if this is a bug, or if anyone else is able to play this version using VorpX.
