Yeah I had it set there and I couldn't open the WoW Client to play it... I would get a DX9 C Error something to do with my 3d Accelleration..... ? Anyway around that.. I am running windows 7. I can post a DxDiag if needed. I had to run a WoW Repair to get the client to boot... and set it back to Dx11 to get the client to run.
