What are these? Does the HD4890 have all of them? Cuz in DXDiag video settings I don't see the OpenGl disable or enable or w/e funcionality while I do see the other 3. But does it still have openGL even though I don't see it? BTW for AOE2 to work for my pc I have to disable DirectDraw which also disables Direct3D. It's a 2D game. Will it work if I just disable Direct3D I think DirectDraw speeds up 2D acceleration or something. Correct me if I'm wrong. Thanks.
