Um, that's what I have. Apparently doesn't work with d3d, as you said. OpenGL is no good (found it after opening launcher again today; don't know why it wasn't there before) since Vista apparently doesn't like it (something about W32)
I repeat D3D support is down. You have to use OGL
ALWAYS. Some builds don't use D3D even if you select them and in the future it will disappear completly.
OGL works completely fine under Vista IF YOU HAVE GOOD DRIVERS. Only Microsoft generic drivers are crap. Either ForceWare or Catalyst work fine. (But take in mind that some beta releases can be defective, the most recent example: ForceWare 169.xx Crysis series seem to be defective in OGL, stay with official 163.75)
