I've tried 190.62 & 190.38. I can't remember if I tried it with 186.18 driver. Leaving 3D enabled also hosed my Windows 7 WEI score. It also lowers 3DMark Advantage scores. I'm not sure why it doesn't seem to like DX10 though. Do you have the CoJ DX10 benchmark? See if it slows down performance in that with 3D enabled but the effects hidden on startup.
