I just recently formated my computer and installed a copy of Win7 64bit ultimate.
However certain games such as Oblivion I have installed doesn't seems to recognize my graphic card.
I could still get in the game but the frame rate is around 14-15 which is skipping like crazy, I tried to reinstall the video driver and Direct X driver which doesn't help at all.
Following is my comp's Specs
CPU: Intel I7 920
Mother Board: Asus P6T Deluxe V2
Memory: Corsair 3 X 2G Tri Channel
Graphic Card: Asus Nvidia GTX295
Hard Drive: 2X !TB Western Digital Black FALS Raid 0
