I just built a new system with an sapphire x800 xl and when ever i try to play halo it wont run it. It tells me there was a problem initializing Direct3D, or hardware acceleration may be turned off. It said to run DX Diag and DX Diag said Direct 3D was running properly, and i checked hardware acceleration and it is on. In the ATI Catalyst Control Center it says hardware acceleration settings not available. So if anyone has any suggestions on what i should do i would greatly appreciate them.
