I have a program that runs at a nice clean 70 fps using DirectX 8 under windows 98. I recently switched to windows XP and my framerate has taken a serious dump. (8 fps) I have the same hardware I did under windows 98. My video card is an Nvidia GeForce2 MX-400. I''ve reinstalled my drivers, recompiled my code under XP, checked the creation of my D3DDevice (still HAL), and DXDIAG says hardware acceleration is enabled. Any ideas?? This is getting frustrating. --Ravenshadow

Had the same problem. Download and install the Detonator 23.11 drivers.
