Update:
Ok. I ran the driver removal tool, rebooted, reinstalled the 4.5 drivers, and left everything at default. (no Rage3D tweaker)
My 3DMark01 score jumped to 10500 (up from ~8700). That seems a little low, but closer to norm. I found my copy of 3DMark03 and ran it. I got a 2400. That doesn't seem right at all. Also, it tells me I can't run 2 of the tests. :-( Is there any utility that can tell me what could be wrong here? Maybe a hardware problem like a non-functioning pipeline or bad video ram?
My Farcry FPS is still in the mid 20s. (800x600, medium)
My UT2K3 FPS is in the upper 20s. (1024x768, medium)
My Q3A FPS is ~140 now (1152x864, max detail)
All these just seem rather low for my system. I'll try to remove the drivers again, then manually clean the registry, then try the Omega drivers.
