Excessive Jitter Blur When Rotating In Quake III W/Visiontek 64M Geforce2 GTS

[JohnnyGHz]

Just finished putting together a gaming system for a friend.

-PIII 650 FCPGA @ 910Mhz (FSB=140Mhz,PCIB=135MHz)
-ASUS 4040BX CUBX motherboard
-Promise ATA 100 Disk Controller
-Maxtor 30.7G Ultra ATA100 7200RPM Disk Drive
-2 PC133 Mushkin 128MB Dimms (Cas 2, Rev 2)
-Visiontek Geforce-2 GTS 64MB DDR video card (Rev A)(Detonator 3 Version 6.31)

I get this jitter blur in Quake III whenever I turn or rotate during game play.

The Geforce 256 32M DDR Video card in my 800 Mhz machine seems much smoother.

I've tried everything. Maybe I have to turn off sidebanding, but I don't know where to get the registry program that inserts the code

anyone have a suggestion?

Thanks Guys
