That does seem strange.. though you might want to list specs on vid card.. mb cpu.. chip sets.. drivers and last time updated so forth.. someone might have a clue =)
Iwill KK266Plus-R Latest bios
CPU-AMD XP 1600
VIA KT133 Not the newest beta, but new (heard lot of bad stuff)
GeForce 3 Ti 200 PNY not oc'ed, 23.11 dets
Directx - 8.1
512mb ram
u can make sure by hitting Via's site and getting the latest non beta 4in1's I'm sure somwthing like Sandra would tell you though.. but I never thought about it =)
4in 1 can cause some bad times with 3d mark so that could be it.. b/c everything else looks fine to me.. drivers r updated.. humm do u have the latest service pack installed for windows 2k? that could cause issues as well when it comes to gaming..
