GeForce 3 low performance! HELP!!!!

[AkumaBao]

My GeForce 3 doesn't seem to be working as fast as it should. I first noticed this problem in Diablo II when my graphics would slow down at certain parts of the game. I've finally come to a conclusion that is definetly not a hardware problem. I first used it on my computer with an Iwill KA266 with a 1.33GHz Athlon TBird, 512MB DDR 2100, and an Enermax 431W ps with Windows XP. Changed the mobo to a Asus A7V266, and only got a +12degree increase on my CPU temp. I finally downloaded 3DMark 2001, and the results were horrible. I got a score of about 4300, so you can see my concern. I e-mailed blizzard 3 time, and recieved the same answer every time: Close all programs, turn off the perspective option, choose Direct Draw, etc. On the madonion site another system just like mine had a score about 500 point higher with less memory, and was PC133. My high polygon count (1 light) on 3DMark was 14, (8 lights) 3.1, EBM 60.9, fill rate (single tex) 432.6, (multi-tex) 1005.4 , and the rest were lower except for Vertex Shader Speed, Pixel Shader Speed, and Game 1 low detail. What is wrong!? Someone pleeeeeeeeeeeease help me!!

4 in 1 drivers for your motherboard

The latest VIA offers 4.34 I think.

I would load the latest via agp driver in turbo mode,
reinstall dx8a on your system.
Use the 21.83 drivers also!
Im getting 7400+ with a 1.33@1.5(fsb 150) and 240/535 for vtek gf3 I think in the least you should be in the low 6000+ range with no tweaking!

Also have you tweaked the bios yet?
