Xp and detonator xp 21.81 performance

[jonnyurso]

I've got very low performance with detonator xp running on windows xp pro.
My system:
p3 1ghz
ABIT BE6 II
256 ram pc133
IBM DLTA 307030
Asus v6800 deluxe (geforce ddr)
windows xp
detonator xp 21.81

scores:
3dmark 2001: 2200 marks
3dmark 2000: 4300 marks
quake2 demo1: 187 fps
quake2 crusher: 96 fps

This is not normal...I've configured a p3 700 with the same hardware in windows me and in quake2 for example it scored 186 fps demo1, 95 fps crusher, 6500 marks 3dmark2000.
With an athlon 900 in a kt266 board on windows me i´ve got in quake2 218 fps in demo1 and 118 fps in crusher.
Is it the os?
What's wrong?
I'm confused because i've changed processor and operating system at the same time and i don´t know if there is something wrong with my hardware.

I tried those drivers also and saw a significant decrease in performance. Seems like those drivers really suck.

Did you tryed these drivers?
Can you give me marks or fps with the current drivers and with the detonator xp drivers? What system do you have?
Thanx
