Mouse lag and Direct3D

[Chupa]

I'm having a problem. In every game I have that uses D3D (DEx, UT, HL) whenever I play in D3D mode, there is horrible lag on the mouse. The pointer doesn't move until at least a second after I've moved the mouse. I'm using NVidia's 6.47 drivers, and I tried with an earlier version too.
I think maybe it's due to installing DX 8, but I'm not sure.
Can anyone help?

My specs:
P3-750@860
256 MB RAM
CLAP GF DDR
SB Live
running Win2k

If you want smooth playing in games run win98se.

Can you even disable Vsync in win2k ?
