Please note that they really, really SUCK for glide. If I play a game in glide mode, it jerks quite a bit. The frame rate is usually livable, but there are these pauses every 2-3 seconds or so. The game just freezes for 1/2 a second. It makes the game really unplayable. I have noticed this in 3 games using glide, and as soon as I switch to D3D, it goes away.
My system is a p3-733 w 256 MB ram, so I doubt it is the system. The card in question is a V3-2000 O/C'd to 170 MHz.
EDIT:
That card is a PCI card, I am not sure if that makes a difference or not.
