Hey, I have a really bad video card. its on board with my motherboard, a VIA/S3G UniChrome Pro IGP. Since using nQuake/ezquake whenever I do things like go underwater it locks up my videocard...and computer. As in, as soon as my character goes underwater the computer freezes. To give some idea of how it performs with other games, Videocard does better with direct 3d than open GL from what i've seen, has a ok-ish ammount of ram but is not capable of direct x 9b or watever the one that has the fancy wrappers (required for doom 3). It locks up and gives some error when I try load regular GLQuake, yet i can play quake 3/GTA san andreas and few other dated games.

Is there some GL or water console setting I can turn off to stop this happening? Thanks in advance for any help.
