I have an Inno3d Tornado GeForce 2 MX PCI video card and have been having problems. In graphically intensive games I play with vast landscapes (namely Black & White and Sacrifice) the landscape has a tendency to mutate on its own. Close up to it is fine, but as I zoom out, it just keeps mutating and transforming into different shapes. As soon as I stop moving, the landscape stops. In Sacrifice I was able to set it at the "Insane" setting of graphics intensity and this seemed to stop the problem, but made the game lag a bit.
Thought it's probably irrelevent, my system is a PIII 700mhz with 256 megs of ram. If anyone has any suggestion on how to fix this, please don't hesitate to respond. It's really an annoying problem!
