I just recently got a new video card for my computer, a Firepro V7900, and am now having some weird artifacts show up in Simulation CFD. Any time I move the mouse (even when it is not over the model) I get odd vertical lines/planes that jump round on the model. I'm definitely not a computer person, so I'd appreciate any ideas. I did go into the ATI control panel thing and and change the anti aliasing to quality instead of performance. I also when to the Firepro V7900 web site and looked at the specific programs that they had drivers for, but they didn't list Simulation CFD. So, again, any othre ideas would be great. Thanks.
