I can understand rebuild times, but what is this whole "generating graphics" stuff. I have a quadro 4000, and I am working on a part with 2-4 bodies, no current transparencies, but fairly "swoopy" This design was done a while ago and I don't remember these long delays in generating graphics. It was orginally done on a system with (2) FX 3800 cards. I have the image quality turned quite a ways down, but is there another setting I should be looking at? I have realview turned off.
