I recently upgraded my workstation from a 1.8Ghz with 768megs of Ram and an integrated video card (Dell Nvidia), to a 3.0 Mhz comp with 1Gig of ram and an ATI 3100 GL 128 card. SW seems to be running worse than it did before. It is choppy when I rotate a part, (even a small part not an assembly). I read that I should disable the hyperthreading, which i have done. Is there anything else I should do to speed this up? All of the options settings are low. I should be able to work faster with this machine.
