Nooo, 333MHZ bus speed, Athalon XP2600(just under 2.1GHZ). Yes, I tried set things low in the hair room, I just wanted to see what the hair looked like in an AVI. I have been having luck with the cloth room(sweet), but not with the hair. The dynamics calculate decent, but rendering to AVI doesn't go so well. How come CL responds to you?
