Please don't get the wrong impresion I'm not getting the dual for poser - That 's nessasary for other things I want to do. But from what I've seen a 500mhz machine will not work. The memory he had in the machine was 512 with nothing but win 2000 and p% on board - like I said - he was just showing me how it would run on a machine similiar to mine. How he set it up as far a mem allocation I don't know. i was only on it for 20 minutes. Once I brought the hair in it froze up. No Props nothing other than hair. I tried it in wire frame and still wouldn't budge. Slow I can deal with, I am now with some of my appz. But not stand still. Thats why I ask what are the TRUE min sys requirements.
