Well, I run Poser 5 on an AMD 1800XP(1.5 real MHZ?!) with 512Meg SDRam. But with Win ME. AT CL they wrote that WIN 98 AND ME couldnt handle more than the 128 MB. But give a "Hint" how to get around that Problem. www.curiouslabs.com/link/category/15/?df=1 Well, i dont "feel" the diffrence! ;) But that may depend on the details/Objekts/Figures in you Scene.(For example the DAZ Mil. Dragon. They wrote:WARNING: The Millennium Dragon is a highly detailed model made of over 60,000 polys and will tax some machines ....." So for me it seems that you need the fastest CPU you can get AND as much RAM as your Board can handle AND Win XP? ;)) And after a Week this machine will be tooo slow too! ;)
