IBM ThinkPad, Pentium III 850 MHz, 512 MG RAM, ATI card with only 16 Vid RAM, running Windows 2000 Pro. I use both Poser 4 ProPack and Poser 5 and don't seem to have too many problems. Don't know what you mean when you say, rendering hi-rez texture. I picked up the StefyZZ Yuma and though the software hangs a bit right after selecting those texture MATs if frees within a moment or two and I've never had any trouble rendering images. Using Raytracing settings in P5 is a bit slow but the process does finish eventually. Hope this helps, Rnce
