I run p5 on 96 megs ram and 233 mhz pII, If you want to know the tricks of the trade for rendering on slow system, I'll let you know. (10 g hard drive!!!) no problem, THAT'S WHAT I HAVE!!! You don't need a big fancy system to get the most out of poser 5, from procedural shading nodes to the latet volumetric lighting with hdr faking, let me know. I'll help you with what I know, I'll refer you with what I don't. It's all about learning here!
