No offense taken, and I'm sure open-minded to all and any possibilities, but I've had dozens of machine configurations and Poser 4 has been lousy with all of them. Of course, I've considered Curious' tech suggestions, but the program performs as badly with a fresh install on a brand-new machine, with the latest drivers, as it does on something less pristine. I don't like to be suspicious, but in my experience, software vendors ALWAYS blame everyone except themselves, and hardware vendors always blame the software people... I'm sure no Poser expert, but I'm reasonably competent with PCs. The fact that this is the only program that shows such poor performance definitely makes me point the finger back at Curious. Thanks for your suggestion though..
