Well, I have an Athlon with a NVidia graphics chip. So far, Poser 5 has not crashed on me once. The only bug I've encountered has been the focus bug. I would have liked to have seen a different interface, but I can live with the one we got. While it is true that Poser doesn't compare well with Maya in features, it sure does in price. OpenGL preview would be nice, but again, it wouldn't affect the final render. So why is it that important? Rendering speed? Yea, I'm a little disappointed with this. The Firefly renderer can take a long time to render, even with ray-tracing turned off. FWIW, I have an Athlon 1900+ with 1 GB RAM, 70 GB free space on HD. Even trueSpace with Radiosity turned on is faster. Hopefully improvements will be made here. Overall, I think Poser 5 was/is a good program. I am happy with it, and it isn't a doorstop for me.
