This really brings up the whole processor speed and memory issue, as does the fact that we want to use multiple high-poly models with high-resolution texture maps. You're going to have trouble with these things on an average computer. If Curious keeps the ProPack distinction, it should not be in terms of "professional" versus "amateur", but simply about features that only work well on high-end machines. I would hate to see new versions of Poser not be usable by people with average machines, and also hate having innovation hobbled too much by having to accomodate lower-memory and processor speed computers. So maybe some of the things on this list should go in a pro version - one that they can really pull out the stops on. That might be Poser 5 - if they continue to sell Poser 4, or maybe a tweaked, but not too demanding upgrade of P4.
