The current multi-core boom is an attempt to get around the problems of increasing processing power by just increasing clock speeds. With OS support, dual-core would let Windows itself run on one core, and an application such as Poser on the other, which is a help. But Poser's use of RAM, both the quantity and just how it does so, would still be a problem. The render engine, at least, would be capable of rendering one part of the scene on one core, another part on another, but Poser still isn't capable of splitting a render between two complete computers on a network; on the same computer you have to start being a bit smarter about memory handling. This is a weakness in Poser; at best you could render different frames of an animation on different computers. It's kept Poser at the low end of the CGI business, and now multiple cores are getting into the ordinary level of PC. Poser has other problems, but if it can't use multiple cores, it's going to look SLOW.
