Poser has the problem of backwards compatibility with the most primitive geometry engine one can imagine. That's what you're paying for-- for people to continue to develop for all those gigabytes of stuff you own. Poser has the unique problem of a large user base, heavily invested in massive geometries . . . sitting on an architecture which dates back to the 1980s. There's no question that newer architectures are more powerful-- but where do you find the oodles of content for them? You don't . . . Someday, someone is going to figure out how to do smart decimation of the high poly Poser characters, rendering their detail to normal and displacement maps, so that we can work with low poly, low memory impact models, and still render beautiful stuff. That's the way zBrush does it-- but how to back out all the zillions of man years of work in Poser characters? No easy way, not anytime soon
