What will Poser's speed do when it gets subdevision in some future version?

It will be dealt with when that feature is developed. For the time being, I am all for the results that the high poly models give me.

Let tomorrow take care of itself.

I may be missing a point here, but I always thought the obsession with low poly count came from Poser's inability to use more than 2 Gigs of Ram. Since I went to 64 bits, I've NEVER had poly count be an issue in one of my projects.... and they get pretty complex with 7-10 characters and fully modelled enviroments.
