No, 64 bit means a lot more than that. Running a 64 bit program (and you need a 64 bit OS) gives you access to a lot more memory and greater speeds. I run 24GB on my home machine, which means vastly decreased render times.

Ah. 2 Different things. 64 bit memory bandwidth and 64 bit colourspace. Both available in poser pro 2010+

still hooked to real life and enjoying the siesta!
