Does extra RAM speed up Poser? Let's go back to the very beginning. I was using Poser 2, but I was also using a Mac Classic which had very little RAM. Fortunately, Poser configured it so that I was able to use part of hard Drive as virtual RAM. The benefit of this was that my classic didn't have to spit out it's operating system disk every minute or so. When they added virtual RAM, rendering took me only half as long.
