I am not sure any app can even use 2GB of RAM effectively. Also, keep in mind, if you are running WinXP, a large amount of RAM gets allocated to the OS on boot. As far as allocating your virtual memory to Poser, you cannot manually tell the virtual memory where to point to. You could manually increase the amount, but this is not advisable. Windows actually does a good job of memory allocation to virtual memory, it's one of Win's good features. Poser is slow people. It does a lot of disk I/O. One day maybe I will sit and test just how much occurs during a good render. My assumption is a lot. Increasing RAM in this situation is not going to help much. I really wish EF would consider selling special versions of the product so that we users with multiple computers can use the power of our networks to make render farms. That would help greatly.
