Actually, I just did a pretty huge rendered image in Poser 5, and only 512MB of RAM.... It was very slow, especially the pre-render phases such as textures and shadowmaps. But it was working. Unfortunately, there's nothing while loading textures to show whether anything is happening. 2400x1600, but I was using Posette-based characters, three of them. And that's still less than one Vicky 3. Anyway, try setting things running and leaving the machine for an hour or two. If you get past texture-loading, you might get something from an overnight run.
