I'd be surprised if it ever reached half of what's alloted -- Windows doesn't let any program ever use more than 2GB total, no matter how hard it tries. I usually suggest more becuase that gives space for the overhead of windows and any other programs that might be running. In that case, look to the particulars of the textures involved AND the specific render settings in use. NOtably, the size of a jpg texture should be commensurate with the actual need for it as displayed, and this should be matched to a good degree by the maximum texture resolution and then sharpened by the shading rate -- both in render settings and on the various objects within the scene. The problem is associated with memory resources -- always has been. The problem is that we don't expect it to be because other programs use different methods for internal handling. It is outdated, but Poser 5 uses the same methodology used since Poser 3. That method is one of the simplest and least efficient ones when working with large files as the throughput on it is not incredibly high -- that's what ya get with legacy code that predates 2k and XP. The fact that they handle it better is a credit to the os designers. Now, that said, reduce by at least half and into a factor of 8 any textures over 2048 that will not be displayed at 2048 or greater image size (that is, a render where the are concerned is being rendered at the same effective size as the actual texture map). Beyond this point, it's sorta adding wasted overhead, as the shading rate parameters and shader settings can be used to effectively sharpen the resolution of the texturemap beyond that point -- a capability sorely lacking in poser 4. the only other issues I've encountered that can cause this are objects which are malformed within the limitations of the rendering engine to display them and driver interaction problems (which trend to manifest in other areas as well).
