Yes, I think that I'm hit particularly badly as a heavy Poser user - the scene I'm working on at the moment has 5 Poser figures, three of them the latest Daz figures. I suspect that the problem may partly relate to bitmaps, and how Vue handles them. As a quick experiment I created a scene with two untextured Vickies, and one where the same figures were textured. In the textured case, making 20 camera moves (nothing else) lost 1% of system resources; in the untextured case the same moves had no discernable effect. In both cases, after moving the camera I deleted the figure group, and system resources DECREASED by 3%. You DELETE something and you use MORE resources! That's crazy.
