OK, next Q. I am finding that with a complex scene (270 objects) the response time of Vue is awful. The camera controls are almost useless - I try and drag that trackball with the mouse and the program responds three seconds later, which makes accurate positioning impossible. I have improved matters a bit by putting most of the static stuff on a separate layer that I can turn invisible, and that speeds things up to tolerable. But sometimes I need to see all the other objects to get the scene right. (And yes, I do have OpenGL turned off). Would things improve if I installed more physical memory? I have 512 Mb at present.(And a 1.8 GHz Athlon processor).
