I am looking at performance and seeing interesting numbers also, but not the same ratio you are reporting. I have an animation that has been rendering for over 10 hours. CPU is pegged out at 98 or 99 without letup The peak memory usage says 615,980K Memory useage is flickering around 450,000K as I watch. VM Size flickers along around 490,000k sometimes it goes up and down from there, but maintins aprox the same ratio. note: I have 4Gig RAM on board and the pagefile set at 4290MB. my other processes are not moving and add up to less than 100,000K So......either these are acurrate figures and Poser is utilizing only around 1/2GigRAM and yet swapping out more than that to the hard drive (even though I have 2Gig sitting there waiting for it), or....these numbers are somehow 'ghosts.' For instance, Poser might be "finishing the task" of what it can do with the processor in one cycle in just that one-half GIG and then it is waiting for the next cycle, etc. In otherwords, the bottle neck is the CPU and there is over-abundant RAM. However, I agree with you and have been asking quite a while on other threads: then why is it swapping out to the HD -- why can't it stay completely in RAM? I hope some of my hardware mentors see this and chime in. I am very low on the knowlege food chain with this stuff. ::::: Opera :::::
