Subject: Unexpectedly short RAM preview with 6K comp at 1/3 res

    So I'm trying to figure something out: I have a comp that is roughly
6000x3000, and when I RAM preview at 1/3 resolution I get about 160 frames
before the preview begins to loop. I have multithreaded hex core pc (12
logical, 6 physical cpus) and 64 GB RAM. running win 7 x64 pro. In my PC
monitor, the RAM only fills up to about 20 GB before it starts looping. It
doesn't seem to matter what the MP settings are, how many alternate cores
are reserved, how much RAM per core etc. I can't get more than 154 frames
at 1/3 res preview. Shouldn't the RAM fill up completely before I run out
of preview? The comp is using particular and has a couple tens of thousands
of particles, which isn't really that many. Rendering is fine and uses all
available mem. Turn MP off and behavior is as expected, using all RAM. But
slooow. Any ideas about why I can't get more frames in MP? Thanks,
TG
