I posted about memory problems in the Poser Technical, and got no replies. On my own, I think I have discovered two things. One is that if you are using Internet Explorer at the same time as Poser, IE will gobble up your memory because it doesn't clean itself out. I also increased the virtual memory setting to 384 MB (I have 128 MB RAM). I haven't been having memory problems of late (don't know what contribution the virtual memory made). However, my renders take forever, and I hear that hard drive working hard on the renders. I would also guess based on my limited knowledge that upgrading your RAM should be a big help, and it wouldn't force you to buy a new system. Upgrading the chip should speed up processing time with renders, but it isn't going to give you any extra memory.
