You have enough ram, If Poser takes a long time loading, maybe your runtime folder is too big? I try to back up stuff I don't use to streamline it some. Try defragmenting your drive that helps. Test render small and without aliasing until you are ready for the final, and render while you sleep or watch TV!! I also have 512ram and run NT4 with a dual PII450 not the fastest thing but livable.
