Around 12,000. fitting sim and posing sim each take around 5-7 minutes each. I often am working in photoshop with 300 to 500 meg files and if I go strait from there to run a sim in the poser cloth room it runs rather slow. If I run clothroom sims on a fresh boot it runs really pretty fast. I work on a 4 year old machine with 2 gig ram and a athlon64 dual core processor.
