I have noticed a marked slow down in Poser 5 and was wondering if you know if the amount (quantity) of models, poses, lighting etc impact the performance ? I have the latest service pack loaded but the processor can be working at 100% for up to an hour and locking the machine while it loads a new texture or model. Spec: P4 2.3 with 1GB ram and Gforce 4 graphics card and plenty of free hard disc space. Some lighting can bring the computer to its knees. Is it me, or do other users suffer from ultra long computing times ? Thank you for reading. Tony
