Yes, you'd think so. I guess we'd have to get the answer of exactly what it's doing from CL, but it sure seems to be at least 'processing' the loaded data, if not loading it all over again. The step/phase where Anton is seeing the improvement is in the "Adding Objects.." state. I suspect this has something (everything) to do with the render engine being separate from the display engine. BTW, just for the record... I ran V3 through the process... reduced the filesize by about 300k. I timed several renderings and got mixed results on my system (P4, 2ghz, 1gig memory), but there did seem to be a 5-10 second overall decrease in total render times. I suspect that 'your mileage may vary', depending on the particular model(s) in question and your system particulars.
