I'm working on a new bryce scene. It has over 6-thousand objects & over 1-million polygons. I went to copy this group and my pc seemed to hang up much longer than usual. I thought for sure that it had locked up. I did the "alt,ctrl,del" thing and brought up the task manager in Win XP. It showed that only bryce was up, but "not responding". OK - at this time I figure for sure that it is locked up and I'm going to loose my work if I click on the "End Task" button. For the heck of it I went to the processes tab and noticed that bryce was still processing that "Copy" command and using 99 percent of the cpu. It was working but way slow. I decided to wait and watch the processing for a while and I'm glad I did. It took over half an hour to complete the copy command. I knew this when I saw the cpu use drop to "0" percent for bryce. I then went back to the task tab and saw that the status of bryce went from "not responding" to "running". Great! I thought. Went back to bryce and did the "paste" command. Same thing happens exactly, only taking more than an hour this time. Went back to bryce and there was the new object. I didn't lock up or loose a thing. I saved the work and all is great, to my surprise. Has this happened to anyone else? And is it a common occurrence? Also is there a way of tweaking the pc to quicken this up? I'm running a 1800+ AMD processor with 512meg DDR ram and tons of hard drive space.
