I was working at a Bryce file that was not that complicated but it involved 50 torouses. Everytime I made a change it took my computer 50 seconds to think and perform the task. Is it the processor or the video card that is not refreshing the screen fast enough. When changing from create to edit menu took 50 seconds I knew I was not using my time properly! I have a Pentium 200, 128 megs of Ram and 14 gigs of hard drive. Any suggestions? Thanks, Andres.
