As already said,wow! Im working with an Athlon XP 1800+ and 1024 MB ram. Even my computer wouldnt feel convenient. In the handbook I got with Vue 4 600000 polygons are announced the be the limit! My scenes are about 2 million polygons,and even programms as cinema 4DXL (6.3)are getting slow ,I can tell you! So reduce the amount ,use less in the background and more in the foreground when necessary. rollmops :-)
