*I know that sounds strange, but "ecosystem polygons" dont seem to stress my hardware as much as other ones. (Not even close)

*I have wondered about this for a long time.  A 2 million poly model will cause heartburn for my machine, but I have made solidworks ecosystems with 1.5 billion and they work fine.  Does anyone know the reason for this? 

Sorry about going off the main thread topic.  I am using V5inf.
