If you go to the link above, that image has 18 million polygons, mostly with the trees... It took me 2 hours to render 8 1/2 by 11 at 300 dpi in final setting on a 500 mz machine with 256 megs of ram... However, I have other scenes that don't even approach a million poly's and it took me 5 hours to render at much smaller resolutions... So, there really isn't any rhyme or reasons and polygons alone are not what are going to make Vue keel over... :)
