Congratulations! more RAM is always good for speeding up workflow on complex scenes. The render looks very promising. Are you going to make an animation? One that shows the viewer the whole world you made? that would be really cool. BTW, my 680 million polygon count was 99% because of sym-lattices. So that's not to many primitives in there. Okay, still 5000 primitives, but they where from only one model and a few trees made out of boxes. The rest was all Sym-lattice and terrain work. The primitives only had like 400.000 poly's if I remember correctly. The onther 683 million where terrains and sym-lattices. It does get slow though when you merge everything together. Filesize over 1 GB. I saved it in multiple files though ranging from 38 to 536 MB.
