Yes, Im using ecosystems. Basically its a pretty wide shot.  Imagine a tropical valley (Im up to 23,000,000,000 polygons) with mountain range in background (I will post image soon)...

Im using very small scale....and its using alot of instances to fill the jungle canopy...(93% coverage)

Are you using ecosystems? I can build ecosystems with the Scots Pine (100-150K polygons) on a 5 years old 1GB computer!
