More trees with TreeIt

I have yet to try it with my own trees so I can't say for sure. I think the tree models I have are still too complex (5K polygons) with the LOD distance I would like to set (350m to avoid pop-in). I may have to reduce tree density, but I consider it a last resort. My goal is to create low-poly models ( <2K polygons) that look good enough, but I'm not quite there yet for all tree types. I'm working on it though :)

What type of performance increase with lets say bathurst? Ive noticed my gpu load jumps around ~20% when heading up the hill over the crest atm.
