im bottlenecked by QuadTreeNode.Render... what is it?

i Would just like to know how to lower the time taken to do what ever QuadTreeNode.Render is … as it takes up 14ms on the GPU .

It seems that Quadtreenode is some kind of reference to the LOD system that the terrain uses… and so i do not see a way around this other than using smaller terrains and having them next to each other

split and stream
