Hi~ I just built my terrain using quad trees. Everything was fine except the rendering step. When i reach each leaf of the quad tree, i built a mesh for it and rendered it. But that made the fps slower than rendering the whole terrain at once. Can anyone give me any suggestion how to do the redering step when i reached the leaf. Thank you~ ^__^

I''m using CopyMemory to copy all the data of the visible leafs into an big array wich contains all vertex-data wich is visible, so I only have to use one rendering call (but this only works with tri-lists)

You can create a dynamic vertex buffer, lock it every frame update, fill it with the visible nodes'' vertices, unlock it, render it.
