Would it be inefficient to use, say a grid of 5x5 VBOs, for a patch of terrain over using one larger VBO containing the entire patch?
I used the grid so I can manage the LOD easier but I’m wondering if grouping everything together into one VBO would be worth the trouble. I currently get around 8 fps displaying 400,000 triangles at my maximum terrain resolution. This is on a fairly weak laptop with a Dual-Core 2.1GHz, ATI Mobility Radeon HD 4200 but I would think that I could get much better results.
