Hi

Which optimizations have you already implemented? Actually, when a VBO is too big, the performance can decrease a lot, look at GL_MAX_ELEMENTS_VERTICES and GL_MAX_ELEMENTS_INDICES. I think about using several layers of cache (GPU, CPU, disk) but it's good to display very large meshes, I'm not sure it would be faster in your case.
