Improve OpenGL Performance By Using GPU Addresses
NVIDIA has published a presentation about new techniques that allow to decrease CPU L2 cache misses due to vertex array pointers dereferences and object bindings.
The GL_NV_vertex_buffer_unified_memory and GL_NV_shader_buffer_load extensions allows to use GPU addresses directly to specify vertex attrib, element array or buffer object. Measurements have shown that these techniques can result in more than 7x speedup!
