Has anyone used this extension as a performance improvement? I belive it is a 1.4 enhancement, althought I don't know how many drivers support it. It sounds like an excellent way to cache some models in high speed memory.
It's the long-awaited replacement for both NV_vertex_array_range and ATI_vertex_buffer_object. It should be used preferentially over all other vertex drawing methods. However it exists on < 0.001% of PCs right now, and won't really catch on for another 2-3 years.
