Transform Feedback
Transform feedback allows you to run geometry through the vertex shader and write the resulting vertices into a buffer. That buffer could then be used to re-submit the draw calls without going through the full vertex transforms again. This could be used to capture the positions of a GPU-driven particle system, or write out the results of mesh which was skinned on the GPU.
