Can you please explain how this works ? Having multiple draw threads that call display lists ? Barriers/Mutices needed ? What gain is to be expected ? Without knowing details I guess the speedup will be low and only noticeable for draw trees with lots of geometry nodes. Or could you compile several glsl shaders at the same time (guess this happens on the cpu part of the OpenGL driver) ?
