Previously it was determined that instancing was not needed because openGLs intermediate mode is way better than d3d’s intermediate mode, so normally it’s not needed.
But as instancing has grown beyond the use for simple quads in a particle system, instancing is now being conciderd even for openGL.

Maybe the shortsighted fools at the ARB should have paid attention when we said last year that instancing was for more than “quads in a particle system.”
Mmmm… yes, but my bet is that opengl instancing is more for GPGPU or GPU physics than for particle systems.
Basically it’s so that the data does not have to leave the GPU and pass trough the CPU.
