Hey there!
I have noticed there are two new upcomming extensions for WebGL, WEBGL_multi_draw and WEBGL_multi_draw_instanced.
So the question is, can we get some benefits here in Construct? ;-) The implementation is not stable yet, so I guess it will take some time, but it shouldn't take long.

I reviewed this and I don't believe it applies to Construct. It looks like an optimisation that might be useful for 3D engines, but Construct uses a 2D rendering approach.

as Ashley said, that project you found was meant for a 3d map script > CelsiumJs
not really a 2d enhancer, even though might be adapted to 2d since it's meant for boosting javascript renderer blocks, which C3 might use now if im not mistaken.
