If none, then maybe we still haven't seen what Instancing is capable of. Maybe with more time, Crytek could make all the vegetation in Far Cry instanced.
it should be pointed that this is just a quick patch .. made to a game that is already finished.. there can be a huge diference between a game optimized from the ground up for SM3.0 ,than a PS1.x/P2x game which add Sm3.0 improvements here or there..
Geometry Intancing alone fully implemented in every geometry can show 2x times the performance than not using it.Nvidia have an asteroids demo where they can render twice the polygons for the same Fps.. just using G.I.
as other pointed the best gains in performance are exactly in the places where more work in done.. Scenes with many lights can be done in just 1 pass.. and there you get huge performances benefits.
FOrest with G.I will also show great benefits. G.I can be very powerfull for Crowded scenes with many soldiers ,FOrest or for FLight simulators to add more detail to the terrain which is lots more polygons and objects in a scene.
