Did I understand it right if the real claim is that the per-mesh CPU setup cost in Metal is 1/10th that of OpenGL on iOS Touch devices?
So, things like fill rate, shader complexity, etc, are largely unaffected?

Metal works on A7 devices (iPhone 5s, iPad Air) only.
You are right that fillrate, shader complexsity, etc doesn’t change; it only removes the OpenGL driver overhead, which gets reflected as CPU render time (it’s still the same GPU!).
