I have been reading a lot of debate on a new feature that will be available in the new version of the game engine Unity 5.4 - called GPU instancing. I understand the importance of instancing in general, both in terms of saving memory and draw calls.
However, even after doing some reading, I still couldn't understand what exactly are the differences between GPU instancing and non-GPU instancing - and, more importantly, where the alleged GPU advantages in terms of performance come from in comparison to standard instancing.
Thanks for your knowledge and for any references.
