Project Butter is a lot of work Google is putting into it’s Jelly bean system, and right now it’s involving a load of stuff to make our device much much better including:
- Triple Buffering
- Touch Responsiveness
VSync improves graphical perfomance
Triple Buffering is where Google have tripled the buffering, making animation really smooth as people will be able to see when we get some real footage.
Touch Responsiveness is improved thanks to some trickery is able to detect much better where the finger is.
All of this is coming to Android 4.1 Jellybean!
