I tried to apply this plugin on my existing project and I can confirm that FPS are always at 60 and there's a lesser CPU usage. This is only a workaround at the moment, so I can't reccomend to use it but could be a huge start point for high performance iOS games. iOS8 is installed on 56% of devices at the moment (https://developer.apple.com/support/appstore/) in my humble opinion, due to a jailbreak not available. But now, a JB was released so I think that this 56% will increase early.
