On both my iPad mini 4 and my iPhone 6, the OS seems a lot smoother on iOS 9.3, but games like Zig Zag have these annoying micro-stutters which make the games impossible to play (due to needing precise timing to play). Zig Zag used to run flawlessly on both devices and now it stutters. I'm restoring back to 9.2.1 to hopefully eliminate this big of lag. I've already tried deleting the game and reinstalling it as well as closing ALL other apps and restarting. I just cannot get rid of this stutter.
