This new update causes lag

I love MCPE, its a great game for when you cant be at your computer to play, and all was great until this update. About 10 minutes in to game play (on a 7+) it stutters and has lag, as well as some noticeable FPS drops. Ive tweaked the render distance, but there are the same results each time. Please fix this.
