Why the stutter?

I loved the game at first. Ran smoothly. Then each day the first game had stuttering (stops starts, hesitations)that made it almost impossible to get past 10-which screws with the average. The second game would run smoothly. Now it stutters on the first two or three games before the ball runs smoothly. Deleting and reinstalling helped for a while.
