I have a mobile game that uses touch input, however I haven’ t coded any touch code yet. There is a noticeable frame-rate drop or lag for first time you touch the screen. It doesn’t matter where you touch. After that first touch, every subsequent touch is smooth as butter. What gives?
I am developing on Android Galaxy S4. Here are the first profiler stats after I touched the screen. These Two profiler stats are from TWO SEPARATE instances of the game.
