I suggest you restart your device and see if it is more responsive.
I suggest you restart your device and see if it is more responsive. I personnally did not feel any difference in my games applications.
Turns out the game was just chewing up CPU. When the iPhone is running at load, the touch performance goes down, making it seem sticky and less responsive. I've tuned the app and it now works the same on all the machines.
