Unfortunately as I have pointed out in the past, not all chipsets are created equally, I have seen one device with a tegra 2 run at a solid 60 while another with a tegra 2 run at 30 (right now due to our engine restraints those are the only two options really, 30 or 60 fps). The differences lay in the drivers built by the manufacturers, size of the screen (fill rate is a huge issue on Android), and also screen type may make it look like its running faster or slower (refresh rate, etc). An amoled screen for instance seems to display fast moving objects much better than other types of screens due to its refresh rate. For example the tablet I bought (galaxy tab 10.1) runs the game at 30 but the screen type makes the ball look ghosty, something that has bothered me from day 1. For this device its the massive amount of pixels involved that slow it down.That being said closing everything that is running in the back ground, turning off the hud, and in some extreme cases a restart seem to help. We are working on putting an advanced screen in to tweak optimizations for the near future to help people out. These would include lowering textures, not drawing the environment, and anything else I can think of that might squeeze a little more out of the GPU thread.
