I'm using some simple physics in a game, that basically involves some gravity and one projectile being shot at some targets. Yet for some reason, the game requires heavy use of the CPU of a laptop processor (30-90%). This is true even when everything is still and nothing is being shot! It works fine on a laptop but becomes slow on a tablet or phone. Is there some way to get better performance?
The GPU process and the open tab in Chrome can each take up 15% of the CPU, though it goes down if nothing has happened for a while.
