title: Andengine low FPS on certain phones
body: <p>My game runs well on most phones (56 FPS), but others run the game at ~25 FPS. In my game I have 3 particle systems and as far as I can tell the problem comes from here. My question: Is it a good idea to stop spawning particles if I detect FPS lower than, let's say 30? An if the FPS is higher just run normally. I'm not sure if this can cause any problems. Is there any other solution?</p>
