Excuse for bad language, I transport an online translator. I test game for Iphone and for Ipad and I have 60-65 FPS. If I press the HOME button game is turned. If I press an icon game again it is started. After closing and opening game loses on 3 FPS. If I close and I will open game of 20 times game will have 15-20 FPS. That to do to me, help please.
