if can help,sometimes,for some games,if you close all apps running in the background,and reboot you're devices not help,for me ( only on some game)and after do a backup of you're data(savegames) disinstall,then reinstall some games(better with iTunes) solve some problems,of lags,stability issues,a fresh download directly on iOS 7 helps me,iPhone 5,iOS 7.0.4..
