Apps aren't going to help you increase FPS, all they do is turn off processes you could do by yourself in task manager, while running in the background and mostly likely hindering fps. When gaming make sure to have close any apps you aren't using and then go into your processes and do the same. And like Phoenix said decrease graphics setting in game, things like motion blur or anti aliasing being off or on the lowest setting usually increase fps.
