I havent heard of the game, but the easiest ways to improve performance is to lower the resolution, try it out in windowed mode, close background apps, use lowest settings for graphics and try to clear out any idle programs, but aside from that I wouldn't trust any apps or boosters that supposedly speed up your pc.
I have a crappy laptop as well, usually lowering graphics and removing enhancements helps alot, so much so that I don't use windowed mode, so try it out.
