Game framerate drops really low until system restart - Launchhd?

So earlier this week I was playing World of Warcraft as I do normally. When all of a sudden my frame rate dropped. Thinking it was just a game issue I exited out and re open the game to find the frame rate still incredibly low. So thinking it might just be WoW I open another game (Dragon Age II) and it's FPS are also incredibly low. Normally in game FPS is around 30-45fps (all day, everyday) but when the problem happens it sits at around 10fps or lower and stays there. This problem typically occours 10-20mins after opening and playing the game. I also tried playing another game (Dragon Age II) and same thing happened with Frame Rate. If I restart the computer the games will run fine for a little bit and then it happens again. The reason I am so worried is that this has never happened before in the almost 2 years of owning my Macbook Pro. Thanks for the help in advance!

Problem 2

Also when I have nothing running but just finder I find in the Proccess's window a bunch of proccess's running inside an application called Launchhd.
