MacBook Pro gets Really hot on medium settings

I have just recently bought a new MacBook Pro. It has a 5500M graphics card and a 2.3 i9 processor in it. When playing the game my laptop will get very very hot. This MacBook has better specs (especially the processor) than my old laptop, and it could run the game on ultra and barely got warm. Any ideas?

Is Vsync enabled? If not try to enable it.
