Good game but burns my mac

This is a massive game with lot of hd graphics which my Mac book pro (with i7) just can not handle. Everytime this game starts mac gets heated up and evrything starts hanging. This game does not even run smoothly on lowest of the graphic levels, making it literally unplayable. I had eagerly waited for Trine 2 after Trine 1, but I am not able to play it at all. As much as I like Trine 1 because it is light weight and smooth, I do not like Trine 2 because it is massive and consumes a lot of memory.
