Ummmm.. If Crysis2 runs on Ultra, then there's no excuse for CPU to NOT to run the game on max settings. The recommended requisites say it needs a core 2 quad.
Well even a laptop's core i7 is faster than the former. I'll bet the game runs nicely on your laptop.
If it does, do me favor and choose me as the best answerer because I damn sure that the game will run on your laptop
