This may sound silly to some, I have no proof. But the problem exists if you do a Google search. I can't remember which game it was now, Crysis 3, Far Cry 3? Anyway, which ever game it was I installed it on my SSD it had some lag/stutter. Couldn't figure out what the problem was, my specs should handle the game perfectly fine on near or at highest settings.
Anyway, I installed it on my HD instead and there was no lag/stutter. Just slower loading times. Whatever the problem was I have no idea.
