We need to know the exact model of CPU you have, and as Dave said, the rest of your rig's specs. Being the fact that you're using mobile graphics, 60 FPS is highly unlikely.
Well, the rest of your system seems perfectly well equipped to run BF4 on Ultra at 60, with the only limitation being the Graphics Card. Unfortunately, laptops are pretty much screwed in this aspect due to how large and unwieldy VC's are, even lower end cards. Out of a 755M, I'd honestly expect maybe 30-40 FPS on Low to Medium, You'd need at least about a 760 (Desktop) to get over 60 on Ultra.
