Can't play battlefield 3 on my lenovo y510p smoothly?

So i just bought a Lenovo y510p. And i can't play battlefield 3 on online smoothly with just 20-23 fps on lowest setting on 800x600 resolution. I can play assassin's creed 4 with 40-50fps on a high setting so I can't see where the problem is

They are on different engines and coded differently so the games will act differently, ex: Source Engine i get 60 fps, but on the Unreal Engine i get 20-30 fps. But with the pc you have you should be able to run bf3 at 30-60 fps.

update the drivers and directX, defrag the hard drive and clear temp. Files that may fix it
