I would recommend upgrading to a better card.
It's a laptop. Upgrading a video card is not possible (feasible).
Mr. Rody, I would recommend trading it in for a laptop that is better suited to gaming.
my problem is that
i can not run any game like bf3 or assassin creed and the geme is very slow and the soldier in bf3 get lag
I'm afraid you will need to lower your in-game graphic settings and resolution, to be able to play the game without much lag.
