Crysis 2 low fps on pretty good laptop

Hi, i just played Crysis 2 on this laptop:
Asus x52j series
Intel core i5 460M @ 2,5 ghz
6gb Ram
and it got 2 graphic cards:
1st – integrated Intel HD Graphic (i run CPU-Z to check how much memory and it says 1gb)
2nd – nvidia GF 310M ( also 1gb memory)
Win 7 Home Edition, DirectX 11
I thought this will easily run Crysis 2 on at least medium settings. But game has very low FPS , something beetwen 15-30 fps. I know that only one card is running at the moment. Even on very low setting its still the same.
Does this graphic card is to weak? Or maybe DX 11 is the problem ?
