You are both CPU and video card bound. The Intel video chip is a very low end video card.
In order to have any chance of playing with a decent level of performance you will need to do the following:
In the games "Video Settings"
1) Set the "Maximum Texture Size" to 128.
2) Set the resolutiuon to 1024x768, or lower.
3) Make sure the anti-aliasing slider is all th way to the left.
In the game under Options->Graphic Detail->Advanced.
1) Uncheck all but "Bump Mapping" and "Detailed Water".
You also need to make sure you have the latest video card driver from Intel.
