Intel graphic card or Intel HD is a graphic processor that is integrated in your CPU. These graphic card processors are fairly weak when it comes to gaming. The thing that you can do to improve the performance is to keep the driver up to date. Any third party booster tools will have no effect. However, if you don't have any other option and you want to play games on you computer (using your Intel HD), I suggest you lower the details and the screen resolution of the game.
