I have a Toshiba laptop that is only a few years old and I spent all the time downloading and installing diablo 3 on my comp last night only to find out that my video card is out of date!

my video card is Mobile Intel(R) 4 Series Express Chipset Family

does anyone know of a way to either down grade the game options, or upgrade a laptop video card so that the game will run on my system?

any help or advice would be appreciated!
