Sounds to me like most of you are using the integrated Intel graphics chip set. This is not really intended for gaming, I'm sorry to say.

Yes, you can run the game, but it's not a dedicated graphics card, like the ATI Mobilty Radeon, or other dedicated graphics cards. The dedicated cards have more ram, have much better cooling, and are generally better all around for gaming, or other procesess that needs heavy graphic rendering.

It might be someting has changed in the graphics code with S 7, but hopefully this will get fixed by Cryptic...

I hope this helps...
