3D Acceleration
Most people don’t know that they need 3D acceleration to play games properly. This acceleration is provided by a special card that plugs into a AGP or PCI-E slot and performs the extremely complex calculations needed to render the gorgeous graphics and effects you see in the game.
Some cards are so complex that they do pixel shading and other calculations that are simply beyond the scope of the processor. The card clears up the load on the processor which can then do basic tasks better and make the game run properly.
