A graphics card is a a computer component with its own memory and graphics processing unit which allows the computer to display high demand graphics. Some computers contain integrated graphics processing, which means there is no graphics card that is distinct from the motherboard. Computers with built in graphics cards are generally much worse at handling complex graphics; a dedicated graphics card should be used when attempting to play games with high graphic requirements. In either case, running updated drivers on your graphics card will optimize its performance.
Identify your graphics card. To do this, go to the control panel, and then click on the "Device Manager." Under your device list, look for the "Display Adapters" category, which will list your graphics card. You can click on your card for further information, such as the currently installed driver information.
