Introduction: Hacks #68-74

Except for the CPU and memory, the video card handles more data more often than any other component in your PC. It’s possible for a 1024768 display with a color depth of 32 bits (4 bytes) refreshed 60 times per second to move tens of megabytes per second—if the entire screen refreshed with new data at each screen refresh interval. This is a lot of data, and it does not include the processing and rendering the video card’s CPU has to handle to generate a constantly dynamic display. Enhancing video performance is most important to graphic designers and gamers, but it can also make Windows less sluggish and clunky for the rest of us.

Overall video performance is affected not only by the speed, quality, and features of the video adapter card (which in some cases you may overclock just as you can your CPU and system RAM) but also by which I/O interface your video adapter uses—ISA, PCI, or AGP (including video adapters built onto the system board).
