Windows Vista FAQ 1. What is the Windows Experience Index?
. This built-in performance analyzer is found in the Control Panel under Performance Information and Tools. Your Windows Experience Index is the lowest of five scores assigned to your system’s CPU, memory, basic graphics capability, 3D graphics power, and hard disk speed. Microsoft hopes that the Windows Experience Index will replace the lengthier enumeration of system requirements found on software boxes. Instead of reading that a game requires at least 1GB of RAM, a Pixel Shader 2.0 graphics board, and a 2-GHz CPU, for example, you’d see that a game requires a WEI score of, say, 3.2 or better.
