Vista upgrades may be slowed by graphics

The biggest barrier to users upgrading existing PCs to Windows Vista will be the new operating system's graphics requirements, analysts agree.
Microsoft has designed Aero so that it scales to the graphics capability of the PC. According to information it's released to partners in a Vista Product Guide and posted on its "Vista Capable PC Hardware Guidelines" Web site, Aero will require a video adapter that supports WDDM (Windows Display Driver Model) video drivers and DirectX 9; it must also have a graphics memory bandwidth of at least 1,800MB per second.
