Symptoms

Consider the following scenario:

You have a system with 1GB or greater of Video memory, and 4GB or greater of system memory (RAM).

You run the Direct-X Diagnostics tool, and it reports that you have an unexpectedly low amount of Approximate Total Memory on the display tab.

You may also see issues with some games or applications not allowing you to select the highest detail settings.

Cause

The API that DXDiag uses to approximate the system memory was not designed to handle systems in this configuration

Resolution

Microsoft is working to resolve this in future releases
