9Ex appears as the DDI version in DirectX Diagnostic Tool even though a video card supports DirectX 10 on a Windows Vista-based computer


You use a Windows Vista-based computer that has a video card that supports DirectX 10. When you click the Display tab in DirectX Diagnostic Tool, 9Ex appears as the Device Driver Interface (DDI) version. This problem occurs even though DirectX 10 appears as the DirectX version on the System tab.


You can safely ignore this problem. This problem does not affect the performance of the system graphics.
