Version Numbers for WDDM Drivers

To ensure that a display driver that conforms to the Windows Display Driver Model (WDDM) or the Windows 2000 display driver model (XDDM) runs on Microsoft Windows with a specific version of Microsoft DirectX, you must apply an appropriate version number to that driver. If a vendor distributes a display driver with the wrong version number or a version number that uses the wrong format, end users will encounter difficulties when they install any DirectX application.

Note   The DriverVer directive provides a way to add version information for the driver package, including the driver file and the INF file itself, to the INF file. By using the DriverVer directive, you can safely and definitively replace driver packages by future versions of the same package. For more information about this directive, see INF DriverVer Directive.

This table gives examples of the range of version numbers that are appropriate for vendor-supplied display drivers that conform to WDDM for compatibility with various versions of DirectX. \

This table gives the range of version numbers that are appropriate for vendor-supplied display drivers that conform to the Windows 2000 display driver model for compatibility with DirectX 9.0.
