This method is not supported by DXGI 1.0, which shipped in Windows Vista and Windows Server 2008. DXGI 1.1 support is required, which is available on Windows 7, Windows Server 2008 R2, and as an update to Windows Vista with Service Pack 2 (SP2) (KB 971644) and Windows Server 2008 (KB 971512).
Frame latency is the number of frames that are allowed to be stored in a queue before submission for rendering. Latency is often used to control how the CPU chooses between responding to user input and frames that are in the render queue. It is often beneficial for applications that have no user input (for example, video playback) to queue more than 3 frames of data.
Windows Phone 8: This API is supported.
