DirectX Graphics Infrastructure (DXGI) [1] is a user-mode component of Microsoft Windows (for Windows Vista and above) which provides a mapping between particular graphics APIs such as Direct3D 10.0 and above (known in DXGI parlance as producers) and the graphics kernel, which in turn interfaces with the user-mode Windows Display Driver Model driver.
