Direct3D 11 on Downlevel Hardware
This section discusses how Direct3D 11 is designed to support both new and existing hardware, from DirectX 9 to DirectX 11.
This diagram shows how Direct3D 11 supports new and existing hardware.
With Direct3D 11, a new paradigm is introduced called feature levels. A feature level is a well defined set of GPU functionality. Using a feature level, you can target a Direct3D application to run on a downlevel version of Direct3D hardware.
