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.
The 10Level9 Reference section lists the differences between how various ID3D11Device and ID3D11DeviceContext methods behave at various 10Level9 feature levels.
