Windows 7 with the platform update supports only the WDDM 1.1 driver model and therefore, feature level 11.1 hardware support is not available (through the platform update). The Windows 8 WDDM 1.2 driver model supports a new generation of hardware, exposed through D3D feature level 11.1. See D3D11_FEATURE_DATA_D3D11_OPTIONS for more info about which features are emulated. This emulation is available on Windows 7 with the platform update. Several features, such as PSSetConstantBuffers1 with constant buffer offsets, require new drivers for feature level 10 and higher, but are actually emulated for feature level 9. Since there is no guarantee that these optional features are available, make sure your applications have appropriate fallback behaviors in the event that the desired functionality is unavailable. These updated driver versions, as well as most optional features exposed through CheckFeatureSupport, are unavailable on Windows 7. When reading the Direct3D11.1 documentation, understand that new drivers means WDDM 1.2 drivers. Windows 8 introduced the WDDM 1.2 driver model, which provided improvements across the associated API surface for all feature levels. Before using Direct3D11.1 on Windows 7, be familiar with these specifics: The features of these graphics components are tied directly to the graphics kernel components, graphics drivers, and graphics hardware.
