D3d_feature_level

D3D_FEATURE_LEVEL is an enumerated type that defines a strict set of functionality supported by a graphics processing unit (GPU). Instead of checking for individual capabilities (like "does this card support tessellation?"), a developer can check for a specific feature level, such as D3D_FEATURE_LEVEL_11_0 .

In this example, the application asks for 11_1 first. If the card only supports 11_0 , that level is returned, and the app adapts accordingly. Best Practices for D3D_FEATURE_LEVEL d3d_feature_level
