  • When using D3D11_BIND_SHADER_RESOURCE, SampleDesc.Count must be 1.
  • When using D3D11_BIND_PRESENT, resource cannot have D3D11_BIND_SHADER_RESOURCE.
  • When using D3D10_DDI_RESOURCE_MISC_SHARED, Format cannot be DXGI_FORMAT_R8G8B8A8_UNORM or DXGI_FORMAT_R8G8B8A8_UNORM_SRGB.

D3D_FEATURE_LEVEL_9_1 256 Yes
D3D_FEATURE_LEVEL_9_2 512 Yes

D3D_FEATURE_LEVEL_9_2 Must use vs_4_0_level_9_1
D3D_FEATURE_LEVEL_9_3 Must use vs_4_0_level_9_3 or vs_4_0_level_9_1

ID3D11Device::OpenSharedResource

Feature Level Behavior Differences
D3D_FEATURE_LEVEL_9_1 Use ID3D11Device::CheckFeatureSupport with the D3D11_FEATURE_FORMAT_SUPPORT2 value and the D3D11_FEATURE_DATA_FORMAT_SUPPORT2 structure to determine if a format can be shared. If the format can be shared, CheckFeatureSupport returns the D3D11_FORMAT_SUPPORT2_SHAREABLE flag.
[!Note]
[DXGI_FORMAT_R8G8B8A8_UNORM](https://msdn.microsoft.com/library/windows/desktop/bb173059) and DXGI_FORMAT_R8G8B8A8_UNORM_SRGB are never shareable when using feature level 9, even if the device indicates optional feature support for D3D11_FORMAT_SUPPORT_SHAREABLE. Attempting to create shared resources with DXGI formats DXGI_FORMAT_R8G8B8A8_UNORM and DXGI_FORMAT_R8G8B8A8_UNORM_SRGB will always fail unless the feature level is 10_0 or higher.
