ID3D11Device::CreateTexture2D
Texture2D resources have limits on their width and height that differ across feature levels. In feature levels 9_3, the following are guaranteed minima, and individual implementations may exceed the requirements.
| Feature Level | If MipCount > 1, Dimensions must be integral power of two | Minimum supported texture dimension | Cube textures dimensions must be power of two | If MISC_TEXTURECUBE is set, the ArraySize is: | If MISC_TEXTURECUBE is not set, the ArraySize is. |
|---|---|---|---|---|---|

| D3D_FEATURE_LEVEL_9_2 | Yes | 2048 | Yes | 6 | 1 |
| D3D_FEATURE_LEVEL_9_3 | Yes | 4096 | Yes | 6 | 1 |
In the previous table, the full name of MISC_TEXTURECUBE is D3D11_RESOURCE_MISC_TEXTURECUBE.
The following are true for all 9_* feature levels:
- When using D3D11_USAGE_DEFAULT or D3D11_USAGE_IMMUTABLE, BindFlags cannot be zero.
- When using D3D11_BIND_DEPTH_STENCIL, MipLevels must be 1.
- 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.

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 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. ${REMOVE}$ |
