When you bind the constant buffer to the pipeline (for example, via <a href="https://docs.microsoft.com/windows/desktop/api/d3d11/nf-d3d11-id3d11devicecontext-pssetconstantbuffers">PSSetConstantBuffers</a> or <a href="https://docs.microsoft.com/windows/desktop/api/d3d11_1/nf-d3d11_1-id3d11devicecontext1-pssetconstantbuffers1">PSSetConstantBuffers1</a>),
you can define a range of the buffer that the shader can access that fits within the 4096 constant limit.

The Direct3D 11.1 runtime (available in Windows 8 and later operating systems) emulates this feature for [feature level](/windows/win32/direct3d11/overviews-direct3d-11-devices-downlevel-intro) 9.1, 9.2, and 9.3; therefore, this feature is supported for feature level 9.1, 9.2, and 9.3.

On existing drivers that are implemented to feature level 10 and higher, a call to <b>CreateBuffer</b> to request a constant buffer that is larger than 4096 fails.

On runtimes older than Direct3D 11.1, a call to **CreateBuffer** to request a constant buffer that is larger than 4096 fails.
