I'm creating a msaa depth buffer with D3D11_CENTER_MULTISAMPLE_PATTERN, then rendering to it without a pixel shader/render target. I expect the depth to be sampled at the pixel centers but it appears to be still using the standard sample patterns. This is different from the reference driver and (as far as I can tell) the D3D spec.
Is CENTER_MULTISAMPLE_PATTERN supported? Am I mis-interpreting its specified behaviour? Is there some implementation sublety I'm neglecting?
(I have a test app/source I can provide if helpful.)
