Some NVIDIA D3D11 drivers are buggy and interprets the level passed to
GetDimensions as being relative to 0, rather than the SRV's MostDetailedMip.
This affects all integer texture formats because the dimensions are used for
sample position calculations on integer format textures, which leads to sampling
outside the texture when the base level is non-zero.
