DirectX 11.1: Current graphics chips are not completely compatible 

Current Cayman graphics chips on HD 6900 graphics cards will not support all the features of DirectX 11.1.

Also pointed out the AMD employees that DirectX 11.1 for mobile devices that need to be very economical, offering several improvements, including new 16-bit image formats (DirectX Surface format). This need, compared to 24-bit formats use less memory and data transfer rate and can even reduce the power consumption of mobile devices in weak. 

Also be considered as an important innovation in the AMD at the unordered Access Views (UAV): These are general data buffer that can be read simultaneously and described for Compute and pixel shaders, and were introduced with DirectX 11. DirectX 11.1 Shader may all stages (vertex, Hull, domain, geometry) to access the UAVs. This increases flexibility in the integration of GPU compute calculations during rendering of 3D graphics. In the context switching, however, these changes have no effect. Nvidia did not comment on request for DirectX 11.1-topic and pointed to a disclosure agreement with Microsoft.
