Shader Model 6.2 is a superset ofShader Model 6.1.

The main additions are as follows:

• 16 Bit Scalar Types. As opposed to minfloat16, min16int, and min16uint, these values can be used with memory operations (that is, reading and writing via resources or groupshared memory). Drivers are not required to implement this feature for SM6.2.
• Denorm Mode. This allows a shader to select the behavior with respect to denormal values: preserv them, flush them to zero, or pick the platform's preferred behavior (typically the most performant).
