Using Shader Model 6 shaders for DirectX Tool Kitīy default shaders are built with FXC for Shader Model 5.1 (using Root Signature 1.1). Shader Model 6 was not supported prior to Windows 10 Anniversary Update (14393). The code above assumes you are building with Windows 10 SDK (14393) or later.

Note that a number of Shader Model levels were defined originally as 'experimental' so were not supported by the released DXC compiler or production drivers until later releases of Windows.
