IsShaderJobCacheDDCEnabled()

bool IsShaderJobCacheDDCEnabled

(

ShouldCompileODSCOnlyShaders()

bool ShouldCompileODSCOnlyShaders

(

)

Returns true if we should compile shaders that are only compiled in on demand shader compilation modes and not stored in cooked shader maps. This can be useful for debug shaders.
