--- Comment #8 from Rafał Mużyło galtgendo@o2.pl --- Given that as clear 'not implemented' messages as the one that comes here without native d3dcompiler_47 are often the very reason for crashes (especially within the d3dx9/d3dcompiler set), 'strongly implied' would be putting it lightly, especially if you already suggested that in the original bug.
