Remember that /Zp16 must be used setted

You don't need /Zp16 at all. The vector types are already set up with __declspec(align(16)) so they will get 16 byte aligned as local/global/static variables without any need for compiler flags. The only time you need to worry about alignment is on heap allocated data.
