Do you need to call CoInitialize() when using Direct3D9?
My understanding was since D3D is u开发者_如何转开发sing COM, the answer is yes. But in the Ogre rendering engine, it appears this is never called. Is this fine or an oversight - if so could it have some actual consequences?
It is not. You don't use CoCreateInstance(), the interface types are not declared in IDL, you have to link to a .lib
