Question about Windows XP support

I have a question about Windows XP support.
My question is why not also add support for DirectX 9? I know Unreal Engine 4 uses DirectX 11 render but why not add support for DirectX 9 as well? What about Windows XP 64-bit?

I remember Tim using the 64 bit version of Windows XP when it first came out, and my recollection of it and its driver support was that it was experimental at best That was a long long time ago and maybe things have changed, however AFAICT the vast majority of people still using Windows XP are using the 32 bit version.

With regard to DX9 support – we’re keeping the option open to add it down the road if absolutely needed on Windows XP, however only supporting OpenGL on Windows XP for now allows us to focus resources on more forward looking features and platforms.

I believe the version of OpenGL supported on Windows XP exposes more features than DirectX 9 does (I’m not a rendering guy), so that’s a nice side benefit. The main reason we would want to add support for DirectX 9 for is in case there are a ton of of driver compatibility issues with OpenGL and Windows XP.
