Not exactly support. but bit of both!

If you don't want to upgrade to Windows 10 yet, you can probably hold out a few months until the new Vulkan API is released, which should work down to Windows 7 or so, as long as you have a OpenGL 4.* compatible graphics card and your graphics card manufacturer releases new drivers for it.

On that note, there's a Vulkan press conference on the 21st January, so it will be date, when we'll likely get the release date or the specifications released.

I managed to get to windows 10 with no faults this time around. DX 12 running sweet and sound with no bugs yet, terraria and Jet set are going okay for me.

Thank you for helping, And I am sure I will be able to bug test for you guys soon too.
Being on a gtx 860 4bg with an octacore i7 it's alright for emulation
