Directx 12

[Archimedes]

Take a look at this: http://youtu.be/RUCn_rvDU-A?t=7m18s

What that guy basically says is that DX 12 will be 50% faster that DX 11. Of course there might be some details that I'm completely ignoring regarding this speed up and what it actually implies, but still, it's something. I'm just wondering if this will impact at all PPSSPP or other emulators like Dolphin, performance wise, when run under DirectX. What do you guys think?

No he says "can be up to 50% faster" and specifically for CPU bound applications. While emulators are often CPU-bound they often don't use all cores and modern OpenGL implementations (and I assume Direct3D although I don't know) are somewhat asynchronous (with some sequence points of course).

Could you see some improvements? Yes. Will you see a magical 50% performance increase that can not be ported to DX11/OpenGL? I very much doubt it.
