I thought DX 12 did what op is suggesting amd is doing. With DX 12 u get all those things so why bring it up as a amd thing? Unless I'm mistaken.
Maybe they do 1 on nvidia cards but can't see amd cards do more at current or past gen cards as its a DX issue not hardware issue. All this will be unlocked with dx12. AFAIK at least.
It is an AMD PR piece.
