    DX 12   What AMD, Intel, and Nvidia do and don’t deliver




      Windows 10 is rolling out and the question of DirectX compatibility is going to move from a marketing bullet point to a tangible issue for users. For more than a year, AMD and Nvidia have been advertising that various older GPU families would support DirectX 12 at launch. Recently, however, there’s been some confusion over what level of support Intel, AMD, and Nvidia will offer for the new API and which products will run the upcoming games that rely on it. The current confusion seems to have been caused by comments from AMD’s Robert Hallock, who acknowledged that the various AMD GCN-class GPUs support different feature levels of DirectX 12. This has been spun into allegations that AMD doesn’t support “full” DirectX 12. In reality, Intel, Nvidia, and AMD all support DirectX 12 at various feature levels, and no GPU on the market today supports every single optional DirectX 12 capability.

          By the same token many card won't fully support DX11 then either. Devs will take the least common denominator (ie consoles). That's a good place to start.

          Extra features are only useful if people use them.

            Well, the Xbox One and PS4 are DirectX 12 capable consoles, but the problem is that most of the benefits about DirectX 12 come from CPU limited situations, such as consoles and current horrid (in comparison to Intel) AMD processors (which should change with Zen). You take a current i7 and a Fury X or 980ti, and it's not going to matter if it's running on DirectX 11 or 12, it's not going to make a difference. You take an APU in a console, then yea, it's going to matter, and that's what Microsoft is hoping for because it went cheap with its RAM and it can't handle 1920x1080 content.


            And then there's two little words which break whole reason for high frame rates: Adaptive Sync. Be it AMDs FreeSync or nVidia's $200 G-Sync, they're much more important than the 144hz panel marketing hype. And let us remember, there are still 0 PC games which use DirectX 12.
