Uh then why are so many other reviews moving over to DX12 and Vulkan testing? Less and less people use DX11.
Are you serious? The vast majority of titles today are still DX11 primarily. DX12 is still mostly an afterthought for most developers, hence the lackluster performance. Only Gears 4 is the purest example of a DX12 game, as it was built from the ground up to use DX12.
EDIT: I'm seeing higher framerates for
DX12 here.
And, that Hardware Canucks review tests both DX12 and DX11, and Deus ex: MD is faster in DX12. As we all expected.
For the Radeons it's faster, and only barely at that. For NVidia, it's about even or slower.. At any rate, I wouldn't call Deus Ex MD a good example of what DX12 can offer. It's fair, but definitely not in the same class as Gears of War 4 or Ashes of the Singularity.
When you say Nvidia will get this, what do you mean? Will Nvidia themselves patch their drivers to make them perform better? Or does ID have to do the work?
It has to be implemented by Khronos group, of which NVidia is a part of. AMD got it first because the consoles are already using GCN hardware, so it was easier to implement. Also, Vulkan is a direct derivative of Mantle. NVidia already supports shader intrinsic functions and has for a long time, but it needs to be exposed through NVAPI or CUDA. That's partly why certain engines or games run so fast in DX11 mode on NVidia. Engines like Frostbite 3 and Unreal Engine 4 use NVAPI, which can seriously enhance performance..
