DirectX 12 Makes Windows 7 Debut With Latest World of Warcraft Patch
In what is likely to create a good deal of controversy along with a few cheers, Blizzard will be adding DirectX 12 support to World of Warcraft on Windows 7 thanks to a bit of effort from Microsoft. You might be wondering how that is possible? Well after seeing massive performance gains in WoW when Blizzard released their DirectX 12 update for Windows 10 in late 2018, resulted in the company wanting to bring those performance improvements to gamers still holding out on Windows 7. To facilitate this, they began talking with Microsoft who after getting a great deal of feedback from Blizzard decided to act on it. To achieve this Microsoft decided to port the user mode D3D12 runtime to Windows 7, which will unblock developers, thereby allows them to take advantage of the latest improvements that the DirectX 12 API offers while still giving full support to customers on older operating systems.
For now, World of Warcraft is the first game to run in DirectX 12 on Windows 7 with the latest 8.1.5 patch. However, they will not be the last as more developers are working on porting DirectX 12 games to Windows 7 with more announcements to follow. Microsoft, of course, has taken it upon themselves to remind everyone that the best possible performance with DirectX 12 will still be had on Windows 10 due to numerous OS optimizations. How true this is remains to be seen, but for many curmudgeons still holding out on Windows 7, this will likely be seen as a form of vindication for sticking with the now venerable OS.

1.3 = Miracast support
2.0 = allows closer to the metal graphics programming
2.1 = HDR10 support
2.2 = VR and AR support
2.3 = perfdata query (standardized way to get GPU load, GPU frequency, memory frequency, etc.--which lead to the detailed GPU performance view in Task Manager)
2.4 = D3D12 hardware video decoding and more perfdata (fan speed, temperature, etc.)
2.5 = DXR support and HDR tweaks
None of these things will ever come to Windows 7 because the display drivers simply don't support it.
So the question remains if anyone knows, how do windows 7 users download dx12? Is it confirmed also if its not on windows 8.1? Answers pointing to google or other search are not valid.
...not to mention, microsoft has on a few occasions, mis-written the dxgi change list noting feature added under say, 2.4 that weren't added till 2.5.
Miracast was available to Windows 7 as WiDi (or more accurately, Miracast is the evolution of WiDi.)
HDR is present on 7 and 8 via vendor driver api's
VR and AR don't require DXGI, but an exposed framwork helps accelerate development
Perfdata query introduced compatibility regressions with other utilities that could do it first.
etc.
Now adding these to the DXGI ecosystem is useful, it brings things together under windows 10 more coherently, but it is not and will never be the only way to get things done.

...the reason why Vulkan gets a big boost on AMD cards is because the GPU is spending less time waiting for the driver running on the CPU.
4% can also be explained easily by driver differences (Windows 10 driver dev forked from Windows 7 driver dev a long time ago, optimizations for Doom 2016 may have been overwritten by optimizations for newer games released since then).Unified shaders were introduced in Direct3D 10/Vista.
In addition to post 1 (as @eidairaman1 mentioned), I also had already restated the issue clearly.

Is that it, I suppose you wouldn't like to elaborate on that or maybe not?
For emulation - no it's not incorrect.
Really, which part of that do you think I don't understand?
No, it's totally up to MS.devblogs.microsoft.com/directx/world-of-warcraft-uses-directx-12-running-on-windows-7/
