God, AMD needs to open source their Windows drivers. This shouldn't be faster in any sane universe. What it means is that the schmucks developing DXVK (largely a community freetime effort, aside of the work invested by companies like Valve who hire people to work on it) do so much better better job implementing DirectX 11 virtually, within Vulkan than AMD does implementing DirectX 11 natively, on bare hardware, that it runs faster even with the translation overhead.
