similarly when there’s some simple arithmetic I can’t mentally calculate I use a cloud based coal powered statistical word generator because I don’t realize that there are existing dedicated tools for the job and it’s easier for me to defecate my stream of consciousness into a chat window than to take my eyes off vertical infinite scrolling video long enough to take basic troubleshooting steps
Vulkan isn’t magic, its power comes from the flexibility it gives developers in its API. If developers are using DirectX, especially older versions, then they’re not utilizing that flexibility.
If DirectX code performs better through a Vulkan translation layer than on Windows, it means the driver implementations or OS bloat are what’s causing it.
With your theory, you could run a DirectX to Vulkan translation layer on Windows and also get increased performance. Which may be true, but once again points the finger at bad drivers.
