There is no such thing as "the one true gaming graphics API"
Windows/Xbox uses Direct3D, Mac/iDevices use Metal, PlayStation uses GNM/GNMX, Nintendo Switch uses NVN.
Compared to DirectX, Vulkan is barely used at all in gaming, except on Linux and the most recent subset of Android devices.
If it weren't for Proton's DirectX emulation running on top on Vulkan, Vulkan would be largely irrelevant, from a "widely used in real world gaming" perspective.
