I know OpenGL is still used, but it's not used much for performance intensive applications like AAA video games, it's used for things like desktop compositors, largely because the spec hasn't been improved or changed since 2014. Maybe Zink is uniquely inefficient, but my frame of reference for how fast these translation layers can be is DXVK, which in some cases is even faster than native when translating DX11 to Vulkan.
