How odd, why is that caused?
Viewing post in Improved fragment/compute shading rates comments
My understanding is that it's due to incomplete Vulkan driver implementations. I have an old laptop that has an Intel integrated (non-discrete) GPU and when my code requests the fragment shading rate extension with logical device creation, Vulkan reports that the extension is unsupported.
P.S. Same laptop doesn't support GLSL uint64 nor float64.
