AMDVLK Still Has Some Performance Advantages Over Mesa's Radeon RADV Vulkan Driver, But It's A Good Fight

Sounds like you are using pro not vlk

I extracted the json and icd files from the amdvlk github repo precompiled Deb for Ubuntu.
As far as I know tho, the amdvlk json and icd files are the same used in the pro driver, only older versions and with a longer update interval between versions.
