I would recommend downloading and running DDU to remove your current AMD driver. Restart the system, disable your antivirus temporarily and redownload and reinstall Crimson 16.9.1. Restart your system and check that the Vulkan runtime libraries are installed and appear in add/remove programs. Verify the Doom Cache in Steam and then try to launch the game.
I had exactly the same problem with my new RX 480. Tried every trick found on Google, but with no luck. There's one way. You need to install/reinstall Windows 10, coz with 8.1 it ain't working.
I have the same problem. After the chosen Vulkan API game does not start.
I performed all acts that suggested amdmatt. Nothing helped.
Windows 8.1 Pro
Xeon E3-1241 v.3
MSI H97 Gaming 3
MSI RX480 Gaming X 8G (Crimson 16.10.2)
16Gb RAM Crucial (2x8Gb)
Maybe there are some new solutions to this problem?
Install Windows 10 and enjoy
Just I do not want to do it... Vulkan should not work only on Windows 10. There must be some other solution...
I tried and failed. Hate Windows 10 too, but there's no other sollution.

Re: Doom does not work on Vulkan in Drivers & Software

Guys! I found the solution! The main problem in the registry! When installing drivers not prescribed path to the driver file in the registry.
The sequence of actions that helped me:
1. Uninstalling all Crimson drivers Using DDU;
2. Deleting folders: C:\Program Files (x86)\VulkanRT;
3. Install the latest Crimson drivers (In my case it 16.11.3);
4. Go to the registry: HKLM\SOFTWARE\Khronos\Vulkan. There should be a section "Driver", which in my case there was no.
You must create it. Then, in this section creates a Key DWORD "C:\Windows\System32\amd-vulkan64.json"
Now everything should work!
P.S. Sorry for my bad English. I hope I could help you.
