Greetings!
Vulkan, as an option, is missing in my Renderer List.
Here are my specs:

Things I have tried:
- Uninstalling display drivers using DDU, then installing the latest update (391.35 for my GPU)
- Adding a REG_DWORD in HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\Vulkan\Drivers whose name is the path for the latest nv-vk64.json file located in C:\Windows\System32\DriverStore\FileRepository\nvddi.inf_amd64_8bbe140e99a054e8, with a value of 0
- Adding a REG_DWORD in HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\Vulkan\Drivers whose name is the path being asked in vulkaninfo.exe's output, with a value of 0
- Uninstalling VulkanRT version 1.0.65.1 and replacing it with the latest version (1.1.92.1); but after doing so, the vulkaninfo.exe display lacked the list of Instance Extensions (see above), so I reinstalled the 1.0.65.1 version, thinking something went wrong
- Installing VulkanSDK version 1.0.65.1
- I do not know why Vulkan is trying to locate a .json file in a directory that does not exist; I do not have a Steam folder in the Program Files (x86) directory.
- I also do not have a directory named 'VulkanSDKBuild'; instead, I have one named 'VulkanSDK'. Is this the reason why I get 'VK_ERROR_INITIALIZATION_FAILED'?
- With OpenGL (and a configuration made to increase performance), the game I was running (JJBA: Eyes of Heaven) gets a solid 30 fps in the menu, and 15-25 fps in battles (depending on the map, number of characters left, etc); I wanted to see if Vulkan fixes the the fps issue during battles.
