Vulkan Renderer missing on NVIDIA driver version 390.65 [Fix found]

Hi I just currently downloaded the Rpcs3 emulator. I cant seem to find the Vulkan option no matter what I try. I have downloaded the drivers and everything and still nothing.

Hi,

I have downloaded the new Version and saw that Vulkan as Option is missing.

What happened?

Greetings

I just downloaded the latest version and I have it, so chance are, you need to apply this "fix":

If you have Intel, follow my instructions, if you Nvidia, follow Ani's instructions.

If by some chance you have AMD, then you need to apply the same procedure, but you need to find the folder where the json file for AMD is stored.

This is exactly worked for me. Thanks.

GeForce 390.65 installed, followed Ani's instructions with Regedit and also the vulkaninfo.exe.
Doesn't work, while Dolphin still offers Vulkan.
Any idea???

Did you follow Ani's steps to the letter, or did you use your own path?

If you followed Ani's, then it could be the path to the file is wrong.
When you run vulkaninfo.exe, does it says "loaderGetDeviceRegistryEntry: Located json file..." at one of the lines at the start?

Thanks for your advice! Yes i used the letter version.
Now I found that i have 2 versions of Vulkan.
One is 1.0.3.0 with the first 29 lines of vulkaninfo:

I'll try to understand what you mean and will search on.
But i'm always full of thanks for other ideas.

(Sorry for my post, its my first membership  in a forum and english is my second foreign language) :-(

@"albundy" Ah, I see, I will try to keep it simple then.

So here are the steps you need to follow:

1. Check what is the latest version of Vulkan you have
- Path should be at "C:\Program Files (x86)\VulkanRT\", open the folder with the latest date (that is, highest version number) and run vulkaninfo.exe
- I assume this is the 10.0.65.0 from above, so that's done.

2. Go to "C:\Windows\System32\DriverStore\FileRepository\" and look for folders starting with "nv_dispi.inf_amd64_"
- Open the folder with the latest date (should be the date when you installed the drivers, but just pick the latest one)
- Find the "nv-vk64.json" file and copy the path to it
- Path will look like this: C:\Windows\System32\DriverStore\FileRepository\nv_dispi.inf_amd64_xxxxxxxx\nv-vk64.json, where xxxxxxxx is the random text in the folder name

3. In registery editor (regedit), go to "HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\Vulkan\Drivers"
- Right click on the "Drivers" folder and select "New > DWORD (32 bit) Value" and paste the path to nv-vk64.json you got earlier (make sure there are no quotes) as the name
- The value should be 0 by default, but if not, double click the new entry and set value to 0

4. Run the vulkaninfo.exe from the latest version again
- it should say that it loaded the json file from registry, even if not, try looking if RPCS3 can load it


If this doesn't help, then somebody else needs to help.

Thank you very much. Searching for the json-File and changing the registry works.
Vulkan is running again!!!
