I'm having trouble with Vulkan and RPCS3.

First of all, sorry for my bad English.

I'm not famillar with RPCS3, and today is the first time I've used it. The instruction said: GPU->Renderer: Vulkan, but apparently in my renderer box there is no "Vulkan" option. As I searched for solution on Google, I found lots of people giving the following way to fix: "HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\Vulkan\Drivers", if you don't have "Drivers" key just create it and in it create a new REG_DWORD and name it "C:\Windows\System32\DriverStore\FileRepository\nv_dispi.inf_amd64_5601d21ccd639df9\nv-vk64.json", and put the value as 0."

I finished creating the required file, but then I found out that my FileRepository folder didn't have the nv-vk64.json file. So even though others successful, mine got no change. 

That's the only way I've found so far and sadly, didn't work. Do you know any other way that I can use, or, how to get the nv-vk64.json file? Thank you very much!

I cant say that im totally sure if this is your issue, but for me, i actually just fixed this 2 days ago by upgrading my drivers to the latest version. Vulkan doesnt really seem to support drivers that are too old (or if you are using an old version of rpcs3, too new).

I tried updating my drivers but unfortunately, it didn't work as well. The nk-vk64.json file is still nowhere to be found TT_TT. Is there any other way?
