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

Ani

Now, we can and have already found a solution for this. We updated RPCS3 to build with newer Vulkan versions, which have an additional different method for detecting whether it is present or not, so Vulkan will now appear without ICD key being registered.

And broke support for old drivers? 388.71 & vulkan 1.0.61 give me:

Code:

F {rsx::thread} class std::runtime_error thrown: Assertion Failed! Vulkan API call failed with unrecoverable error: Device lost (Driver crashed with unspecified error or stopped responding and recovered) (VK_ERROR_DEVICE_LOST)
(in file c:\projects\rpcs3\rpcs3\emu\rsx\vk\VKHelpers.h:1162)

Known issue with latest NVIDIA drivers.

Under "HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\Vulkan\Drivers", create a new REG_DWORD, name it "C:\Windows\System32\DriverStore\FileRepository\nv_dispi.inf_amd64_5601d21ccd639df9\nv-vk64.json", and put the value as 0.

Hi I just followed the steps and still can get the vulkan renderer option , this is what vulkaninfo . exe  shows for me after I made the steps you mentioned, I have a ryzen 3 2200g and a gtx1050ti:

Thanks in advance

You're not supposed to edit register any more, use DDU and fully reinstall the drivers

Just did it ,used DDU , made a fresh new driver installation, didn´t work , when I had just the ryzen 3 2200g  vulkan was  listed , now with the gtx 1050ti , that option has just vanished

You fully removed all traces of the previous AMD drivers? With DDU that is
Your vulkaninfo shows an AMD entry, it looks like driver conflict between amd and nvidia.

The Vulkan information I posted before  was  actually before I did the DDU fresh driver installation, now that I did that  , I dont even have a Vulkan RT folder in Program Files (x86)

By the way , I dont even have the Vulkan SDK listed in my installed programs anymore  (looks like DDU just wiped out this one)

I wrote a python script to fix this issue for those who need it. Just run it whenever it breaks and it'll automate the process in the original post.
