Failed to Enumerate Physical Devices (Vulkan error)

[Asparagusman]

Specs:
Processor AMD Ryzen 7 5800H with Radeon Graphics 3.20 GHz
Installed RAM 32.0 GB (31.4 GB usable)
System type 64-bit operating system, x64-based processor
GPU: RTX 3060Ti (Notebook) version 536.67

Problem:

When selecting "vulkan" and then selecting "play"

The error in title immediately pops up and the game crashes.

Would appreciate all the help.

Bump. Same problem here - Vulkan works on my 3060 desktop, but not my 2060 laptop.

I not even tried vulkan. vulkan not work for me anymore too on rdr2
It runs fine for me on directx

I have exactly the same problem. Game works fine on DirectX but on Vulcan I have: "failed to enumerate physical devices". I have laptop Acer Nitro 5 with RTX 3060

Bump
Same problem on laptop

+1 on this issue, also on laptop

From what I can see unless you have a 4000 series RTX gpu on laptop you can't use vulkan with a laptop gpu, Not a single laptop gpu is supported by the software.

Links to the Nvidia specific page and the vulkan page to check and see if your hardware is compatible.

I have a laptop 3070 so I feel your pain...

Same issue, same machine

NsKush, unfortunately that's incorrectly. Update your AMD drivers. I had the same issue on my Legion 5P (4800H + RTX 2060). Annoyingly, the drivers don't show up for updating in either Windows Update or Lenovo Vantage, so you have to download the package directly from AMD.

Anyway, drivers were updated, and the game runs fine with vulkan now. The first launch might sit on a white screen for a while but just wait it out. After that it launches just like dx11.

Hi all,
I have found the solution. it's not ideal but it works. All you have to do is disable built-in graphic card, so the only one will be your Nvidia card. Then game works just fin on Vulcan but first run as sktfm wrote might take some time with white screen.

Could you link the driver page? I have the same laptop as you, can't seem to find any driver related to vulkan.

found it. https://www.amd.com/en/support/apu/amd-ryzen-processors/amd-ryzen-5-mobile-processors-radeon-graphics/amd-ryzen-5-4600h

This is completely false NsKush has no idea what he's talking about.

Vulkan works on 1000 series cards including laptop GPU's. This includes the GTX 1650 but if you have an AMD processor instead of Intel you may encounter launch errors. To remediate this please update Environmental Variable found in Advanced System Settings within Windows.

Thank you so much, you're the only person who helped me

I've another workaround similar to what @duch has suggested.

For me, I could disable Vulkan to look for AMD integrated GPU setting environment variable preferably with the following PowerShell command:

[Environment]::SetEnvironmentVariable("DISABLE_LAYER_AMD_SWITCHABLE_GRAPHICS_1", "1", "User")
