When I double click on the program I get the following error showing that I don't have the drivers I have checked everything and it is correct I have even installed it again and it is still the same.

Steps to reproduce

Open ./Godot_v4.0-alpha1_win64_console.cmd or ./Godot_v4.0-alpha1_win64.exe

Minimal reproduction project

No response

I don't think there's anything we can do about this. Setting DISABLE_LAYER_AMD_SWITCHABLE_GRAPHICS_1 to 1 automatically is probably not a good idea, as it will prevent forcing the use of AMD integrated graphics entirely when a dedicated GPU is present. For non-game applications, this can be problematic if you want to preserve battery life.

Did you update your graphics drivers from AMD and NVIDIA's websites (not from your laptop OEM or Windows Update)?

I have updated all the drivers both from windows update first and then from the manufacturers page with their latest versions.

If I understand correctly, with DISABLE_LAYER_AMD_SWITCHABLE_GRAPHICS_1 both devices should be accessible, without it, it's presented as a single device.

@fonixgm Could you try running Godot with --verbose command line argument (both with and without DISABLE_LAYER_AMD_SWITCHABLE_GRAPHICS_1 set), and give us the output ("Vulkan devices:" part in particular).

This is with DISABLE_LAYER_AMD_SWITCHCHABLE_GRAPHICS_1 on

and this is without the DISABLE_LAYER_AMD_SWITCHCHABLE_GRAPHICS_1

[bruvzg]

I have not found much useful info how VK_LAYER_AMD_SWITCHCHABLE_GRAPHICS should work, but it seems broken (there are also plenty of similar issues with the layer on Linux, so it's not Windows specific).

With the layer disabled, it should be possible to force a specific GPU for the app using Windows built-in option in "System→Display→Graphics". But I agree that we probably can't do anything with it.

Temporarily I will use the DISABLE_LAYER_AMD_SWITCHABLE_GRAPHICS_1 to make it work and I will also investigate if there is any configuration that can solve this problem apart from using this environment variable and thus not to annoy so much the battery of my pc.

I reproduced this with a similar combination of graphics cards and fixed it locally by adding "OS::get_singleton()->set_environment("DISABLE_LAYER_AMD_SWITCHABLE_GRAPHICS_1", "1");" to the function Main::setup in main.cpp, immediately after "OS::get_singleton()->initialize();". At least the Windows implementation for that function changes the environment variable only for the current process (at least according to the documentation). Is there any reason not to do this? Updating my graphics drivers didn't do the trick and I guess it might take some time till most users with such a (not that unusual) graphics cards combination will receive an update that fixes this issue.

[Mikadini]

i want to comunicate i solve a similar problem ( #56164 ) i simply remove the official asus amd driver and put the generale amd driver using the adrenalin software this solve the problem for me.

How will this behave on systems with only AMD integrated graphics? Can anyone test this on such a system?

[akien-mga]

Please try 4.0 alpha 10, there was an update to VMA which might help: https://godotengine.org/article/dev-snapshot-godot-4-0-alpha-10

(Reading again, maybe not - but there's no harm in testing :))

[fonixgm]

I have tried alpha 10 but the error persists.

[Ramedes]

The Error occurs on Branch 3.x, 3.4.x and 4.x

On my System i have a integrated Radeon AMD Vegas 11 Graphics card and a additional, second NVidia Graphics card.
I simply turned the AMD Vergas Graphic card up in Windows 10 Device manager (Nvidia still was enabled), the Editor
launched without any problems. After it, i was able to re-enable the AMD Graphics card in Device Manager (without Reboot)
and the Editor starts without any Problems.

[Calinou]

Godot 3.x uses an OpenGL renderer, so Vulkan-specific issues like this one don't affect it. If you encounter this on Godot 3.x, it's due to something different which should be tracked in a separate issue.

[Ramedes]

I built 3.x, 3.4 and 4.x and the error shows up on any build, with tools or without, if it is release or debug targets or both.

I don't know. I don't have such a system.

If any of you can still reproduce the issue, please test #73450 locally. A Windows build is included in that PR's description.

[MonT97]

Update AMD Radeon diver can solve this problem

confirmed here :
R7 4800H
GTX 1650

got the driver from AMD website

Thank you, its'working!!!

[yarre-uk]

Bumping because I had this issue too. An easy, temporary solution on Windows to force Godot to use the NVIDIA GPU is editing the cmd script to locally set the DISABLE_LAYER_AMD_SWITCHABLE_GRAPHICS_1 environment variable only for the given session.

@echo off
setlocal
	set DISABLE_LAYER_AMD_SWITCHABLE_GRAPHICS_1=1
	Godot_v4.0-beta1_win64.exe
	pause > nul
endlocal

hello, tried your fix, and godot closes without any errors, just "not responding"

Works for me!

[TATAPNHOB]

My errors are like these. It seems that it recognizes the dedicated GPU, but still cannot initialize Vulkan. Actions from the aforementioned video do not work, as it seems.

Try 4.1.rc2 as it includes #73450.

Are you using external monitors by any chance?

[TATAPNHOB]

4.1.rc2 works! Thank you. I don't have any external monitors though.

for those of you arriving here in 2024 after January 27th, the issue is detailed here:
https://community.khronos.org/t/cannot-create-vulkan-instance-non-conformant-vulkan-implementation/110488/3

I’m having the same problem. Yesterday, I could open Vulkan-supported applications, but now I can’t. I updated the driver, used DDU to uninstall and reinstall it, but nothing changed. Example Vulkan applications also don’t open. I downloaded “VulkanRT-1.3.275.0-Components” from the LunarG website. The x86 version works with a warning that “dzn is not a conformant Vulkan implementation, testing use only.” However, the x64 version only gives a warning. Sometimes GPU-Z shows that it supports Vulkan, but then it disappears when the application is refreshed. My system: R5 5600G Vega 7(Cezzane), OS: Windows 11.

Edit: Uninstalling the “OpenCL™, OpenGL® and Vulkan® Compatibility Pack” fixed the problem.

This solution worked for me. You can easily find and uninstall this in "Apps > Installed Apps" in Windows settings. Click the 3 dots, uninstall it, and it should start working again.

bro... this is not fixed yet?

bro... this is not fixed yet?

I've stopped running into this issue some time ago using godot 4. Though I'm not sure exactly which version fixed for me I'm currently on 4.2.1

[akien-mga]

This was fixed in 4.1. If you still experience a similar issue in 4.2.1 or later, please open a new issue with details.

[nathan130200]

I'm in latest 4.2 and still happen this issue. I must add --rendering-driver opengl3 param to bypass this. Godot don't check for which render devices they can use, just enforce vulkan by default.

The same error is displayed
