Ensure condition failed: VendorId != EGpuVendorId::Unknown

Hi, I’m running UE 4.25 on Debian Testing with Nvidia GTX 1060 drivers v460.32.03.
I have the following error on boot:

The Editor starts up anyway and I am able to work but the performance seems quite poor (I know it’s an old GPU but it’s hard to buy an RTX today).
I would like to try to solve the problem hoping for an increase in performance, does anyone have any idea how I can get rid of this error?

Thank you

Acheta_Games · February 3, 2021, 12:56pm

Strange, that issue does happen with an out of date drivers, but yours are up to date. Are you sure you are using them and that you are using the proper GPU? That is not an old GPU for the Engine to have a poor performance because of that.

joaulo · February 3, 2021, 4:08pm

Thank you for your support, yes I’m using them and just updated to latest 460.39 but sill get same error.

Shadowriver · February 4, 2021, 1:17am

Looking on source code, on vkGetPhysicalDeviceProperties, gives vendorID that UE4 can’t identify and it seems expect PCI’s vendor id as EGpuVendorId seems to use it

enum class EGpuVendorId
{
	Unknown		= -1,
	NotQueried	= 0,

	Amd			= 0x1002,
	ImgTec		= 0x1010,
	Nvidia		= 0x10DE, 
	Arm			= 0x13B5, 
	Qualcomm	= 0x5143,
	Intel		= 0x8086,
};

check lspci command if it’s match, also check if other applications work, check some diagnostic tools if you can to see what vendorID property gives to UE4

By looks of it straight considering you got nvidia there something wrong with drivers, more specifically support of it

That said… i’m not kind of fan that UE4 locks it self to specific vendors and intentionally crashes it self it not on this enum list. Generally if GPU is compatible with it should just work no matter the vendor

SaladinAyyub · February 4, 2021, 2:44am

This is also on AMD

Engine version - 4.26.1 with latest patches till now.

joaulo · February 4, 2021, 9:26am

Thank you for your support, in fact I hadn’t thought of a driver / system level problem I had just focused on the UE side because all other apps works well.
I use latest Blender and Krita but don’t know if they use API or still OpenGL.
This is output from lspci:

Hi,

It looks like you’re running on the software renderer (llvmpipe) instead of your GPU. GTX 1060 is perfectly enough to run the editor with full performance. The llvmpipe vendor id is not known to the engine, hence the soft error, which is actually hinting you that something is very wrong…

As per why llvmpipe ends up getting used instead of NVidia drivers - unfortunately I don’t know. Likely a problem caused by optimus?

Regards,
RCL

joaulo · February 5, 2021, 11:32am

Thanks for the support, it’s a big step forward, I’ll keep trying to understand why it’s using the software renderer instead of the hardware.
I am sure that other programs are using accelerated hardware, i.e. Blender recognizes and uses CUDA with the 1060, so I don’t know where the problem lies, as it only occurs with UE at the moment.
I don’t think it’s an Optimus related problem because I’m on a desktop PC, no integrated GPU, only the video card on PCIex so I don’t have Optimus / Prime / Bumblebee or any other GPU management software installed, just Nvidia + Cuda drivers.

Sorry for late reply I have not seen your question and have not received a notification
Unfortunately I have not found a solution yet and now I have another big problem, I have changed my PC and now cannot build UE4 anymore

later-do-it · July 26, 2023, 1:11pm

same problem when run UE4.26 on unbuntu20.04., but UE5.2.1 is ok.

RebeccaC0101 · October 9, 2023, 1:10pm

I used an RTX 4060 graphics card to install Unreal Engine 4.25 and Airsim and had the same problem.

I tried to reinstall the driver and CUDA, still no solution.

Have you solved this problem?

anonymous_user_d1150ec41 · December 7, 2023, 5:57pm

Hello there,
I had a similar issue by launching UE4.27 from a docker container. I was able to solve it by changing the nvidia-driver to 535.129.03-0ubuntu0.22.04.1 in POP_OS 22.04.
