DX12 Graphics Crash in Editor, Force DX11 Fixes It

themisfit · January 14, 2026, 10:53pm

I am getting constant editor crashes ranging from immediately on project open to 5 minutes after opening the project. Running with command args -force-d3d11 appears to fix the crashes. The issue first appeared in the project created in 6000.3.1f1 and after updating to the latest version 6000.3.4f1 is still constant. Project is using URP. PC GPU is 2060 Super 8gb running latest studio drivers 591.74 but this issue was still constant with driver version 581.57.

I am currently unsure how to further debug this issue. If anyone else has encountered anything similar, advice would be appreciated. Please also let me know if there is any more detail that needs to be added to this post.

Here is the crash log when running with args -force-d3d12-debug:

d3d12 validation error (catergory: 9, id: 232): ID3D12Device::RemoveDevice: Device removal has been triggered for the following reason (DXGI_ERROR_DEVICE_HUNG: The Device took an unreasonable amount of time to execute its commands, or the hardware crashed/hung.

I’d file a bug report if it is consistnent

CodeSmile · January 15, 2026, 4:06pm

Check if you have HAGS enabled, and if so, turn it off (I think you have to reboot). It can cause GPU “time outs”. I’ve had driver-level popups of timeouts recently, mostly during high-load situations (open Unity project alongside Rider and other apps). Since disabling HAGS I’ve not had these anymore

HAGS = Hardware-Accelerated GPU Scheduling
It’s in Windows settings, somewhere under Graphics.

Tautvydas-Zilys · January 15, 2026, 7:23pm

Hey, seems like the same issue as Debugging player 6.3 upgrade. Are you by any chance able to report a bug on this with a project that reproduces this issue?

Sam-person · February 1, 2026, 5:08am

We’re hitting DirectX 12 crashes consistently, on every 6.3 project, across multiple teams, and multiple computers. New Unity versions are sadly unusable if you need any DX12 features, we had to downgrade to 6.2 for now.
Filed an incident report on our test playground project, IN-132982! I hope it helps come to a solution more quickly!

All the best,
Sam

CodeSmile · February 1, 2026, 10:06am

Curious that just going back to 6.2 seems to have fixed it for you. Are you absolutely certain this is the case? In case crashes still occur, just less frequently or under different circumstances.

I and many others have zero issues with DX12 so I’m suspecting a combo of a system issue triggered by Unity (bug or otherwise). DX12 problems have been plaguing some users in various ways ever since 6.1 made DX12 the default, and they were all “fixed” by switching to DX11.

In case you have the opportunity to do a clean Windows install from scratch on a system that previously crashed I’d be curious to hear if that fixes the crashes.

Junior_Djjr · February 3, 2026, 8:23am

Me too. I just updated my project from Unity 6.2 to 6.3 (deleted Library folder before the update), and it gives “Unrecoverable D3D12 Device” when I open my main scene (not clean/basic scenes, maybe is some model or shader).

unity_27NFUoGCKItEVA · February 3, 2026, 12:20pm

I think its same problem like here: Unity Light Baking Crash On Unity 6000.3.2f1 - #19 by unity_27NFUoGCKItEVA

Tautvydas-Zilys · February 3, 2026, 10:23pm

We have a fix for this issue, it just landed to 6.5 alpha: Unity Issue Tracker - Crash on CheckDeviceStatus when moving in the scene view on a specific scene

We will be backporting the fix to Unity 6.3 and 6.4.

Paul-Swanson · February 19, 2026, 5:19am

Any thoughts on when this backport will occur? I just upgraded from 6.2 to 6.3 and have this very problem. It was perfectly fine in 6.2

Tautvydas-Zilys · February 19, 2026, 8:17am

It was released in 6000.3.9f1 yesterday. What version did you upgrade to?

Paul-Swanson · February 20, 2026, 4:05pm

3.8…naturally lol figures. missed the fix by 1 day

Paul-Swanson · February 20, 2026, 5:35pm

Should note, when i readded dx12 back then activated auto api, the editor restarted then crashed with a UNKNOWN error.
Once i removed the -force-d3d11 it loaded fine.

That looks unrelated. Does it reproduce reliably with -force-d3d11?

Paul-Swanson · February 21, 2026, 3:00am

No seems to have just been the once. shrug

aubergine · February 23, 2026, 7:59am

Just updated to 6000.3.9f1 and still crashes constantly. Not fixed.

CodeSmile · February 23, 2026, 4:50pm

For reference, for everyone, since I haven’t mentioned this here yet:

Re-install (latest stable) graphics driver with the “force firmware reset” option that the installers have a checkbox for. You may need to use the “custom” install choice to see it.

There had been two reports by now where doing that had fixed DX12 related issues. Perhaps it also helps with persistent crashes.

aubergine · February 28, 2026, 9:40am

It didnt work, though the timing between crashes extended to 4-5 minutes rather than 30seconds.

nasos_333 · June 23, 2026, 10:24pm

Hi,

I also see random crashes in Unity 6.3 in DX12, every other project i converted that worked fine just crashes, both URP and HDRP ones.

I assume under certain conditions all projects would crash, just have not activated them yet in few.

This is totally unacceptable and there is no real solution than Unity stop defaulting to DX12 as is simply not working.

Please consider removing DX12 as default, as its state currently is completely broken. And add a big warning to not use it also.

Plus DX12 is much slower than DX11, so is generally a version to avoid.

Note that i don’t see these crashes at all when change to DX11 or Vulkan in all affected projects.

Thanks

Tautvydas-Zilys · June 23, 2026, 10:27pm

Please file bug reports so we could fix those issues. The vast majority of users are not seeing crashes that you are so you must be running into some corner cases.
