Constant Crashes - Failed to present D3D11 swapchain due to device removed.

Unity Engine

If only some Unity support representative showed up in this thread… it’s obvious there’s an issue that isn’t our fault.

i just got a 3060 ti and updated my drivers, and suddenly i cant even load unity, even on a blank project! Am using 2020.1.15f1

Any update on this? About to swap my 2070S for a 3080. That would not be good at all.

I have the issue as well in 2020.1.16. TdrDelay and firewall exceptions doesn’t work here either!

25

If this might help someone; Had the same issue, constant crashes in Unity 2020.2.1f1, with silly small scenes in a fresh install. Managed to fix it (toi toi) by uninstalling the Nvidia Geforce Experience that came with my 3070. No crashes since.

26

I just deleted the library, fixed the problem for me

The library folder in the project?

28

Yes.
It’s a go-to fix. So very often (especially after upgrade) it fixes stuff like: Missing Monobehaviour, Messed up UI etc.

please I need help

HI guys,
I was getting this same message. Actually, even prior to getting that message, my unity would crash and I would have to restart UNity. FOUND THE SOLUTION TO BOTH ISSUES:
I have an NVIDIA GETFORCE GTX 960…so I uploaded the most current drivers from nvidias driver site and now everything works - no more f’king crashes ! So, i have to thank some of you guys who had made the suggestion of updating to the most current graphic drivers.

Had this problem with 2020.2.7f1 release (was not happening with the 2019 LTS version)
I was using NVidia 460.89 drivers with the 2020.1, updated to current 461.72 (as of this day) and it seemed to stop
(NVidia GTX 1660 Ti, intel i5-4570S)

32

Hey has anyone figured this out for sure? I am having this issue now as well…

33

I’ve tried making a whole new project in New LTS 2020 and 2019 and am still having this same crash with nothing even in my project.

34

And I’ve also tried ever solution currently listed on this page.

35

its mid march and this is still happening. I cant continue with this. I was really close to replacing my Graphics card, as everything else works… but I cant afford that. Ive started to consider that Unreal is a more stable product and platform to developer for clients, with slower releases, but they are tested. Im tired of us being the test bed for new Versions. 2019 worked really well, now… well it doesnt.

the catch here is any GPU hang/crash would end up with the same error message in unity, as well as any driver issues would end up there too. unfortunately we dont have ability to catch the gpu hang/crash before present.

Sometimes having a very complex mesh / compute shader etc may trigger windows GPU hang detection. Deleting library (especially if upgraded the unity versions) is another way to remove the corrupted mesh/shader data. and Updating to the latest drivers as the underlying issue may have been fixed.

I could not find a bug filed with this problem. if you have a project or a repro case and file a bug for it, we will investigate it.
thanks

Had the same issue for quite a while and was able to resolve it by deactivating the SVT mode in my UEFI. At first I had the Nvidia driver in mind as a culprit, but doing all the things mentioned here in the thread did not resolve the issue.
For about 7 days now, I never had that issue again after disabling cpu svt (virtualisation). (Ryzen5 5600, Gigabyte B550)

Maybe it helps others.

This issue has only started to pop up with Unity 2020, so it is clearly due to something Unity changed, not GPU drivers or submitting excessive workloads to the GPU. I even have it occur during shader compilation at times.

Unity seem to be putting all the blame on the user/OS/GPU/Drivers, when it’s clearly only an issue that has started to pop up after upgrading -Unity-.

I’ve had this occur with very simple compute shader workloads that complete in under 1ms, there’s no way they could possibly be triggering the TDR. (They also only started becoming an issue when I upgraded)

Examples of the problem only appearing since Unity 2020:

Because Unity does 3 parallel releases without testing even the extreme basics of any of them

This is really getting out of hand, why cant they focus on making just one version that works
