Bug 2021.1 up Crashes all the time. HDRP/Dx12. Multiple monitors.

I have never experienced such instability as with trying to run Unity 2021.1.3f and up. I am using HDRP with DX12. If I attempt to move or resize any window, or sometimes just close a window, the Unity editor starts gliching and then Crashes. This is happening even with an empty project started from the HDRP template. I guess it is possible due to using multiple monitors as it seems it is more stable when the editor is only being used in 1 monitor. I filed a bug report, but I need help quickly as this is really making Unity virtually unusable.

 

Is there a reason you're using dx12? Try dx11

 

Yes, I am using raytracing, and unless I'm mistake, that is only available by using DX12. I've been using DX12 for a couple years now without having this issue. I upgraded to make use of some of the new features in 2021.3 that I really needed to use. After doing some more tests, it seems just using a single monitor still crashes Unity. I can only guess that this is some kind of bug that has to do with DX12. I am running another project with 2021.3.2f with udp and DX11 and it does not crash or glitch when moving/resizing windows. I do have a backup of the project with the earlier version of Unity that was stable, but I cannot believe the updates have such an issue, and I would very much like to continue using 2021.3.2f.

 

2021.3.2f. is a little old, try the newest one. or even 2022 as a last resort

 

I did try 2021.3.6f, but had the same problem. I will go ahead and try 2022. Couldn't hurt to try.

 

What the error you get?

 

There doesn't seem to be any error reported in the console prior to crashing.
I'm not great at understanding crash logs.
This is the editor log just prior to crash...

Crash!!!

 

try this:

Edit->Project Settings-> Editor->Cache Server->Use global settings (stored in preferences)

And

Preference->Asset Pipeline->Default Mode->Disabled

 

and check for updated video drivers

 

I tried creating a new project with Unity 2022.1.0b6, and just changed the settings to use dx12 using the HDRP wizard. Still crashing.

• Updated video drivers - Confirmed
• Changed cache server to use global settings - check
• Disabled asset pipeline - check

This error seems to always pop up when Unity is started...

d3d12: Profiler is enabled, but stable power state is not. GPU timing errors are expected.

Resized a panel... Glitching Editor, then crash...

what windows version are you on? what graphics card do you have?

 

Windows 10 Pro 21H2
Intel(R) Core(TM) i9-9900K CPU @ 3.60GHz 3.60 GHz
NVIDIA GeForce RTX 3090

 

CAn you try this

https://substance3d.adobe.com/docum...th-long-computations-tdr-crash-128745489.html

 

I gave that a try. Interesting, I had just tried the same fix a couple weeks ago prior to updating windows. When I went back in to try that fix it again my registry edits were gone. Adding them back in seemed to make no difference though.

 

try adding -force-d3d12-stablepowerstate as cl flag

I think it would be like this:

"C:\Program Files\Unity\Hub\Editor\<version>\Editor\Unity.exe" -force-d3d12-stablepowerstate -projectPath "<project path>"

https://docs.unity3d.com/Manual/EditorCommandLineArguments.html

 

>>try adding -force-d3d12-stablepowerstate as cl flag
I gave that a try. It did resolve the stable power state error, and it also seemed to make Unity start up really fast, but it did not fix the crashes. I even tried Unity 2022.2.0a18 where dx12 is out of experimental, and it also crashes after resizing or moving windows. I have tried running other dx12 applications and they seem to run perfectly well. I tried installing several different drivers from NVidia, but this did not seem to help either.

 

I'm out of ideas sorry what's your desktop resolution?

 

No problem. Thanks for the ideas though. My res is 1920x1080. I tried unhooking my other monitors and tested with just one, but the same crashes occurred. If I come up with any solution I'll post.
It's probably just some dx12 setting somewhere that isn't configured correctly for some strange reason.

 

Update! Never trust NVidia updates!
I uninstalled my NVidia drivers and installed drivers from 2021. FIXED!!!!
Fixed on all unity version!

 

Glad to hear! Keep in mind the things you have changed here, like the command line flags. I'm not sure if they will have unintended consequences in the future.
