UE5 crash consistantly due to GPU crash

[Piash]

I tried to solve it by following all the possible solutions on the internet

1. Tried to setup windows and install UE5 - Not working
2. Updated Nvidia studio driver - Not working
3. Tried registry editor TdrDelay and TdrDdiDelay changing the value- Not working
4. Tried deleting afterburner - Not working
5. Tried downgrading the Nvidia driver- Not working
6. Tried fixed framerate and screen percentage on the editor- Not working
7. Tried deleting Intermediate and Saved folder - Not working

Is there anything I left to try?

Is there any more thing to try? I worked on several projects a few weeks ago. But after that, it is consistently crashing.

With Default and DirectX 11 it is working fine. But I want to use Directx 12, Ray Tracing, Lumen, Nanite, GPU Lightmass all these features.

PC Specs:
i9 12900k
64 GB Ram
RTX 3090
Asus Proart 4k Monitor

@Piash you could try my solution. I had the same issue and tried everything you did.
I ended up altering some source code and haven’t had a crash since.

UE5 gpu crashed or d3d device removed

@Joshuab_artist I had the same issue. I updated to Windows 11 and then UE5 kept crashing my 3090. I tried everything I could find in the forum. Edits to registry, uninstall afterburner, added UnrealEditer.exe to RivaTuner, switched to studio version of Nvidia’s drivers, changes to Nvidia Control Panel, and updated Nvidia’s latest driver that mentioned performance fixes for the UE5 editor. Nothing worked, so I edited the c++ files that @TarlRaney mentioned in the third post in this thread. I had…

If you use the launcher, here is the compile .dll file…

UE5 gpu crashed or d3d device removed

@Joshuab_artist I have several programs open when using the editor and no problems. But I have an AMD 5950k and 64gb of ram, so if you are using a lower end machine, it is possible to have too many programs open at once. I believe the D3D HUNG error has to do with Windows 11 and Nvidia drivers not playing nice with each other on some video cards. When the Unreal Editor or some Unreal games are in this environment, the card can crash. If you want to give the compiled/built file a try, here is t…

there was a windows update so gfx drivers need to be reinstalled
you could try the game ready drivers
when you reinstall, select clean not express

[Piash]

I will give it a try. Will confirm if it works
thanks for the reply

[Piash]

Let me find if there is any gfx driver update
Will give the update
thanks

Hi, I checked replacing the .dll fix.
It is not crashing with lumen only
Whenever I enable ray tracing, gpu lightmass then the gpu crushes again.

Thanks, that helped, but it says it can’t run Nanite. Now my foliage is not visible in distance and Max Culling Distance doesn’t change anything. Is it possible to return Nanite back?

What version of UE are you using?
I used that fix for UE 5.0.3 and haven’t used it since 5.1 (my guess is they may have changed the base code for Dx12 since then).

I haven’t had the GPU crash issue for a while and I’m using 5.3.2 and testing 5.4 Preview 1.
I’m using a RTX 3090 and Win11.

The message window says your system doesn’t support Dx12 which is needed for Nanite.
If you’re using a Dx12 PC, I’m not sure why your getting that error

Note: I set the GPU power limit to 80% in Afterburner a while back to cut down on heat.
Not sure if this was preventing the crash. I turned Afterburner off and tested in 5.4 and wasn’t getting the crash, but it could just be I didn’t let it run long enough for the crash. It only used to happen when I was running PIE and would crash within 5 minutes or less.

Hey, I’m on 5.3.2 and also have RTX 3090 but WIn 10.
I removed this D3D12RHI.dll because it seems like it disables SM6 shader and I can’t use Nanite.

The crash seems to be fixed forever after I underclocked my 3090 in Afterburner way down to 1600Mhz. Now I can load the viewport with massive scenes with Lumen+Nanite+Hardware Raytracing and everthing is fine!

Can’t tell you how happy I am, I have this deadline project going on and couldn’t work 5 mins without this error, spent a week trying to fix it and no other solution helped (I tried them all believe me)

Cool, glad it’s working for you. That GPU crash has been a plague for many since UE5 came out.
