GPU Crash 4.26 and .27 with Raytracing settings enabled

Hi Everyone,

In Unreal 4.26 and 4.27 unreal keeps on crashing after around 5 to 10 minutes and I receive the error d3d device removed. In the error screen after the crash it is related to RT12.
I came across more people with the same issue’s and the recommend a few options:

  1. Using Nvidia studio drivers - Check
  2. Reinstalling nvidia drivers - Check
  3. Reinstalling UE4 - Check
  4. Changing the TDR delay to 10 seconds - Check
  5. Not using programs like MSI afterburner - Check
    Even with these options done I keep running into the same problem.
    The strange thing is I don’t have any issues with UE5 what so ever.

Anymore tips on tackling this problem? Thnx in advance!


have you received the answer you need? If you have, please share because this is also the problem I want to solve


Not yet unfortunately. Will keep you posted, if I here something.


What’s your GPU?


Asus TUF 3090


In that case it shouldn’t be crashing, is it a default scene? If not is there any features that you’ve used or anything else that might impact the graphics that might not be properly supported with ray tracing?

A new studio driver got released today and that seems to have fixed the problem for both version .26 and .27 :slight_smile: Have been using both for some time and both seem to be stable again. The crashes where random in both versions.

@shayleelindgren see if this works for you.

Which version number driver do you have? I’m running into the same issues.


I’m using studio driver version: 471.41


I also had the same problem using an RTX 2080 card.
