Hi @albertotrunk.ac, welcome to the NVIDIA developer forums.

Thank you for that link. Very helpful and sane advice in the first video on that post. I would also suggest to @sce48 to first do the typical triaging of the error. You should also look more closely at the log output of UE before the crash. Chances are there will be warnings or errors already present, telling you more details.

The second video in the linked post on the UE forums should be considered more carefully. This kind of under-volting is not officially supported and if it causes a defect in the GPU you might lose warranty.

Disclaimer aside it is a very common practice to ease overall system and GPU load in terms of power spikes and might help avoid crashes.

what? it’s happening to all Unreal Engine users

I don’t understand what you mean. I don’t think that every UE user MUST undervolt their GPU to have it run normally.

6

no one is doing that, I think is clear, i have no idea why you think so

Ok, I try to clarify. On Feb 6 you posted the first time and linked to a UE forum post from Nov 22. That UE post has two videos. The second video is this: [Fix] GPU Crashed or D3D Device Removed Error in Unreal Engine (Nvidia 30 series) - YouTube which talks about using MSI Afterburner to undervolt your GPU.

I was referring to that video with my remark.

And thanks for your additional link!

Apologies I did explain very bad, my point was: to reinstall drivers as clean installation

But I mean, that crash is happening to all users (including myself) after ue 5.1 update

🙏 thanks
