RTX 3090 and AMD 5950X CPU here.
I finally seem to have fixed my random “d3d device removed” crashes by resetting my NVidia Control Panel 3D settings.
I had already increased TDR values because Substance software requires them. Still had crashes.
I gave up two months ago and was using DX11 in UE5. But, while trying to play Hogwarts Legacy this Sunday, I had way too many crashes and decided to hunt it once more. I was already on latest drivers as of April 23rd (531.68).
I like to fiddle with those NVidia 3D settings, so I thought maybe that’s how I messed up, because I hadn’t had these crashes for as long as many others. So it had to be something I changed recently, besides drivers, because I haven’t changed hardware since 2021.
I opened the NVidia Control Panel, restored defaults, and changed these settings:
After that, no more crashes in the game and Unreal has been stable in DX12. Maybe I just drastically reduced the amount of random crashes but, so far, none.
I really hope this helps someone else. I was getting sad by not being able to use the latest graphical features in the editor. These are really frustrating crashes, especially since Epic says it’s a driver bug, but only Unreal seems to be suffering from it. Weird, huh?
