I’m using 4.26.1 with Raytracing and Direct X 12 turned on. I seem to be getting almost random gpu crashes when doing things like exiting game mode, moving simple cubes or even just scrolling through the content browser. The error i am receiving says:
GPU Crashed or D3D Device Removed.
Use -d3ddebug to enable the d3d debug device. Check log for GPU state information.
Im not sure whats going on the pc is brand new with a gigabyte 3090, ryzen 3600, 32gb ram. and 850 watt power supply.
When looking at the crash file, i am finding this text at the end:

Same, I submitted a ticket but no one answered yet! it s a shame because I bought a power machine to use Unreal with Raytracing. Its a AMD Ryzen 9 3900X with MSI RTX3090 32GB Ram and I can use Unreal only with Raytracing turned off!
The drivers r updated but as you guys I only to play a bit, moving a simple cube or playing with the starter kit materials to get the same crash msg.
I had trouble every 15 minutes all weekend, non-stop bug reports and crashes. Then I realized: The crashes happened after installing NVidia’s driver 471.11-desktop-win10-64bit, but Unreal was stable with the driver supplied by Microsoft and Windows 10, which is versioned 9/30/2020 27.21.14.5671. This is stable so far.
Also, to get a crash, I don’t have to do all that much. Sometimes the crash triggers just by clicking on File or Edit menu then running the mouse back and forth along the menu bar, which probably accesses the Windows SDK and DirectX render calls, it will crash out. The crash always takes time to occur, like 10 to 15 minutes.
With the 471.11 driver and crashes, I also tested disabling the TDR (Testing and debugging TDR during driver development - Windows drivers | Microsoft Learn) by setting TDRLevel to 0. (This is a development/test level setting and not good for production run-time use.) What happens then is Unreal no longer crashes, but you see repeated “black screen” resets to the graphics card. Keep in mind the card and system are never under load when these resets are occurring.
My system is ASUS RAMPAGE V, Intel Core i7-6950X @3.00GHz 10 Cores/20 Logical processors, 64GB DDR4 3200 RAM, HAL is 10.0.19041.1081 Microsoft Windows Pro 10.0.19043 x64.
GPU is NVidia (Reference) 2080 Ti with 12GB VRAM. I also have an ASUS 2080Ti brand new that I can try to see if there’s a difference between the two manufacturers but same architecture.
