Switch to DX11 in UEFN? to resolve-> Fatal Error: DXGI_Error_Device_Removed Crashes

[mattacreates]

My UEFN project keeps crashing, throwing the error in the attached file.
UEFN Error.txt (329 Bytes)

A few people have experienced it in UE5, and it seems the solution is to run DX11 instead of DX12. It’s not an ideal solution, but I just want to make my game.

UE5 crashes on windows 11

Fatal error: with error DXGI_ERROR_DEVIC I have seen this error over dozen times. I heard that the reason of this crash is windows 11 or gpu(I’m using 3080ti). Here are my two questions. Am I really need to downgrade my OS? and need to underclock my gpu?(I didn’t overclocked, turned off MSAA, and installed latest driver) Who is the villian on this mass? Epic? Nvidia? MS? Surprisingly, this major problem doesn’t fixed over a year. I guess only few people going through this problem. ha.

Does anyone know how to switch UEFN specifically to DX11 (not Fortnite)?

Thanks!!

Sorry for the late response. I did not find a good solution except being on a really old driver version for my 2080 super. This was a while ago so I don’t recall which one it was but at this point the driver’s likely a year or more old. I believe this issue also caused Fortnite to crash regularly. Since I was ready for a new gpu and was frustrated, I jumped to an AMD GPU to go with my AMD CPU and I haven’t had any issues since. I also have an NVIDIA 3060 mobile with no issues so not sure what was going on but a tried a lot for days. GOOD LUCK!
