I am aware this is third party plugin. I have however been looking online at forums for possible solutions and noticed other people asking the same question when using unreal engine. New DLSS crash Unreal engine 5.5.0 - DLSS - NVIDIA Developer Forums
Maybe something is conflicting?
Steps to Reproduce
Unreal engine 5.3, FSR 3.1, NVIDIA DLSS frame generation plugin, Packaged build only, non editor
Our game has a graphics menu which allows easy toggle for certain graphics options:
1:Start project with all relevant graphics options disabled
2:Turn on lumen option
3:Turn on dlss option
3:Observe crash
This specific order crashes in a consistent fashion, nodes provided in attachment.
We also have random crashes occuring after some undefined time playing. Some specific computers suffer this issue while others don’t. This is however not the case with dlss/FSR disabled. Lumen does not have to enabled to crash consistently but provides an 100% repro when swapping graphics settings.
Not providing a repro project since this is a third party plugin issue but maybe this is something known?
Hi,
Thanks for reaching out about this. Based on the information you provided, the crash is most likely due to a bug inside the DLSS plugin, which we do not maintain (Nvidia owns that plugin). Can you run your game with -d3ddebug to collect more logging information? The logs can give a few more details about this particular crash.
Cheers,
Tim
