Viewport crashes when UnrealEngine 5.1 DLSS is enabled

I am using Unreal Engine 5.1. All drivers and Windows are up to date. If the “Enable DLSS/DLAA to open in Editor viewports” option is True, the UE Crashes when I make the Master Display Window full screen. But if I don’t make it full screen, I use it with windows and I don’t make the window too big, it doesn’t crash, I can use it. If the “Enable DLSS/DLAA to open in Editor viewports” option is False, I can use it without any problems, but this time it is not active during dlss editing. My graphics card is RTX 3080Ti.

Welcome back @tunayeniyayla to the NVIDIA developer forums!

This is the first time I hear of this kind of problem. I’ll see if we can reproduce and check if this is a plugin issue.

Thanks for bringing this up!

Let me make one more add-on. While writing the subject, I said master display windows, but this would be wrong. Open a blueprint and make that blueprint’s Viewport full screen. Unreal Engine crashes if DLSS is enabled. It doesn’t crash if DLSS is not active.
