The previous version of the DLSS plugin for Unreal Engine 5 was working in VR but the new DLSS 4 plugin for UE 5.5 does not.

In my player controller at begin play I have the “Set DLSS/DLAA Mode (No Auto)” node set to performance mode and when I click play in VR my right eye is rendering solid black and the entire game window freezes.

I’m experiencing the same thing. Did you find a solution?

It seems like it is an issue with this release of DLSS4. You need to remove the plugin completely to resolve the black screen in the right eye issue.

The issue might not be related, as I don’t have VR stuff, but as an option, try disabling NIS. I’ve observed that it doesn’t work correctly with the latest DLSS version, and native smoothing or FSR 1 provide me with a better outcome.

I just found a solution for this

Disabling this part of the DLSS plugin “NVIDIA Streamline Core”:

Will get rid of the black eye and freezing problem :slight_smile:

Only having this setting on:

will still give better visual quality and performance in VR than not having DLSS (or FSR) at all
