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 
Only having this setting on:
There is no “proper” solution yet? Meaning by using Super Resolution its an AA method.
DLSS still is not working.
Have someone tried to use DLSS 3.7 on UE 5.5?
I tried it right before DLSS 4 came out, but if I remember correctly there was no support from Nvidias side for DLSS3.7 for 5.5. We created a custom “support” for it, but it didn’t work at all. At least DLSS 4 worked when removing the streamline plugin.
I was having the same issue in 5.6 and disabling streamline fixed it for me in 5.6. The image still seems a little less stable than I’d expect from DLAA but it is miles ahead of the ghosting I find TSR gives.
I also had the issue when packaging the level for testing. It seems the streamline core plugin was automatically included under Plugins. Deleting that file fixed the one eye issue in the packaged app too.
It’s also possible my issue was a little different as it was a dark gray color rather than pure black and it seemed like the right eye was shifted to the left eye with the content for the left eye not visible.
Hello, I also faced this issue.
The thing is, if you intend to use DLSS FG you need to activate the streamline plug-in.
What fixed the issue for me was removing TAA in the render settings.
Hi! After almost 6months, I am happy to share that the new version of DLSS that was released by Nvidia on 31 July (DLSS version 8.2) works in VR without disabling the Streamline and Framegen plugin 
Do you have all of the plugins enabled? I’m still experiencing the issue.
Thats weird. had everything enabled, even the deprecated ones.
you can try:setting→NvidiaStreamline→close Enable plugin features for the D3D12RHI
Are you using 5.5 or 5.6? Also would you be willing to share a project where dlss and vr works for you? I am using 5.6.1 and DLSS 8.2 and the right eye still renders black.
I am using 5.5
I will do a new test in a few days to see how it performs because I am starting to doubt myself when no one else got it to work.
