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.
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 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.
