How do you make upscaling work in VR?

I’ve been having trouble trying to get any form of upscaling to work in VR on Unreal version 5.2.0 using OpenXR.

DLSS: DLAA works but setting screen percentage causes it to crash.

FSR and TSR: Setting the screen percentage shrinks the viewport for distance meshes? At least that is kind of what it looks like.

Example:
This is in the left eye. You can see the line divider where the right side should start on the right side of the image. The close terrain renders mostly normally, but the distant landscape only renders in the shrunken viewport. The right eye is missing most of the image since it has shifted partially to the left eye.

Here you can also see the faded outline of the hidden area mesh if you look at the sky. Very strange.

Does anyone happen to have encountered this before or know of a way to fix it?

Thanks for any help.

I am having the same exact issue, a workaround is to use the deprecated SteamVR plugin to run instead of OpenXR. But I am looking for making OpenXR work with this.

I have found that it’s directly tied to setting r.ScreenPercentage that causes this visual bug, but without it DLSS doesn’t apply. And vr.PixelDensity doesn’t make DLSS apply either.
