DLSS resolution in VR

For those that might be interested, I think these might be the values of DLSS resolution / super sample required to get back to the original image. In all the scenarios, my FPS was stable at 30. Multiple values were tested, and it appears that setting SS as the square root of the scale factor given from this table NVIDIA DLSS Resolutions works pretty good. I’m not saying these are the official values, just that I find that it works and thought I would share it.

DLSS Setting Input Resolution Scale Factor VR SS
OFF 1.00 1.00x 1.00
QUALITY 0.66 1.50x 1.22 (√1.50)
BALANCED 0.58 1.72x 1.31 (√1.72)
PERFORMANCE 0.50 2.00x 1.41 (√2.00)
ULTRA PERFORMANCE 0.33 3.00x 1.73 (√3.00)

VR SS refers to which setting in the sim?

When I use DLSS Quality, I set the OpenXR rendering to 120%. For me this gives a comprable visual comparison while still getting some performance benefit. I’m also using OpenXR Reprojection as well.

It’s not a setting in the sim, it’s the super sampling of the VR headset. You set it through the Oculus Debug Tool, through OpenXR Tools For WMR, through Steam etc. (Depending on the headset)
