SU14 and Reprojection Mode: What's really going on?

So from the last mention of DLSS FG, if we were willing to accept an increase of one frame (11msec for 90Hz) latency, could we have better motion reprojection image quality?

No it’s way more than that unfortunately.

I wrote an analysis here, it’s 4 times this number.

Will DLSS 3.0 be supported in VR msfs?

Here is my current take, I’m trying to reason on how the DLSS 3.0 frame rate upscaling could work in VR, and what kind of latency you would be getting and why this would be very challenging to “make it right”. DISCLAIMER: I have no insider knowledge of DLSS 3.0, there is no technical documentation available AFAIK, except for the FRUC article I posted above. Nothing I’m writing here is backed by technical data from Nvidia. Everything I write down here is based on a quick analysis after drawing …

Regardless of latency, what’s truly the blocker for DLSS Frame Generation in VR is the poor performance of the interpolation, which I described here:

OpenXR Toolkit (upscaling, world scale, hand tracking...) - Release thread

It’s been a while since I’ve shared some updates on random topics. So I’ll share one now. Back in October last year, I started thinking about DLSS Frame Generation (or DLSS FG, please call it that and not DLSS 3 - because that’s confusing!) and how to use it in VR. I wrote a post here explaining potential challenges with latency. Back then, Nvidia had not released any developer interface for DLSS FG, so there wasn’t much to do. I never take “but it shouldn’t work” for granted, so I had always …
