That happens because Grass is animated in many games by a Trick colour vertex colour Animation. That cannot be represented in RT since it is not actually moving the geometry.
Ray tracing is World space, not a screen space post process...
Haha no. DF forever Baby.Were you just offered a job by Nvidia?
Anyway, great video.
Do you really think that training cost is that high? I thought that quad 2080ti setup running for few days should be enough to train it.
Btw i know that it needs tensor cores, but i was not talking about 3rd party, but Nvidia tool, so devs can implement it themselves. In the end it benefits nvidia, as more people will be eager to buy their hardware if the support is there and its good. Its basically free 40% performance boost for 4k display owners, thats huge.

Wow DLSS has come a long way. Control was the first game I decided to use it on for a full playthrough, as I wanted RTX on because of how much better the game looked but needed more frames because it's a fast action game. DLSS was good there but I still added on a sharpening filter using Nvidia's game filter that helped it not be so blurry. Is that perhaps what they are doing natively now for DLSS to be this good in Youngblood? Some of the zoomed in comparisons really show a level of sharpness especially on metal grating on the floor that the others just don't have.
Has anyone noticed a problem in the catacombs hub? There are a couple of signs reflected in puddles of water on the floor. The reflection as rendered does not represent the sign correctly as it's missing decals. The sign is blank in the reflection. I think you can see it in Alex's video when he talks about problems with the reflection of a lantern.
I'm curious about how this happens. Is the reflection rendering a different asset or is the decal on the sign rendered in a pass that comes after the ray tracing? Is some thing else going on entirely? Thanks for the video, Alex.

This is simply because the grass animations in a lot of modern games is a shader trick rather than the sprite/polygon physically moving. So the movement is an illusion and the ray traced reflection is only reflecting the real thing instead of the trick. It's not really a limitation of RT but rather a limitation of the grass animation itself.
They use shaders instead of actually moving the sprite/polygons as it's cheaper and allows for a high degree of interactivity, until now the limitations of that trick were not really observable.
Could be wrong about this or how it works but it may be because they simply don't take minor decals into account when building BVH. It's either that, or the decals are added after ray tracing is done.Has anyone noticed a problem in the catacombs hub? There are a couple of signs reflected in puddles of water on the floor.

I assume that it's the most time - and thus money - consuming part of DLSS implementation.
My guess would be deferred decals.Has anyone noticed a problem in the catacombs hub? There are a couple of signs reflected in puddles of water on the floor.

They simply do not exist in representation they trace. (as they are separate mesh used to project image to surface and write their contribution to g-buffer.)
WOW, didn't know that! thanks for the explanation!
Water surfaces use Screen Space reflections mainly for many environment assets, but combine them with RT reflections for close objects and dynamic objects, water is the only RT limitation in the game, I don't why, something to do with the engine I am sure.
Recently jumped back in testing the RT update. I am getting some visual anomalies running DLSS with "mesh" like textures in certain spots and what seems to be, as best as I can describe it, rending delays when panning. I am running the game now with NAS instead of DLSS, when I optimize it via the GeForce Experience; card ran noticeably harder using NAS.
Having said that, been really blown away by the RT performance on my mid-low tier rig running a i5-7400/RTX2060/1080p.
