DLSS SDK was bumped to v2.2 with the release of DLSS in R6S.
Haven't seen anything on changes compared to 2.1 anywhere though.

People were reporting 2.2 eliminating ghosting in games. I did a quick test with UE4 debug camera. It draws this line to indicate what direction the object you are looking at is facing. I remembered the line ghosting severely with DLSS 2.0/2.1 as the camera is moved. I'm just moving the mouse up and down continuosly as I take a screenshot here:
2.1:
2.2:
Took a bit of effort to get 2.2 to draw that single ghost as clearly as it's showing here.

Wow, that's a huge improvement. Should have less ghosting than TAA now in most games, which means the ghosting issue is fixed.
I would love to look into it, but I don't have R6S. Will wait for Doom Eternal which probably will have DLSS 2.2 too.
I tried using the DLSS 2.2 DLL with Metro Exodus EE but then DLSS won't enable.
Hmmm I thought the issue with DLSS ghosting in death stranding was due to lack of motion vectors on those objects.

Nothing points to that not being the case. The 2.2 update seem to work around this issue somehow.
From the screenshots, it looks like DLSS 2.2 in Death Stranding just slowed the birds by quite a bit 
Well it does raise the question of whether the problem wasn't actually motion vectors but a bug in DLSS that is now fixed.

I don't have a DLSS capable card so it's probable that my overall impression of it is being skewed as these videos are designed to highlight the scenario's where 2.1 falls down, but gotta say after seeing a lot of these comparison videos between 2.1 and 2.2 I'm leaning towards seeing that poster's argument who was arguing that DLSS's flaws were being papered over. I mean a lot of these ghosting artifacts seem pretty egregious!

These ghosting artifacts are there without DLSS too you know.
Why are Nvidia not shouting about this? Seems like a major upgrade to me.

Well, maybe they plan to say something on 22nd to counter FSR.
Or maybe it's not such a big upgrade in their opinion.

Certainly not across the board. Definitely not in the Death Stranding comparisons I saw for one - the birds and cryptobiotes do not produce those trails without DLSS, and the edges of the geometry have ghosting that not even checkerboarding has (as per DF's video). I realize the explanation of the time was that some of those objects didn't have motion vectors, but I see pretty prominent artifacting around the wires/poles from these videos, which 2.2 definitely reduces (though not entirely).
Death Stranding 2.1:
Death Stranding 2.2:
Cyberpunk is another comparison where 2.1 showed significant trailing from the car lights when driving around that 2.2 helps reduce quite a bit.

Every game with TAA have them to some degree. DLSS may increase some of them but it makes other less apparent at the same time so it's a draw. If they've managed to lessen them to a degree in 2.2 then it would just make DLSS even further better than your typical TAA.
Interesting question. I would imagine doing something like 720p->1440p via DLSS and then 1440p-> 4K with TSR would lead to crazy performance.
TSR and DLSS are substitutes. TSR needs the same inputs that DLSS uses so I don't think it would work to chain them one after the other.
