About this I think it's likely PSSR uses ID buffer hardware still there on PS5. What do you think? Shouldn't it help with the rest of the AI upscaling pipeline?

I don't think it does. First, you don't need to rely on the ID buffer to cull irrelevant history with the neural network. The NN will handle that. Second, outputting the 32 bit ID buffer is exactly what developers would typically avoid to save bandwidth for performance reasons.
TAA was necessary. FXAA, MLAA, MSAA etc. looked terribly pixelated and noisy. I prefer smooth and stable images. Ryse with FXAA? Please not.
TAA is also available in varying degrees of quality and sharpness. The Division 2 looked quite sharp and flicker-free.
I also preferred the more aggressive TAA from Battlefront 2015 over that from Battlefront II. Battlefront II flickered more while Battlefront 2015 reminded me of a film. The same applies to the Battlefield games where the flickering increased compared to Battlefront 2015. It needed DLSS to reduce that issue.

Not sure how you can say MSAA looks pixelated and noisy.
Ryse also had a TAA option that looked like someone had rubbed Vaseline in your eyes.
MSAA mostly only worked on geometry. Textures, Normal Maps and transparency textures like vegetation flickerd a lot. Screenspace effects also often looked bad with MSAA. MSAA costs a lot of performance while TAA comes nearly for free.
If there was no TAA I would have stopped playing games already, I can't stand the flimsy and gamey look of FXAA etc. Getting the TAA mod to work in Alien Isolation was always a priority for me.

MSAA does nothing to reduce surface aliasing and flickering which is rampant nowadays. It only worked on geometry edges.

But it's not just the edges that it smooths, it's also per game dependent, some games don't shimmer as much as you think with no aa.
Just having the option to turn it off would be nice (with a possible performance hit of course)
That way you're free to play around with things like down-sampling, which I have done in games like Dying Light 2 with TAA disabled.

Yea definitely should have an option to disable. I mostly play older games so use DSR a lot and will use DLAA in newer titles when possible.
Yea true. That's always been my solution to the problem of inner surface detail loss with TAA... basically just throw more pixels at it. I often game at ridiculously high resolutions and realize that not everyone can, or wants to.. but yeah everything is very content/game dependent.

You also don't need that much down-sampling to deal with the vast majority of shimmering and shader aliasing in games.
On PC that's easy, but on a console, even 10-20% down-sampling is a lot of performance to find.
I like things REALLY stable though
That aliasing you see in motion is the aliasing in the depth and velocity used for reprojection of previous frame data. UE 5.5 has a new reprojection field (r.TSR.ReprojectionField) to fix that: https://github.com/EpicGames/UnrealEngine/commit/a25896107ee63bdbb7c27d09379f3bc2d7d9cddd
Running much better with ultra boost mode?
That's some great work here, but I was referring to a different kind of aliasing, mainly listed here. Wonder if spatial AA is applied in dissoccluded areas for UE5 (and in which branch). if you have a directional spatial upscaler in the TSR, such as FSR 1.0, prefiltering edges in previously occluded areas should help eliminate aliasing and improve quality in the regions where there is no temporal information. Another approach I prototyped for fun as a weekend project was repurposing the MLAA algorithm for high quality spatial edge upscaling. Although there is some artifacting here and there (which I know is easy to fix but requires time), it works really well in combination with nearest neighbor upscaling for preserving contrast. Wish GPUs could export high res coverage sample mask at a few bits per pixel. Pixel perfect spatial upscaling would then be a trivial task == no low res aliasing on edges in motion.
TSR has a spatial anti-aliaser built-in since the Matrix Awakens and 5.0 that happen on any history rejection (whether disocclusion or shading changes): https://dev.epicgames.com/documenta...ne/temporal-super-resolution-in-unreal-engine
That is that built-in TSR anti-aliaser that the “technical” journalists got the rendering resolution of the matrix demo wrong ending up giving a wrong first impression of that tech.
The difference between TSR’s aproach than FSR1 is that: the former approach is analyse the aliased image at rendering res kinda like FXAA, but where FXAA will directly applies the anti-aliasing immediatly, TSR only defer the application of the spatial anti-aliasing in the same and unique upscaling kernel to display resolution. This avoids the problems of the latter where FSR1 style upscaler has to basically waste GPU cycles figure out what your prior spatial anti-aliasing just did spent GPU cycle on.
