After seeing that Hogwarts Legacy scene, the one that later DF talked about in length, I was very surprised at how bad DLSS is doing on Switch (and it is DLSS, according to official press release), compared to PC counterparts when it comes to disocclusion artifacts. Honestly, it looked like its temporal data is scaled down a lot, and that's what's producing so much disocclusion artifacts. So, I'm quite curious to see, as someone who plays lot of games with DLSS upscaling, what exactly SW2 solution is doing and what it can pull off.

The Switch 2 isn't a powerful system so is upscaling from a much lower resolution in order to create it's 1080p portable visuals but its also only a 7.9" screen so hopefully most artifacts won't be as obvious. Many PC games are using DLSS at a much higher native resolution so its a much easier upscale. I have to say though DLSS on Switch 2 looks amazing compared to FSR 3.2 on AMD graphics hardware, if you think DLSS has artifacts you can't have seen FSR 3.2. Switch 2 seems to be doing an amazing job overall in upscaling but ultimately its guesswork upscaling which will go wrong on occasion. It's never going to be as clean an image as a pure natively rendered image at the same resolution. I'm sure where possible i.e puzzle games and more classic arcade games the Switch 2 will just natively render at the higher resolution.

Not sure if you watched the video, it was very noticeable, and some days ago DF did an episode on Hogwarts where they've discussed that very scene - standard DLSS 3/4 just doesn't look that bad in 1440p in any setting (and that is resolution Hogwarts is supposedly outputting, in docked mode), so it is very weird that it does on SW2 - as if it has reduced precision or a shorter accumulation window for temporal data, which is why disocclusion artifacts are pronounced so heavily.

So maybe there's actual SW2 Ultra Lite DLSS after all, that cuts back on some stuff to be much lighter to run, but in return can't handle some problems as well as standard DLSS. (again, do watch DF video, starting at around 13:15, at full screen preferably).
