None of this is surprising. UE5 struggles in general, on all platforms. And like the Virtuos dev said, in these GPU intensive titles Series S is going to be running at 60fps where Switch 2 does 30fps. 

This is still a smaller gap than Switch and the PS4/One, where games had to be largely reconfigured and optimized to run decently on Switch. 

Yea i think everyone expects the gap to be much smaller. PS4 games still good today while Switch 1 ports from ps4 mostly look horrible.

None of this (bar the splitscreen) sounds like struggling to me because its very much what I expect for current gen games. 

1080p(upscaled)/30fps output.

The achievement with S2 is the fact that it's receiving these games in the first place IMO, mainatining the actual vision and in a timely manner. The last 2 points I think is where things will really matter and I'm curious to see how it pans out throughout the generation. 

It's only with smaller scope or last gen games where it's reasonable to expect S2 to sacrifice only resolution and some graphical detail and essentially offer a slightly doowgraded version of Series S 

The no split screen is unfortunate, probably possible but just such low priority for the team

Yeah, the low response time is a real issue that exists and it's there, but if you can notice it or care is another story. 

Personally I can barely see it. I noticed the coins in Mario Kart leave a trail behind them, and that was it. On everything else I played I tought the screen was fine.

Like with most things, it's gonna depend on the game in question; Split Fiction on Switch 2 is actually pretty solid given its roots on more powerful hardware. 

Cronos The New Dawn and Daemon x Machina Titanic Scion are also UE5 titles coming quite soon, it will be interesting to see how they turn out. Looking further ahead there's also Reanimal.

UE4 was pretty heavy on Switch 1, but it still produced good results in games like Pikmin 4, Ace Combat 7, Bright Memory Infinite, Dragon Quest 11, Rogue Company, etc.

I remember a while back I was predicting the Switch 2 to be something like a GTX 1650, with the Series S something like the 1660 Super. That is pretty much what we're seeing here in terms of performance difference. Basically games that run 60fps or variable 45-60fps on Series S will tend to run 30fps or variable 30-50 fps on Switch 2, unless they are older and not really pushing the Series S. Some very minor compromises will be made, and typically when a compromise is made on one platform it is also made on the other (with a few exceptions -- i.e Fortnite having Lumen & Nanite.) 

This gap can be bridged in some ways with DLSS, as well as the memory capacity advantage for Switch 2 and as developers become more familiar with the platform, but that is pretty much the typical gap. 

I really don't consider  Switch 2 receiving  current gen games  a achievement. PS4  received 2 massive open world games that came out on current gen and ported later, and they look more demanding then these games.

Most people expected 60fps for Sparkling zero, Madden and Fifa. Lumen and nanite were expected as well for Fornite. People keep saying it's closer to Series s yet there are no games that are demanding that run double the frames of PS4, nothing comes close to the gaps were seeing between Series s and switch 2.

As a handheld, NS2 is quite good - it's the docked mode that could've (and should've) been better - putting active cooling in the dock (that actually cools console, not the dock), could've easily see clocks go up by at least 30% than they are now, if not more.

Almost like memory bandwidth is an issue, like I've been saying for almost two years.  

And yes the gap is significant, which I personally expected.  I never bought the nonsense that the S2 was going to "trade blows" with current generation home hardware.  

Still powerful for a mobile device.  

It does trade blows with Series S though, such as being able to do better textures thanks to more RAM, or better image treatment thanks to DLSS.

"Trading blows" doesn't mean they're the same.
