I really don't think the Switch 2 is the issue here. CD Projekt Red managed to make a Cyberpunk 2077 version that is competent on the same console while it barely runs on the PS4.

If Elden Ring is struggling that hard it's all on From.

We can't act like it's only Elden Ring showing these problems. Borderlands 4 isn't a Solid 30 either according to randy Pitchford. I'm sorry but it's worse for Switch 2 than I was expecting. I thought the games that ran Ok on PS4/Xbone would all be fine on Switch 2, and only the XBSS/X and PS5 only titles would suffer, but that was actually overly optimistic. 1GHZ Arm CPU and 62GB memory bandwidth just isn't going to work well enough for most titles. 

Borderlands 4 is a PS5-XBS next gen only title, so that's a good get for the Switch 2. 

I got to try Madden NFL at a friend's house and it's a lot of fun, him and his son love it, it's basically a portable version of the PS5 game for them and they're thrilled with being able to take it on the go. It does run smoother off the internal storage. They're going to buy a second Switch 2 just because of that, the son will be able to take his own version on the go when football season starts for him with back to school and the dad will be able to take one on his business trips. They also want to get ahead of any potential price increase. People really miss the forest from the trees on a lot of these things.

There will be tons of PS5 games on the Switch 2, quite possibly even Sony's own PS5 titles at some point. Indiana Jones being confirmed and Starfield basically being confirmed by Nate is going to be just the beginning. 

As with any platform the quality of a port comes down to how much effort a developer is willing to put in. Final Fantasy VII Remake Intergrade looks and runs great on the system and has the PS5-lighting too, not the PS4 version. 

If Nintendo wants to ease performance restrictions and let the system clock a bit higher in the future, I think that would be great. The system is watt for watt is a little monster, what it can do with only 9-10 watts is outstanding engineering. I think you will see when the system is inevitably hacked and overclocked that it can indeed run a lot of these 30 fps with dips games at 40 fps and some dips but still above 30 type performance. We saw with Switch 1 overclocks many games easily got 10-20 fps+ bumps in performance in some cases a full 30 fps (Fortnite, FC Soccer, Zelda: BOTW, etc.) uplift, this wouldn't need to be that dramatic. 

Borderlands 4 "ran Ok on PS4/Xbone"? On platforms the game isn't releasing on? Or were these two sentences meant to be disconnected?

This is the current state of released cross-gen titles. You'll have to view in Desktop mode if you are on a phone.

I would hope you could hit 4k, 120fps with a 4090... That's the point of a 4090/5090 tier GPU.

Bandwidth is a difficult thing to quantify this day and age, especially as GPU's get smarter and more efficient with tiled based rendering, compression, procedural generation, large caches, streaming, neural rendering and more.

AMD has managed to match/beat nVidia in many areas with the RX 9000 series vs RTX 5000 series at certain tiers, despite having a significant bandwidth deficit, thanks to sticking with cheaper GDDR6 over more expensive GDDR7.

Bandwidth is only a bottleneck if you make it a bottleneck.

The Switch 2 has fixed and quantifiable hardware that developers can work around... You would sooner be GPU compute bound before you are bandwidth limited if your game is running lots of shaders.

A GPU is a sum of it's parts, not one factor... Which I think is the aspect you are ultimately missing here.

Will the Switch 2's GPU be bandwidth limited in some scenarios? Absolutely. But a games rendering load is extremely dynamic, bandwidth isn't always going to be the limiting factor.

Many rendering loads tend to be "bursty" in nature when it comes to bandwidth demands, I.E. You need lots of bandwidth to fill up the GPU's caches, but then the bandwidth demands drop off, you aren't going to require your chips full bandwidth 24/7, especially once those work sets are loaded into the chips cache.

Everything impacts bandwidth.

However... If you break up your scene into tiles, you need less bandwidth, which is why Maxwell was able to beat GCN.
It's called doing more with less.

Keep in mind the Switch 2 has a faster CPU, faster and more modern GPU which is capable of significantly more advanced effects, you cannot chalk up the image quality gain of hogwarts to just bandwidth.

Many games run at similar framerates as the Xbox Series S... But FPS can often be impacted by the CPU being insufficient, rather than bandwidth.

That's what caches are for.

Remember the Radeon 9060XT has 320GB/s of bandwidth and sits just below the 5060 Ti which has 448GB/s of bandwidth, that's a deficit of 128GB/s.
Which tells us that architectural efficiency is often more important than just unadulterated pure bandwidth.

We could take my old RX 580... I upgraded to the RX 6600XT, same 256GB/s bandwidth, I doubled my performance even at 1440P... I then upgraded to the Radeon RX 9060XT which has 320GB/s of bandwidth, which is an extra 64GB/s... And doubled performance again... That's a four fold increase in performance for only a 64GB/s (Quarter!) increase in bandwidth.

Or let's go back to the Radeon 5870 vs the Radeon 7850.
The 5870 has 153GB/s of bandwidth, the Radeon 7850 also has 153GB/s of bandwidth.

The 7850 can beat the 5870 by over 50% with the same memory bandwidth, regardless of resolution.

Efficiency is often the deciding factor over pure black and white bandwidth numbers.

Borderlands 4 is a Gen 9 only game though, so I'm not sure why you brought up that one?

Anyway, new footage of FF7 Remake seems promising. Not sure what the framerate is here, but it looks fine.

This, From's games are always poorly optimized.

Elden Ring isn't stable even on PS5 and Series X, of course it's going to suffer on a hybrid device that's a fraction the size and wattage. 

Just because it's 9th gen only doesn't mean we can't bring it up with regards to performance issues. Does BDL4 get a free pass to be absolved of all criticism just because it's 9th gen? I'm just saying that now it's Elden ring, in October this topic will resurface with BDL4 release. That's what I suspect anyway

No, but you put it in the sentence after mentioning Elden Ring. If a PS4 game isn't reaching 30, is it surprising that a Gen 9 game isn't?
Almost as if suggesting that Borderlands 4 is in the same generation/category.

"It's slower than a Volvo. Even a Ferrari is faster."

Kinda like that.

I think the bare minimum should be matching base PS4 version's performance. If FromSoftware can't achieve that, it would be bad even per their own low standards. Perhaps the game/engine is heavier on CPU and memory bandwidth where the Switch 2 struggles, and some settings are needlessly closer to the PS5 version.

Some games/engines will just need more time and money to be calibrated for Switch 2.
