Makes sense, but woulnd't 1440p 60fps would be more feasible for native, meanwhile DLSS can to the work for 4k.
Yes, but the original question was “could this be done natively, without DLSS”
I mean yeah, I'd be genuinely shocked if it couldn't. It would hardly be worth it if botw couldn't at least theoretically do that.
I mean, a system neck to neck with the Steam Deck, being able to run BotW at 4K60...
The two genders: "If Nintendo can't do X, it's hardly worth it" and "No way Nintendo will go as far as X." Prepare to both be genuinely shocked.
Let's do this with as little tech deep dive as possible, and just some simple arithmetic.
1080p is 2 million pixels. 4k is 8.3 million pixels. That's ~4x as many.
But
Breath of the Wild doesn't run at a full 1080p, it is a dynamic 810-900p. 900p is 1.4 million pixels. That's 6x as many pixels. For a 4k
Breath of the Wild we need 6x as much power.
We have leaked chip specs, confirmed by multiple outlets. We know that the chip in the Switch 2 has 6x as big a GPU as the original Switch. Simple.
But that is just 4k -
Breath of the Wild is 30fps. To get there natively, we'd need to do twice as many graphics calculations a second - 12x, instead of 6x. That's why I'm certain Switch 2 can't do 4k60 natively. But that
native is key - we don't need to get there natively! The rockstar feature of Nvidia's cards is DLSS, which augments native rendering.
I'll skip how DLSS works - I'll just say that on even the most hamstrung of tiny laptop cards, DLSS roughly doubles the expected frame rate of native rendering. That is your 60fps.
...with 0 loading times ?
Yes. Most of loading is decompression. Switch 2 is known to have custom decompression hardware, like Playstation and Xbox. It makes decompression effectively instant. That's something that doesn't exist in PCs, which is why something like Steam Deck, which is just a mini-PC, doesn't have it
If you make a console with a bunch of cool new hardware features, you'd expect your in-house engines to take advantage of it. And if you did that, you'd probably start with an existing game, so you're only solving one set of problems. And if you were to take
Breath of the Wild, and adapt it to use the tech we
know is in the hardware, then a 4k60fps, zero loading time version of the game is
exactly what you'd expect. Almost weirdly to a tee, in fact.
A modded switch at standard tegra X1 clocks can already technically hit 60 fps as it is.
I don't know what you mean by technically, but if you want to consistent 60fps, you need a 2.3Ghz overclock, which is not only well beyond the stock Tegra X1 clock (which was only 1.0GHz) is beyond what the original TX1 was even overclockable to.
Which makes sense. You need to add enough power to hit the max res + double the frame rate. That's about 3x as many pixels, 2.3 GHz is basically 3x the 768Mhz base clock of the Switch. Exactly what you'd expect if everything scaled linearly.
