Oh well ok you got me, Switch 2 is ARM based, I am wrong there.

As to differences between APU and GPU drivers?

Nah, not really, at least not on linux.

That the Switch 2 is ARM based is probably actually significant.

You would basically have to port an 86_64 game over to ARM, potentially redesign a whole bunch of the game’s core inner working systems.

Again though, yes, there are big differences between a full PC GPU and an APU… but there’s far less difference between a laptop GPU and APU, in terms of compute power per physical volume, and many laptops can run Elden Ring just fine.

The Deck and Switch 2 both have APUs… only one of them really struggles with Elden Ring.

And yes, the Switch is a potato compared to even a low-mid tier gaming PC.

It is also a potato compared to a Deck:

I have yet to encounter a Switch 1 game I cannot emulate on my Deck, with worse than a 10% FPS drop from what the Switch itself gets natively on that same game.

Used to be the case that you need a pretty beefy desktop PC or laptop to emulate last gen consoles.

Uh nope, not anymore.
