Nvidia DLSS doesn't require the internet. It can be done in hardware.
As for the thread, for a Switch 2, DLSS 2.0/3.0 would absolutely be a huge game changer. Switch 2 could render at native resolutions even significantly lower than the current Switch has to and achieve an end image quality comparable or even better than 900p-1080p undocked and 1800p-full 4K docked.
If effectively reduces the number of pixels the Switch 2 has to render by 1/4th, and who knows with DLSS 3.0 eventually that could get even better.
I would have no problem in believing a Switch 2 being able of 1080p30fps or even 60fps for some titles. But 4k120fps and you question me over OP? Not even PCs will do it for demanding games in the next couple years but he expect Switch2 to do it, yes sure.
