Well, you remember wrong then. Most people were surprised to even see the game running on the Switch. And as such, almost everyone expected 30fps. Those who expected 60fps were almost non existent.
Zelda only drop frames on big cities. On portable mode, it doesn't even drop on those. That's not struggling. End of the story.
I don't remember wrong, but it doesn't really matter.
There is hardly anything going on here, and i see frame rate dips.
another video showing stressing areas with massive frame rate dips.
On the first video... you think that ocasional 1 frame dips are enough to say the game struggles? Ok, I see there's no point in trying to reason with you.
Oh, btw... about the second video, which is the one where the game actually shows heavy slowdowns. First, as I said, it only happens on the big towns (and the kokiri forest). And second... if you could actually put one and one together, you would have noticed that the second video is from version 1.1.1 while the forst one is from version 1.2. And... surprise, surprise: Kakariko Village is shown in both videos and while in 1.1.1 it shows heave drops, in 1.2 it shows NONE. And that's version 1.2. Now we are at 1.6, which is nearly perfect in both handheld and docked.
Next time put a little effort into your evidences. I have nothing more to say to you.
