What they were talking about being from Halo 5 was that the 3d models which are a distance away from the character are animated at effectively 30fps rather than 60, not the 2d model part. Unless I'm very much mistaken but that looks to be where they are talking about Halo 5

Yeah and the thing everyone has to remember with this, the game isn't out for another 4-5 months, if there is things like asset streaming issues that could be because the code is all over the place right now and the assets are not arranged in a method which is fully optimised for the Switch to work with, by the time the code for it all is cleaned up and everything is perfectly in place and streamlined for launch then we could undoubtedly see things getting better by launch :) it's months away.

Hopefully I keep being blind and don't start looking for it lol. The methods they're using to reduce GPU load are quite clever though, especially in handheld mode.

I believe your right. Thats what im referring to. The further characters get away from the screen they look like they have animated movements at 30frames. Which is very noticeable when you know its there and that the game runs at 60 frames. Its not going to stop me from getting it however its just annoying.

I dont think I have ever played a platformer since the sns that input was so critical.

I'd definitely prefer 1080p docked, but as long as the frame rate is solid, I won't even notice once I've played a few minutes.

Yeah the models have 3 different modes at the E3 demo, 60fps when right near Mario, 30 fps when they're about 30 feet away, then once they're further away again they become 2d sprites to represent where models might be (but weren't lined up right in the demo in areas) It sort of reminds me of the distant car lights on the roads in GTAV (at least on the X360 version of the game) they were literally just lights in the distance, not cars, it was a clever effect to try to give the illusion of the game being able to be more... alive than the system allowed, the same is at work here.

ARMS and Splatoon 2 also ran at 720P initially when docked, but both later recieved a resolution bump (both went to 1080P @ 60 FPS; although ARMS will go down to 900P in splitscreen). Based on this track record I think Nintendo optimizes for portable mode first (where the screen is 720P and the GPU is underclocked and so that becomes the target resolution and specs respectively) and once they get that down they then focus on increasing the resolution in docked mode. As such, I imagine the demo they showed will also run at 720P while in portable mode, because that is what they are optimizing it for first.

720p60fps, that's what I thought when I saw the trailer

OK I know why this game looks and feels weird to me...

It's more akin of a Banjo and Kazooie or DK 64 than a Mario game.
