Easy: 30fps with some drops here and there to high 20s and to the low 20s. With a 720p on docked and a dynamic resolution on portable mode that ranges between 640p and 480p and all the obvious downgrade it will have, that's what we'll probably get...

I don't ignore you. Don't you think that you're so important.

Yes its struggling it drops frames with basically nothing going on. Not struggling means it's nearly locked. obviously zelda BOTW is not anywhere near that. Not saying the game is not mostly 30fps. Drops are common though which means it's struggling to maintain that 30fps.  

Also the first video shows 5 seconds of Kakariko village not exactly a valid comparison.

Hahaha, important or not, you're funny with your answer. Even base Xbox 1/ps4 only have 30fps with some drops to mid 20s in some areas. Now Switch which is at least 5 times weaker than base Xbox 1/ps4 can do the same? Nice logic here. Hope you didn't forget FFXV Pocket Edition case. Inb4 The Witcher 3 Pocket Edition...

Emm... do you realize that PS4 version is 1080p and XOne is 900p... and that both have medium/high PC settings right? An hypthetical Switch version would not only cut resolution to 720p, but it would also have downgraded visuals that would go even lower than the low PC settings. And just before you say that if the go below low PC settings it will look like shit, DOOM also uses visuals below low PC settings and it still looks fine.

With those changes, I don't see why it couldn't run a 30fps with some heavy drops on busy moments.

the games file size is close to 100GB on the PS4 it would take an incredible amount of work to make that any way feasible on the Switch.... I guess Doom was in the 80GB region and that came down to 25 or so on the Switch but the id tech 6 engine is known for its fantastic scalability, the REDengine I'm not so sure about given the fairly poorly performing Witcher2 on the X360, I would definitely just take this as a rumour and not much else and if it did turn out to be true, I wouldn't be pre ordering it until I seen how it runs and how much SD card this would require.

You are making it sound much easier then it really is. wolfenstein 2  and doom both targeting 1080p/60fps on base ps4, both run mostly below sub HD resolution/lowest settings, and had the frame rate cut in half on Switch. Id tech 6 engine is also known for its great scalability. It really is a gigantic task. I would love to see it, but people are doubting it for good reason. Switch also has 50% weaker CPU the current gen, and open world games rely heavily on that as well. 

That was what i meant, that I can't see them bothering to essentially rebuild the game for the Switch, which is what would need to be done.

And hence "like current gen, just blurrier"; Wolf 2 and Doom on Switch retain almost all of the PS4 tier rendering techniques of the PS4/Xbone versions, just at a lower resolution and framerate. It was probably just easier and cheaper to do it that way than to extensively rework it.

It's actually not that bad, Witcher 3 + DLC + Updates on PS4 takes up about 75gb. But funnily enough Witcher 3 GOTY installed on PS4 takes up only around 45gb. PC installed with all content is apparently about 51gb. So I think they could get it down to anywhere from 24gb-32gb if they wanted.

Actually the PC port of witcher 2 for 360 was a stable 30fps. it was pretty impressive at the time, even though its not even a great looking 360 game now.
