digital or not, I'm pretty sure the game is not converted and ported just yet, usually they do that when the game is done like a month before release. people need to do some research if this is their hobby.

I knew those mature guys holding those tiny controllers looked fake and out of place.

why not ?

this reveal ad is/was the most important, market defining moment for the Nintendo Switch and I'm sure Nintendo made sure to have plenty budget/resources (as in dev output) for that

that's what I was thinking when I read the quote

That's why there's a question.  If you're just putting footage in post production why would you use 12 fps footage from a game that has never been shown to run that poorly before?

because one of the actors said that everything was post production. also,  to run a game in development you need a debug console or a demo, not a normal switch used for advertisement. In what world a company, sony, Nintendo or ms are going to port a game that is not finished or going to code  a demo for 10 seconds of screen time?

That's not how it works. Running a game in debug mode on a dev kit vs running it in retail mode is literally a matter of a setting on the dev kit/deployment tool. Also, running a game in debug mode typically displays all kinds of debug information on the screen so you can see things like frame rate, and memory allocations in real time as the game does its thing in real time. We don't see that here. It normally doesn't run the game slower unless you specifically set it to run slower for debugging purposes. That's the main reason why dev kits are more powerful than retail kits - so the debug tools can be run on top of the game itself running at normal speed, using all of the resources it would be using as if it was running on retail hardware . There is no reason for this game to be running at 12 fps just because it's a pre-release build of the game.

This game is already in beta. It's at the polishing/finishing touches point. This game should be running at at 24-26 frames per second at minimum at this stage in development. Not 12 fps.

I have same question, doesn't change the fact that was a post production. Maybe bad editing or bad footage choice? We see the game running well on tv, and then 12fps on the device, but that should not happen because the dock is just a dock and the game was "running" on the device when was displayed on the tv. So yeah, many, scenarios, not just "the game runs like crap on the thing"

What the hell... Does that mean that Mario footage is not real?

That could just mean that not all games have to look or work exactly like on the trailer, because they are not even done.
