Please, Nintendo, if you're going to do VR wait until you have a console powerful enough to handle good resolution + good framerate.

I don't see how that's relevant.

Cellphones can handle VR.

Because VR run on low resolution screens at low frame rates makes people sick. 720p is inadequate. The PSVR is 1080p, and runs at 90hz and many people have complained that the poor resolution and poor frame rate has made them sick. How would a 720p screen running at a lower frame rate, fare any better?

720p is more than adequate. Virtual Boy was bad because its only two colors were black and red. 720p is only an issue because of the screen door effect, which won't be a deal breaker for the mass market at a cheap price and there's absolutely no reason to believe that framerates would be bad. It definitely wouldn't make people more sick than better devices. The only difference is the level of immersion.

A 720p VR screen running at 60fps would be more than fine. All it has to be is good enough for cheap enough.

Ok, you've clearly never used VR.

A 720p screen may be ok for everyday use, where the screen is at an arms distance from your face.

But when the screen is strapped to your face, the individual pixels are not only seen but make it so that you can't even read text on it.

Using the PSVR, if you attempt to read anything except pretty decently sized fonts it's damn near impossible (and we're talking about a 960 x 1080 per eye at 90 Hz. 5 minutes on a VR screen of 720p quality would literally make your eyes bleed.

One of the reasons why VR is so demanding physically is because your brain has to constantly compensate for some poor image quality that comes with it. It needs to constantly try to ignore the individual pixels and build a smooth image for you.

All of this is assuming the machine would even be powerful enough to run any game in VR, which it isn't.

Oh and before you say "but phones..." again, every phone that has some form of VR has a much better and higher resolution screen than the switch does and their main purpose is for VR video, not gaming. And even at that they are pretty poor (I know, I have and S7 edge with Gear VR)

"Once it's right"
So never. You just can't do VR with those specs.

Why would it be at a lower framerate? My biggest frustration with any VR discussion is people saying Switch is too weak or it cant handle it. Art style, direction and game design is a choice. Its why MK8 delux is a solid 1080p 60fps whilst most pS4 games only dream of that  kind of performance.

VR doesnt need to be a realistic AAA wannabe in order to be inmersive, deep, exciting and fun. This understanding is why I think Nintendo will probably be the first to make it mainstrean. Although I agree Switch 2 will probably be the best time to introduce it due to the  Switches screen resolution.

720P and 60fps is NOT fine for VR. You should try using VR some time.

Correct to a point.

But I think you are underestimating how difficult it is to achieve 90fps... Especially for a chipset that has multiple bottlenecks that would prevent such an achievement without significant compromises in fidelity.

Plus, Mario Kart 8 Deluxe only achieves that resolution whilst it is docked and connected to mains power... Plus Mario Kart 8 isn't exactly a great game graphically.

Mario Kart 8 looks great in my opinion. Sure its not blow you away "pretty" by 2017 standards but its not exactly an eye sore either. And I'm only using it to reinforce the point a point about designing visuals and game worlds around a target resolution & fps. VR is about an immersive, compelling experience, this doesn't begin and end at how graphically impressive a game is or how much ai/physics etc you can fit on screen. People setting their sights first on those ambitions and latter on accessibility and gameplay is something that will hold VR back. The first VR game I played was an ugly rollercoaster simulator, it still blew me away. I'd rather play a game that looks and plays like a slightly more polished Metroid Prime 3 in VR than anything I've seen on PSVR (although REVII looks amazing). 

If they just implemented some AA and used simpler textures which don't scale poorly, this would be perefectly acceptable for a VR experience. This is a game that is natively 480, 60fps on the Wii specs which only marginly better than the 2001 gamecube specs.
