Doing less isn't less demanding?
The style is achieved with having to do less work, talking about a conventional painted/cel shaded game as typically employed in current games.
It sure would in realtime! PS4 can't handle photorealism in many cases. Wii U would not be able to pull off a convincing photorealistic scene with dynamic, physically based HDR, translucency, secondary illumination, skin shaders with SSS, etc. Photorealism in this game is beyond the console's capabilities. Going with an approximate realism would probably just be jarring because of the reasons you describe, so a non-realistic renderer allows aesthetically pleasing results within the performance limitations of the platform. I guess what you're saying is that Nintendo could have gone with a
realistic style but it wouldn't have been as comfortable due to the technical limitations in reaching photorealism, so Nintendo spent exactly the same amount of effort not on rendering a crude approximation of realism but in rendering an artistic abstraction.
Yes, I agreed with that, but we're talking about this specific implementation.
Potentially that's true, but it's a long ways off. Realistic people
en masse in realtime with realistic animation in globally illuminated worlds with convincing physical materials is only just happening in the earliest phases of this gen on the next-gen hardware, not Wii U. Wii U can't handle them and couldn't handle Zelda in photorealism. When we get to a point where we can render games with photographic quality, it'll take some pretty bizarre abstract styles to produce a style even more demanding. As you say, the human sensitivity to reality means it requires more effort to pull off, so of course needs more invested in it performance wise.
Oh yeah, its a very, very long ways off.
For Zelda u, I specifically stated the same resource overhead would remain. I also specifically stated it would be less convincing. However, being less convincing is not the same thing as not being able to have a realistic art style be possible at all. Weve been doing it for decades on far less powerful hardware.... And our high end hardware we can pull approximations from are far more capable than what we had to work with back then as well.
Im not arguing that doing less is not less demanding, i am simply bringing up the point that the reason status quo examples are easier on performance is because they are, in fact doing less, when you could very easily be doing just as much, and more so much more (appearence of animated textures that are constantly being painted with brush strokes, to include the texture of the bristles in the paint, and using this to respond to changes in lighting, including all the way down to the subtle surface characteristics and differences in height of the effect of bristles being drawn across a surface), in which case the demand on performance would be the same or more. I know you keep agreeing with this, but its my main argument, the other things I say are just circumstantially attached to it, Im not trying to support the current status quo of non realistic art styles, Im kind of calling them out for being complacent (on platforms with the power to do more.)
In that case I was not talking about this specific implementation, but the belief in general that is being widely perpetuated, particularly by media outlets, and then regurgitated en masse, that realistic assets, shaders, etc are 1:1 inherently more demanding.
Its not the end state I have a problem with, (non realistic games can look as good or better than realistic games while doing less) but the logic used to get there (The reason is not because they are doing less, and that they could do more, but because its 1:1 not as demanding). Its like someone trying to explain that the sky is blue, because its made of cotton candy. Yes, the sky is blue... No, thats not really the reason why.
A recent result of this, for example, being the incredibly irritating rash of erroneous media articles about all the (Non existant) 1080p 60fps wii u games, and how they are only 1080p 60fps because of the non realistic style, and how you now, in fact, should not want 1080p 60fps games on ps4/xbone because of this... When, this was simply just a massive kneejerk reaction to a mistake made in eurogamers review, who accidentally called mario kart 8 1080p.
To that end, I will posit, that Zelda U is a far more demanding game than say, Assassins creed 4 on wii u. Despite Zelda U being a less realistically styled game.
