These performance checks are very useful for some people, but as an actual gage of what the Wii U can potentially do they're obviously off the ball. As an analysis of what it is currently being achieved in multi-format games (handed out to smaller, inexperienced developers) it tells us quite clearly the Wii U versions at launch aren't up to scratch.
Given we've 'known' for months that Wii U was in the same ballpark as current HD systems, given the historically weak third party support for Nintendo, the historical poor track record of third party ports in the launch window of consoles, I have to wonder why anyone is acting surprised or outraged at this point. Any developer struggles to optimise their game for day and date release on a new console, even if that console has similar architecture to existing consoles. They'll only find it more difficult to optimise when they're taking code they didn't even make themselves, as is the case with this game, and shifting it to a system they have no experience of developing for.
I'm more interested in Assassin's Creed 3 and Colonial Marines when it comes to a DF analysis, because those games come from companies that have very publicly, very often announced their support and positive experience with Wii U hardware. Gearbox love the Wii U hardware and Ubisoft have invested massively in the system, so we should expect strong results from those games. All the signs are that Ubisoft and Gearbox are actually optimising their multi-platform games for Wii U, meaning we should have a better picture of how Wii U can perform relative to 360 and PS3.
As it is, these comparisons and the outrage associated with them shouldn't matter too much in the long run. The real test of Wii U's capabilities, and the real test of its mass market potential, will lie in the exclusive software and services, which to all intents and purposes, are so far pretty decent. Like I said, these articles are useful for some people, but they aren't really indicative of what the Wii U can genuinely do, and I doubt they're going to change the opinion of anyone whose already dismissed or bought into Wii U--they're indicative of what third parties can do with late, low-priority ports in time for the launch window, and I have to ask, was anyone actually expecting a good result?
