Although the Wii U is most definitely a high-definition console, it looks like it may not even have the horsepower of the PS3 or the Xbox 360, according to one anonymous developer.
In a message to GamesIndustry International, the anonymous developer stated that
No, it’s not up to the same level as the PS3 or the 360. The graphics are just not as powerful.
Another developer that wished to remain anonymous echoed these statements, stating that
Yeah, that’s true. It doesn’t produce graphics as well as the PS3 or the 360. There aren’t as many shaders, it’s not as capable. Sure, some things are better, mostly as a result of it being a more modern design. But overall the Wii U just can’t quite keep up.”
Nintendo is no stranger to releasing under-powered hardware: The Wii’s graphical and processing capabilities were obsolete the moment it hit the market. At the very least, it’ll be nice to see Nintendo-developed games in 720p/1080p, even if that means we might notice graininess here or there. Nevertheless, I suppose this may inconvenience third-party devs that pride themselves on creating technically-advanced graphics engines, like Epic Games and id Software.
