Kinect uses "less than one per cent" of the Xbox 360's CPU power, Ubisoft's internal "Kinect expert" Frederic Blais has told Xbox World 360 magazine.
When quizzed on recent rumours that Kinect uses as much as one entire CPU core to run, Blais said: "That's not true at all. I don't really know how much I can talk about it but it's less than 1% [of the CPU's power], or something like that."
Blais claimed Kinect's CPU usage is so low "we could apply Kinect to an action game and still put the same kind of action on screen".
According to the Ubisoft man, triple-A Kinect first-person shooters that use both camera and controller are possible, but we're certainly not seeing any in Microsoft's line-up at the moment.
As for Ubisoft, Blais said there's some stuff it's "thinking about" in this area.
"I think that technology's really cool when it's faster than a controller, or you do something that you can't do with a controller. These are the rules of Kinect design," he said.
"Think about a hardcore game like Rainbow Six where you're doing hand signs and stuff like that. It would be cool; it would be more immersive. We'll have to see if hardcore gamers will be ready for that."
