When development starting maturing it was dropped as unnecessary. Kinect now tracks less than it did a year ago but that's tech efficiency.
"We didn't know how much processing Kinect was going to take at the start of development," said Kudo Tsunoda, the man who claimed . Microsoft claim that Kinect uses less than a percent of Xbox 360's own processor.
"Obviously you don't want to lose any of the things that are important to Xbox customers. Graphic fidelity is something that Xbox has always been known for, and you want to make sure that you still hit that level," continued Tsunoda.
"Forza is a graphical showpiece, and we had Forza with Kinect at E3... the graphic fidelity has actually improved in some areas from what they shipped with Forza 3. It's still running at 60 FPS and it's supporting Kinect, so there's just no need to have that extra processor."
The motion camera now also tracks less points on the human body than it did a year ago, but that's not sacrificing performance as they realised they could accomplish what they needed but with less - much like the processor getting dropped.
"As you start building the stuff, you're like: 'Wow, to track everything in the human body we can do less points. That's just normal game development. Anything you do with games, you want the processing power to be used as efficiently as possible to get the experience that you want," he said.
Kinect retails November 4th in the US and the 10th in the UK.
