10% was the general rule as to how much more power the Xbox One will be able to harness with the new SDK that frees up resources that was previously saved for Kinect. So how will this affect games?
One game in particular, Destiny, will benefit by getting a resolution increase. The game will now play at 1080p with a frame rate of 30FPS. That should satisfy those that have been harping on the Xbox One's majority of games that run below the 1080p threshold. The resolution and frame rate will now match the PlayStation 4 version.
I'm sure more and more developers are going to take advantage of the increased amount of resources now that Kinect is no longer a required bundled peripheral for the Xbox One. Good news is we should see some better performing games. The bad news, of course, is the "death" of Kinect.
