If you have got the latest software update for Xbox One you will notice that things seem to be much smoother. One thing that is noticeable is the Kinect seems more responsive and smooth. It seems like it hears you better really clear now and is responsive. The UI is smoother and responsive and added some nice new features like storage management and friends and party changes for the better. They also did some performance increases on the back end for better game performance so we should see games running better soon and with new releases.
MS has another planned update in march right before Titanfall that is said to further improve things and added performance. This is all before the new SDK kits hit developers to offer much faster dev tools and said to make it easy to hit 1080p in games moving forward.
Great job MS keep up the great work your doing what you do best and that's software and performance updates we all know you will be OWNING the competition this gen once again with this. Great work.
