Major Nelson's stream was broadcast at a resolution of 1280x720, while Twitch streams on PlayStation 4 weigh in at 960x540. Both platforms output at 30fps.
Additionally, Xbox One Twitch streaming will not broadcast audio from Party Chat, and streamers can see chat and viewer statistics without them being displayed on the stream.
The Xbox One will also allow streamers to archive their streams, which is a much-requested bit of functionality the PS4 currently lacks.
Twitch streaming on Xbox One will roll out with the platform's March update, which promises to improve, among other things, the Party Chat experience. Microsoft is making no secret about the fact that it's implementing these features to make way for the launch of Titanfall on March 11.
