Was up for me at 10pm... just been playing Destiny via streaming to laptop.... FANTASTIC!
Yes, there is slight input lag, so obviously not a thing to use in multiplayer, but wow, I didn't believe it would be this good!
Some tips though!
Don't forget to change the quality depending on your setup!
I was using wireless, in the same room as the xbox. So, after messing around for a bit I found medium quality was ok for the most part. A little input lag, but decent quality stream. Low quality was great lag wise, but is also a little blurry. High quality was pretty good looking, but lag was more noticeable.
Impressed!
