The stream isnt 60fps. I have it on a second screen and i'm not watching that much, so it could be bad, but if you are seeing a constant 30 it's the best you can see from this stream.
Yeah I just spotted that. It looks like a very consistent 30. Certainly, gameplay I've seen before now has been 60. Why aren't they using a 60 FPS stream? 720p 30 in 2017 is poor.
***EDIT***
Yeah it's the stream he just said 1080p60 docked 720p60 undocked.
