I’ve been doing a ton of testing with Remote Play on the PS4, using my Vita, and the results are pretty positive, but not perfect.  In my testing, I had a 5 Mbs upload with Time Warner which is causing any issues that you see in my videos.  On games that aren’t visually intense it’s not too bad, but on NBA 2K14 it definitely hampers things.

Another issue with Remote Play, are the actual controls.  The Vita just isn’t good as a controller, and it’s a shame, because Remote Play is a great feature that’s hampered by awkward controls.   The Vita doesn’t have an L3, R3 that have been standard in most controllers for a decade since the PS2.   The back touch screen means that you have to hold the controller awkwardly or risk activating something you didn’t mean to.  Perhaps I just need to get used to the Vita, but it feels like I have to get used to using a poor design.
