On my home network it plays fine in single player applications. I tried playing a game online, it's horrendous. My connection is more than adequate but the input lag is really bad on the controller.
I must be a nitwit... I don't get it... why would you want this?
What does this bring on top of your PS 4 on a 50" TV..?
I have never done remote play before and I managed to get it up and running.
What do I need to set up to be able to do this away from my own network?
May the remote play have a negative effect on the battery life of Macbook Pro in long-term?
Make traveling so much more fun!!
Is it only for downloaded games or can I leave a CD in the PS4 and stream it?
Because it's not going over LAN. Remote play means just that, you can play remotely, away from home. You just need a device that supports it and an internet connection (broadband or mobile).
720p will be fine for most users, especially on a non retina MacBook (like me)
