Project Q is the upcoming streaming only device that will allow you to play games installed on a PlayStation 5 remotely.
It has not been announced if the handheld will allow streaming of games from the cloud and is rumoured to cost between £250 - £300.
Will you be picking one up later this year?
I use Chiaki4deck to play golf/adventure/strategy games. The input latency is less forgiving in racing/fps/survival genres.
