Just tried streaming, works fantastically well for me considering both platforms are effectively still BETA.
XO is connected wirelessly to an AC router, Windows 10 (a little Celeron BRIX system which I didn't think would handle the video encoding) is wired to the router.
Forza Horizon 2 loaded straight up, played it fine with a wireless x360 controller, rumble as well. Only thing that didn't work is the guide button isn't mimicked which is weird, so had to use the mouse to select that from a toolbar. Had my XO pad turned on though next to me which I had taken upstairs and that continued to rumble at the same time as the other pad which is funny.
Bandwidth seemed to max out at around 16mbps at the highest setting, plus I could snap the window and have something else running at the same time
As with PS remote play or PS Now you can tell it's a video stream as there is a bit of artifact, but I'd say it's slightly better than the Sony solution.
