New Japanese footage of the PS4 has appeared from an unknown event showing how the PS4’s Interface works, including multitasking and Remote Play. The video shows how seamless it is switching between a game (in this case, Knack) and the web browser (or another application).
The video also shows how the PS4 Link application works, which was recently made available in PS Vita Firmware 3.00. Knack is played on the PS Vita via Remote Play from the new PS4 Link application, but it’s difficult to see how the quality of the game compares on the small screen.
