Just download the free Elgato software, plug the PS4 HDMI into the Cam Link, then plug Cam Link to a PC’s USB 3.xx slot. Record game footage in 1080p60 at the click of a button. There’s zero video lag if you use their software’s preview function as your display, and it is also a perfect pass-through of the incoming resolution.
