I first took a look at the results in Days Gone, the open world survival horror title from Sony Bend. I observed the pixel structure on a 65-inch Sony 4K display from just two feet away, and then I moved closer. It looked good, seriously good. There is a slight softness compared to the pin-sharp precision of a native 4K presentation, but even close-up, the effect works well - in a living room environment, it should work just fine. In common with the other titles using this technique, the demo code we saw can switch in real-time between 1080p and '4K' at the press of a button, with HDR on and off also selectable.There is a clear, unambiguous night and day difference between 1080p and the 4K mode, which is clearly resolving more than the basic 2x increase in pixel throughput being generated at the base level. In fact, the detail increase is almost revelatory - and that applies equally to both Days Gone and Horizon Zero Dawn.

But the key takeaway is this - while the PlayStation 4 Pro GPU lacks the horsepower to render out challenging content at native 4K, the presentation we've seen on a number of titles clearly shows a worthwhile, highly desirable increase in fidelity over 1080p - one that does put a 4K screen to good use. Switching between full HD and checkerboard 4K, the increase in detail is simply stunning.

At the PlayStation Meeting, Crystal Dynamics were only showing the 4K mode. We've played a fair amount of this title recently, on both the Titan X Pascal and dual GTX 1080 SLI. It is, quite frankly, one of the finest 4K gaming experiences available. PS4 Pro is compromised a touch - it looks a little softer, and quality presets are pared back - but the core of the experience, the 'upgrade factor' over 1080p if you like, is there. This was by far and away the best third party 4K title we saw at the PlayStation Meeting.
