In fact, remarkably, the resolution differential is now a 2x improvement in favour of Xbox One X, a measurement at odds with the raw improvement in rendering power the hardware specs suggest - but confirmed in gameplay nonetheless. It's a 10 per cent drop in pixels for the new machine, but it still compares well to the 2560x1440 on PS4 Pro in this spot. Here, we're faced with our first taxing area at the gates, filled with enemies, physics-based objects and geometry, forcing Xbox One X to makes a rare slip below 4K - down to 3648x2052. Things start to change as we head towards New Tristram's gates, and the resolution adapts on both sides. In like-for-like situations, that's a 77 per cent increase in resolution in favour of the Microsoft console, before even touching a button. To put some hard figures to this, overlooking New Tristram right at the start with a new character, sees Xbox One X delivering 3840x2160 - the full 4K experience - while PS4 Pro kicks off at 2880x1620. But in practice, Sony's machine tends to run at lower numbers in the town itself - while Xbox One X hits 4K almost perfectly throughout. In PS4 Pro's case, a full 3840x2160 is only hit around interior areas, like the bar at New Tristram, or small dungeons. What's clear is that as good an upgrade as the PS4 Pro version is, Xbox One X goes one better, with a much closer lock on the target 4K resolution. But the question is, just how close are the two versions? And to what extent does Xbox One X's higher spec translate into a closer lock to a native 4K?

And just like the PS4 Pro version, Xbox One X benefits from a smattering of visual enhancements too. The same principles are in place: the game targets a native 2160p presentation, but utilises a dynamic scaler to lock to the target 60 frames per second, adjusting the pixel count on the fly to ensure consistent performance.

Cited as an example of ultra HD gaming on Microsoft's list of Xbox One X enhanced titles, Diablo 3 is an evolution of Blizzard's good work on the PlayStation 4 Pro version of the game.
