In 2013, Epic Games teased the capabilities of Unreal Engine 4 with the Infiltrator demo. It looked incredible at the time, and you can still read awestruck comments from 7 years ago on YouTube. Of course, today the sci-fi vignette just looks so-so. It’s astonishing how quickly unbelievable tech becomes everyday.

Well, here we go again: Unreal Engine 5 is releasing next year, and Epic Games has a new PlayStation 5 tech demo called Lumen in the Land of Nanite to show it off (embedded above). Like that Infiltrator demo did back in 2013, it looks just a bit unreasonable, with dynamically-lit, photorealistic caves and then, at the end, an entire crumbling city with no less detail.
