Last month Epic Games gave us an early taste of what we can expect from the next generation of gaming with “Lumen in the Land of Nanite,” a stunning real-time Unreal Engine 5 demo running on PlayStation 5 hardware. The demo looked incredible, downright photorealistic at times, but according to Epic, the demo wasn’t the hardware-busting beast you might expect. In fact, according to Epic’s VP of engineering Nick Penwarden, the demo didn’t require significatntly more GPU power than Fortnite...

I can say that the GPU time spent rendering geometry in our UE5 demo is similar to the geometry rendering budget for Fortnite running at 60fps on consoles.
