The technical specifications on the PS5 and Xbox Series X are relatively comparable, but Epic Games chose to only show Unreal Engine 5 on the former during its demo this week. However, according to studio head Tim Sweeney, this decision does not mean the Xbox Series X can't handle the impressive visual effects.

Writing on Twitter amid fan speculation, Sweeney shared that the technology powering the Unreal Engine 5 demo that Epic Games prepared will be fully supported on both systems. It chose to work with Sony to produce the demo because of "years of discussions" between the two companies.

The Lumen technology refers to a new illumination system put in place for Unreal Engine 5 that makes it much easier for environments to showcase "natural" night from various sources. Nanite is a system for creating and importing extremely detailed geometry through billions of tiny triangles.
