Epic Games have announced that Fortnite Chapter 4, which went live today, is using Unreal Engine 5.1. This means it has access to the new features like Nanite, Lumen and Temporal Super Resolution. Fortnite is the first game to make use of the new Unreal Engine 5.1, which is also developed by Epic Games.
In Fortnite, the Nanite feature makes it possible to create very complex geometric objects, without any loss of performance. This results in much denser forests with more detailed trees or buildings that consist of millions of polygons, which are destructible in much finer increments.
Temporal Super Resolution is a method of graphical upscaling, which means a graphics card doesn’t have to render the scene in the native resolution. The upscaling is done on the fly and is hardly noticable by the human eye. This also results in a huge performance boost, but you need a powerful graphics card to handle the calculations.
There’s a detailed blogpost here, which explains a lot of the advantages of the before mentioned techniques. Check out the trailer for Fortnite Chapter 4 Season 1 below.
