Epic Games presents Chapter 4 of Battle Royale Fortnite. With this, the game switches to Unreal Engine 5.1, which brings Fortnite support for graphic features like Nanite, Lumen, and Temporal Super Resolution, among others. Fortnite Chapter 4 is available now.
Epic Games announces the transition to Unreal Engine 5.1 in a blog post. This includes support for the battleroyale game’s Nanite rendering system introduced in Unreal Engine 5. This “virtual geometry” system provides the ability to render objects in millions of polygons without negatively impacting performance. For example, according to Epic Games, individual trees gain around 300,000 polygons thanks to Nanite. Every building in the game is made up of “millions of polygons” thanks to Nanite.
Fortnite is also getting support for Lumen, which is a type of software ray tracing. In Fortnite, this technique is also used to reflect on glitter and water global illumination for ambient lighting at a frame rate of 60 fps. In conjunction with that, Epic Games Virtual shadow maps for the game, allowing for more realistic shadows. The game also gets Temporal Super Resolution, which is a temporary upgrade technology like Nvidia DLSS and AMD FSR 2.0.
Gamers can use the Nanite renderer on computers that have at least an Nvidia Maxwell or AMD GCN GPU or later. However, Epic Games recommends at least an Nvidia GeForce RTX 2080 or AMD Radeon RX 5700. Nanite only works with DirectX 12. On PlayStation 5 and Xbox Series consoles, Nanite, Lumen, and Temporal Super Resolution only work when 120fps mode is turned off, Epic says.
Epic Games introduced these new features in Unreal Engine 5, which was officially released earlier this year. earlier this month Unreal Engine 5.1 follows, an update that enables better support for Nanite and Lumen at 60fps on consoles, among other things. Fortnite is one of the first games to switch to this version of the engine. Tweakers was published earlier this year Interview with Epic Gameswhere Unreal Engine 5 and its new features are explained by Nick Penwarden and Arjan Brussee.
