Chapter 4 of the battle royale game Fortnite has arrived, and in conjunction with the launch of the new chapter, Fortnite will now use the latest and most updated features of Unreal Engine 5, hot on the heels of the Unreal Engine 5.1 update.

Unreal Engine 5 ushers in a new generation of visual fidelity, bringing an unprecedented level of detail to game worlds like Battle Royale Island. Next-gen Unreal Engine 5 features like Nanite, Lumen, virtual shadow maps, and Fortnite’s hyper-resolution timed battle royale are now available on PlayStation 5, Xbox Series X|S, PC, and cloud play.

Features NANITE, LUMEN, standard shadow maps, and super temporal resolution

NANITE resource

Nanite provides high-precision geometry. Specifically, buildings are rendered from millions of polygons in real time, and every brick, tile, and wall structure is modeled. With HD landscape scenes as well. Individual trees have around 300,000 polygons, and every stone, rosette, and blade of grass is also modeled.

LUMEN Resource

Lumen reflections provide high-quality ray-traced reflections on glossy materials and water. Lumen also renders global illumination in real time at 60 frames per second. You’ll see beautiful interiors with diffuse lighting, as well as characters interacting with the lighting in their environment. (For example, a red brushstroke might reflect red light onto their uniform.) Additionally, clothing with emissive properties (known as shiny) diffuses light onto nearby objects and surfaces.

Virtual Shadow Maps

Virtual shadow maps allow for high-resolution shading. Every brick, leaf, and detail you model will cast a shadow, and self-shadowing will appear with incredible accuracy. This means that things like hats and other small details on characters will also cast a shadow.

Temporary Super Resolution (TSR)

Temporary Ultra Resolution is an improvement over Fortnite's Temporary Blur, allowing for higher resolution visuals at a higher frame rate.

Changes to video settings on your computer

With the arrival of these UE5 engine features in Fortnite, the Fortnite video settings on PC have changed. You will need to do the following.. Now go to the “Display” section of the video settings

Display style setting

• Navigate from the “Advanced Charts” section to the “View” section.
• DirectX 12 is now the default display mode on computers with select Super GPUs.
• The “Performance” rendering mode is no longer available in the beta and is now called “Performance – Lower Graphics Resolution”.

Configure “vertical sync”

• Navigate from the “Advanced Charts” section to the “View” section.
• The “Graphics” section of the video settings

Motion Blur Setting

• Navigate from the “Advanced Charts” section to the “Charts” section.
• It is now disabled by default.
• Selecting quality automatically in the Graphics Quality section will not enable this setting, but it may disable it on a computer with fewer resources.

The “Graphics Quality” section of Fortnite’s video settings

The “temporary high resolution” setting includes the following options.

• Recommended (default): Sets the 3D resolution based on the best resolution available for your display.
• Performance prioritizes frame rate over final image quality by rendering at a lower resolution.
• Balanced: Balances image quality and performance.
• Quality: Prioritizes final image quality over performance when rendering at a lower resolution.
• Original: Allows you to render frames at their original resolution at the cost of performance.
• Custom: Allows you to customize 3D accuracy via a tape measure.

Setting Default Nanite Geometry

• Only available if you select Display Mode for DirectX 12.
• Nanite is enabled if the default Nanite architecture is enabled.
• The “Shadows” setting name will change to “Default Shadows” if Nanite is enabled.
• Enabled by default when the Quality Presets setting is set to High or Epic.
• Please note that this setting cannot be changed during a match.

Define “general lighting”

• Enables global Lumen illumination when selected to High or Epic.
• This setting only has two options if Nanite is disabled: Disable and Surround Match. (Ambient Match = lower quality ambient lighting with darker corners.)
• When Nanite is enabled, two more options will be added: High Lumen and Epic Lumen.
• Please note that this setting cannot be changed during a match.

Defining “Reflections”

• Enables lumen reflections when set to High or Epic.
• This setting only has two options if Nanite is disabled: Disabled and Screen Space. (Screen Area = calculates reflections based on what is currently on the screen.)
• When Nanite is enabled, two more options will be added: High Lumen and Epic Lumen.

Device Ray Tracing Configuration

• Device ray tracing provides the ability for Lumen global lighting and Lumen reflections to use cross-device ray tracing processing. (The “Device ray tracing” setting in the “Graphics Quality” section overrides the “Ray tracing” section.)
• Disabled by default.
• To enable ray tracing for your device:
• Nanite needs to be activated. (In other words, the “Nanite Virtual Architecture” needs to be enabled.)
• Both “General Lighting” and “Reflections” need to be set to High Lumen or Epic Lumen.
• Enabling or disabling this setting requires a game restart to take effect.

Automatic quality setting

• The Auto quality setting sets most graphics quality settings to Low, Medium, High, or Epic, and specifies options for the General Lighting and Reflections settings.
• Sets the Super Resolution noise reduction setting to the TSR Low, TSR Medium, TSR High, or TSR Epic options, and sets the Temporary Super Resolution setting to Recommended.

Minimum computer specifications required to run NANITE

IF I PLAY FORTNITE ON PLAYSTATION 5 OR XBOX SERIES X|S I WILL NEED TO DO SOMETHING THAT ENABLES NANITE, LUMEN, Default Shadow Maps, and Temporary Ultra Resolution. To make Fortnite’s Nanite, Lumen, Default Shadow Maps, and Temporary Ultra Resolution available on your PlayStation 5 or Xbox Series X|S device, you need to make sure that the “120 fps mode” setting in the “Graphics” section of the video settings is disabled.
