Overview

Scalability Settings

The Scalability settings allow you to adjust the quality of various features in order to maintain the best performance for your game on different platforms and hardware. (find the default settings in "BaseScalability.ini")

Anti-Aliasing Method:

0: off (no anti-aliasing) 1: Fast Approximate Anti-Aliasing (FXAA) 2: Temporal Anti-Aliasing (TAA) 3: Multisample Anti-Aliasing (MSAA, Only available on the desktop forward renderer) 4: Temporal Super-Resolution (TSR, Default) 5: Subpixel Morphological Anti-Aliasing (SMAA)

If you disable Virtual Shadows and Ray Traced Shadows, the engine falls back to Cascade Shadow Maps.

“Lit” is the default view mode. If you don’t need to use any other mode, press “Lit” to return to the default view.

For the buffer mode, press “Disable” to stop showing any buffer visualizations.

Path Tracing

Epic documentation:

Path Tracer in Unreal Engine | Unreal Engine 5.7 Documentation | Epic Developer CommunityEpic Games Developer

The Fallback Mesh is used for Nanite-enabled meshes by default. Lower the Fallback Relative Error parameter in the Static Mesh Editor to use more of the source mesh's triangles. (Experimental) Initial support for native path tracing of Nanite meshes is enabled when setting the console variable r.RayTracing.Nanite.Mode 1. This preserves all detail while using significantly less GPU memory than zero-error fallback meshes.
