NVIDIA RTX Branch of Unreal Engine

NVIDIA has made it easy for game developers to add leading-edge technologies to their Unreal Engine games by providing developers with custom branches for NVIDIA technologies on GitHub. The NVIDIA RTX™ Branches of Unreal Engine (NvRTX), are optimized and contain the latest developments in the world of ray tracing and neural graphics.

For more tips and tricks regarding raytracing, please take a look at our Unreal Engine 5.4 Raytracing Guide

The ramen shop scene above, created by the NVIDIA Lightspeed Studios art team, runs in the NVIDIA RTX Branch of Unreal Engine 5 (NvRTX 5.1). The scene is rendered using RTX Direct Illumination (RTXDI) for ray-traced lighting and shadows alongside NVIDIA DLSS 3 for maximum performance.

Featured RTX Technologies

RTX Global Illumination

RTXGI provides scalable solutions to compute infinite multi-bounce lighting and soft-shadow occlusions without bake times, light leaks, or expensive per-frame costs (NvRTX 5.0 & 4.27 ONLY).
