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.

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)
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).

(RTXDI)
RTXDI lets artists add unlimited shadow-casting, dynamic lights to game environments in real time without worrying about performance or resource constraints.

Deep Learning Super Sampling
(DLSS)
DLSS leverages the power of a deep learning neural network to boost frame rates and generate beautiful, detailed images for your games.
