Unreal Engine is an open and advanced real-time 3D creation platform. Continuously evolving beyond its original purpose as a state-of-the-art game engine, it gives creators across industries the freedom and control to deliver cutting-edge content, interactive experiences, and immersive virtual worlds.
NVIDIA and Unreal Engine 5
NVIDIA supports Unreal Engine 5 with key RTX technologies. Developers of all levels can get started and harness the power by combining NVIDIA technologies and Unreal Engine to propel games and experiences to the next level.
NVIDIA DLSS is a deep learning neural network that boosts frame rates and generates sharp images.

NVIDIA Unreal Engine Custom Branches
NVIDIA has made it easy for game developers to add leading-edge technologies to their UE games by providing custom UE branches for NVIDIA technologies on GitHub. These branches shorten the development cycle and bring stunning, rich detail to your games.
NVIDIA RTX Branches of Unreal Engine
The NVIDIA RTX branch of Unreal Engine (NvRTX) includes enhancements to the DirectX Raytracing (DXR) first enabled in UE4.26. It’s ideal for developers adding ray tracing to their games or applications. Get started with RTXDI available through the NvRTX branch.
Get started with NvRTX
NVIDIA RTX Caustics Branch
The NVIDIA RTX caustics branch is an experimental version of our popular NVIDIA RTX branch, which introduces an improved hybrid-translucency mode, multi-bounce refraction optimization, mesh caustics, and water caustics.
Get started with caustics, part 1 Get started with caustics, part 2 Download the branch on GitHub
NVIDIA Plugins for Unreal Engine
NVIDIA plug-ins for Unreal Engine offer options for powerful, fast, and scalable solutions capable of computing infinite multi-bounce indirect lighting without bake times, expensive per-frame costs, and light leaks in a ray-traced setting. The plug-ins can also increase frame rates by rendering fewer pixels and construct sharper, higher-resolution images by using AI. They provide an ideal starting point for bringing the benefits of ray tracing to existing tools, knowledge, and capabilities. For a more detailed breakdown of ray tracing in Unreal Engine click here.
Deep Learning Super Sampling (DLSS)
NVIDIA DLSS is a deep learning neural network that boosts frame rates and generates beautiful, sharp images for your games. It provides the performance headroom to maximize ray-tracing settings and increase output resolution. DLSS is powered by dedicated AI processors on RTX GPUs called Tensor Cores.
DLSS is available for Unreal Engine 4 (UE4) as a plug-in, compatible with UE4.26, UE4.27, and UE5.
