NVIDIA UE4 CUSTOM BRANCHES

NVIDIA has made it easy for game developers to add leading-edge technologies to their Unreal Engine 4 (UE4) games by providing custom UE4 branches for NVIDIA technologies on GitHub. Having custom UE4 branches on GitHub shortens the development cycle, and helps make games look more stunning.

RTX Branch

The NVIDIA RTX Branch includes enhancements to the DXR support found in UE 4.27. It is ideal for developers adding ray tracing to their games or applications.

DLSS AVAILABLE THROUGH UE5 AND UE4

NVIDIA DLSS is a new and improved deep learning neural network that boosts frame rates and generates beautiful, sharp images for your games. It gives you 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 now available for the first time for UE4 as a plugin, compatible with UE4.26, UE 4.27, and UE5
