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.
