It seems NVIDIA has a new GameWorks library for Volta GPUs, this library is exclusive to NVIDIA, it's for ray tracing certain effects such as AO, reflections, and area shadows. The library is co developed with Microsoft to be integrated with DirectX Raytracing API and is being adopted by these engines and developers: Unreal, Unity, Frostbite, 4A (Metro Exodus), and Remedy (Northlight engine?).
