The notes for Unreal Engine 4.22 have recently been released, and things are starting to look a lot brighter for Nvidia's RTX series of graphics cards.

A list of supported features include:

  • Real-Time Ray Tracing and Path Tracing (Early Access)
  • Added ray tracing low level support.
  • Implemented a low level layer on top of UE DirectX 12 that provides support for DXR and allows creating and using ray tracing shaders (ray generation shaders, hit shaders, etc) to add ray tracing effects.
  • Added high-level ray tracing features
  • Rect area lights
  • Soft shadows
  • Reflections
  • Reflected shadows
  • Ambient occlusion
  • RTGI (ray traced global illumination)
  • Translucency
  • Clearcoat
  • IBL
  • Sky
  • Geometry types
  • Triangle meshes
  • Static
  • Skeletal (Morph targets & Skin cache)
  • Niagara particles support
  • Texture LOD
  • Denoiser
  • Shadows, Reflections, AO
  • Path Tracert
  • Unbiased, full GI path tracer for making ground truth reference renders inside UE4

Along with improved DLSS - this hopefully indicates that 2019 will end up with more than just two games supporting Ray Tracing.
