Alan Wake 2 was released last October with path tracing and DLSS Ray Reconstruction, receiving a lot of attention for the visual experience it offers. This session explains all aspects of the path tracer including acceleration structure management with large amounts of dynamic content, representation and accessing of material data, light sampling techniques and image upscaling and denoising methods. All key technologies are covered including using of the opacity micromaps (OMM) with alpha tested assets such as vegetation and hair, use of the shader execution reordering (SER) in the path tracing shader, how the DLSS Ray Reconstruction is used to produce the final image, and how smooth frame rates are achieved through the DLSS Frame Generation.


Using path tracing and NVIDIA technologies such as DLSS Ray Reconstruction in your game can be convenient and you can achieve stellar results and get good value for your investment.
