As promised earlier this week, AMD released the full Hangar 21 Technology Demo video that's meant to be a showcase for the brand new RDNA 2-based Radeon RX 6000 GPUs.

Most of them have been commonplace in games for some time already, such as dynamic area lights, volumetric lights, real-time global illumination, physically based material and shading, volumetric fog, god rays, and depth of field.
