This uses hardware-accelerated raytracing on NVIDIA RTX graphics cards. It is still currently experimental. Most features are supported, but a few are still missing like baking, branched path tracing and using CPU memory. https://wiki.blender.org/wiki/Reference/Release_Notes/2.81/Cycles#NVIDIA_RTX For building with Optix support, the Optix SDK must be installed. See here for build instructions: https://wiki.blender.org/wiki/Building_Blender/CUDA Differential Revision: https://developer.blender.org/D5363
