NVIDIA OptiX is now supported with hybrid rendering, so all GPUs and CPUs available in a system can be used, ensuring maximum system resource utilisation. Baking is also now available when OptiX is active, enabling artists to continue using the fastest rendering software.
Finally, NVIDIA GPUs can automatically contribute to help render sections of models being rendered by the CPU once the GPU has completed its tasks, a process called tile stealing, which further improves hybrid rendering performance.
In short, rendering with Blender, no matter the task, just got better.
