Octane Render

Octane Render is an unbiased rendering application with real-time capability developed by graphics software company OTOY Inc. Octane render was the first commercially available unbiased raytracer that fully utilized the GPU, giving it a significant speed advantage; this allows users to more easily modify scenes in real time.
Octane Render runs on Nvidia's CUDA technology when using Nvidia GPU video cards; Octane X for macOS Big Sur runs on Metal on AMD, Intel Skylake and Apple M1 graphics cards.
