Octane is exactly the type of thing I'm talking about. This is not what film is rendered with. It is mostly combinations of PRman, Arnold or proprietary renderers, all software. I don't know where you are getting "nvidia hate", studios that use linux usually use nvidia, mostly because of the drivers. None of this changes that optix is not a renderer.
