No they don't. Also optix isn't a renderer, it just traces rays and runs shaders on the ray hits on nvidia cards. Memory limitations and immature renderers hinder gpu rendering. The makers of gpu renderers want you to think it's what most companies use, but it is not.

Also Hollywood is a city and most computer animation is not done there. The big movie studios aren't even in Hollywood except for paramount.

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.
