NVIDIA also cares about Hollywood and CAD/CAM shops.
I learnt three times that AMD isn't necessarily better in Linux as advertised, now I don't care any longer.
A lot of Hollywood studios use renderers that jump straight to CUDA as their backend. Cycles is a popular one, as well as Renderman and Octane.
I'm not aware of any commercial CAD/CAM software running Linux that Nvidia would have a money interest in supporting. Which current CAD/CAM is running on Linux with graphics? The closest I'm aware of it FEA packages allowing remote calculation on Linux machines while the GUI runs on Windows. Is that what you're referring to?
