There is presentation after presentation by pixar that shows what you just wrote is crap. 3d rendering is done on Linux super computes and Linux workstations and macos systems at Pixar. Yes that at a conference where the presenter does not have to use Linux. But here is the pixar person using gnome desktop and Linux todo his presentation.
Please note I said supercomputer and Linux workstations and macos systems. How is this possible it called render farm software. Render farm software means that you can make a computer screen saver that when active join processing resources of the workstation to the supercomputer cluster and yes disconnect from cluster as soon as a person starts using the machine.
Do note what I said you watch a video walkthough of pixar you will see 2/3 linux 1/3 macos. But its known that pixar uses some windows software. Of course in a walk though the place is normally without staff sitting at their machines so everything is joined to the render farm so of course all computers are in the mode to join the render farm. Windows in pixar if on bare metal will be dual boot to Linux but windows in VM also happens.
Pixar there is no such thing as a pure windows machine. Linux workstations are at Pixar and are in fact used as part of the used as part of the rendering solution. MacOS and Linux are your 3d and 2d rendering heavy lift machines. The fact windows does not make a good 3d rendering heavy lift does make usage at pixar discouraged. 0.001% extra performance in some cases can be talking a week difference in rendering time.
Pixar usage of Linux workstations is forced by the work they do. Windows network stack performance issues and connections limits is a serous issue when you want to connect a windows machine to a render farm and keep good performance. So being a effective 3d rendering node in a 3d rendering cluster is something desktop versions of windows is no good at.
sophisticles like it or not the claim that 3d rendering at pixar is done on Linux Workstations is true. But 3d rendering also done on MacOS and the Linux Supercomputer as well. This all about getting the most computing power you can for 3d rendering to reduce the number of days rendering takes and part of that is absorbing your workstations into your 3d processing pipeline in the highest performance way.
