@wolf480pl @rygorous I don't know how many used SGI hardware. There were still a fair number of dedicated military graphics systems from various companies, some of whom later moved into the consumer space, e.g. Martin Marietta. I used to know more about this space because 3Dlabs bought a ton of their patents, and one of my jobs was spotting which other companies were violating "our" patents. But time has not been kind to my memory.
