SGI's "Visual Workstation" series with Cobalt graphics subsystem

• had 1 GB or 2 GB maximum memory, depending on model
• the graphics subsystem, Cobalt, supported "approximately 80% of total system memory available for textures"
• reportedly did not support Clipmapping or Performer
• notes from Doug Cox of Paradigm/VisKit, using it for texture paging in a dual-CPU machine:
  • "Cobalt Gfx - Very impressive, no OpenGL driver problems so far.  ~30fps making it the fastest in the group.  However, there is noticeable pausing/skipping as textures are loaded in the 2nd thread and we're moving around in the app. We cannot seem to explain this. We took them out of the scene (to test if it was the glBindTexture) call, but it appears to be the act of file IO and converting the image to a vk texture from a PNG. (and yes the thread does appear to be running on the 2nd processor) This makes the SGI fairly useless to demo our app on."
• it appears that SGI cancelled the product
