Display PostScript did come out shortly afterwards, with entirely 
different extensions for interactive use.

Also X11 came out and was almost unanimously adopted as the standard GUI 
engine by the Unix community. Including Sun. It ran a hybrid X11-NeWS 
server for a while, before giving up on NeWS altogether. (NeWS fans were 
not happy.)

It wasn’t just a performance issue, it would also have been the trickiness 
of synchronizing concurrent processes in the CPU versus the GUI server 
while avoiding problems like deadlocks etc.

Mulithreading was being used for just about everything in the 1990s, until 
it was realized that multithreaded GUIs were more trouble than they were 
worth.
