It needs a plugin. It works okay for single pages, but if you
make the mistake of opening a 200-page document with it, it will try to
render the whole thing in one go and you'll end up terminating it.

IOW, remember to set the file association for .ps files back to GSView
(etc) after installing the plugin.
