[PvK]

It is a pain, but I haven't seen quite that much delay in opening windows with my 1000+ ship game on a slower machine, but then I didn't have 1600, nor 800 bases.

Mainly I would avoid using the ships/units window, which I don't use very much anyway.

And of course, most ships were in fairly large fleets.

Still, it would take me over an hour to do a turn properly.
