not sure. allot. AI isn't really that difficult when they don't need to do anything.
wf does tons of checks down the list for AI, to just pile in monsters that don't really do anything, probably whatever max entities is.
jalisko had about 200 monsters running around a q3 level. they didn't do much, sorta like serious sam AI tho just to prove that you could shove in a few dozen things that were just scripted and it wouldn't make a difference performance wise.
