RAM is still under 2gig, so very low. I don't know about final settings yet. The bigger and more detailed I make it, the more details I have to put in the houses and fields as well. And it's a heck of a job already. Especially making all the quite specific houses. So actually I hope to keep it a bit hazy by all the smoke fires, and a low sun. To obscure less than high quality stuff, and make it dramatic and 'Medieval'.
'Crowding' the streets with stuff like boxes, tables, gates, people, dogs, carts, fences, crates, sacks, cattle is what I dread most. I will probably have to paint some of that in by hand where necessary. That would be easier than putting it all in as objects (whether single or as populations).
