Surely you don't have to look after 50 provinces a turn. Most provinces just sit there looking after themselves, especially with the autotaxation turned on. Generally the only ones that require checking are ones with fortifications, where you build troops, ones where there's military action, and occasionally you might want to check them out if there's been some form of event. Maybe every once in a while you have to do a big whip-round with magic site scrying spells...

In SP I do turns quickly because I don't care about mistakes that much. MP turns take me rather longer, most of it is sorting out army commands.
