I found that during the campaign the bodies dissappeared. But during the historical battle they did not. I also find dissappearing bodies an annoyance. I tinkered with all the settings and the only thing that I had set at high was unit detail. The rest varied from medium to high. Grass and shadows off. Historical battle bodies did not dissappear but I didn't try the campaign again with these settings. I wondered if the bodies in the campaign would dissappear irreguardless of settings for performance reasons. I don't really know, I didn't try the campaign again with the settings adjusted. The bodies just add so much, I don't know, atmosphere, when a battle is taking place and over!
