Well I'm running the game on a XP 32bit machine with Dual Core on 3Ghz, 2GB DDR3 and a 4870 512 MB. For me it's unplayable. All game modes are really really slow. I tried Kingdom wars, but during a fight the game lags and stutters every 5 seconds. I cannot command my troops well. It takes a few seconds before the troops react on my clicking. Even when I'm not directly looking at the troops the game stutters. I remember Total War to calculate only the troops on screen, (where you look) but DoF certainly does not. It feels like the game is calculating all troops on the map. So always using tons of pc power. Strange. Shouldn't you optimize that?
Anyway, I have all possible visuals turned off and to the lowest. What going wrong? Running my native resolution 1440x900 or a lower 1024x768 does not change a thing either. Changing resolution is a haggle anyway. Ingame it does not work....
The game feels great . Hope that many things will get optimized soon and that 'medievil' font is terrible. Not really black and not sharp at all. Feel like an old 90's game :P
