Basically, an acquaintance of mine is having increasingly large battles in his campaign. Something like around 6000 men. In a custom battle this is fine and it runs acceptably.
However in the campaign he is getting the message saying that his PCs specs arent good enough and so not all soldiers make it to the battle. It seems he has a cut off at around 4000 soldiers no matter how much he turns down the graphical niceness.

So the question is, how do you get around this? Is there a way to stop the game deciding what battles your PC can handle?

Im sure someone said something about this for either Med 2 or Rome.
