I'm not clear on how monitor frame-rate affects map size?
It is just an example, which is practically irrelevent, in fact it is a bad example quoted. Because Civ4 is not an action game which requires huge number of frames per cycle. For Civ4, it is not the rate of display that is matter, but the amount of details...
Still whatever title you can give to the display engine, a 3D, 4D or what so ever, if Civ4 programmer make it capable of handling huge map, they should have no problem with smaller one ... this is simple understanding/logic and can't be distorted with technical hardware terms or an irrelevent example.
