CPU utilization?

[lch]

Let me add something which I think is fishy: Whenever a fight is done in a province where it is winter (white ground), the animations take about twice as much time as normal (green ground or whatever). It doesn't have to be raining/snowing, which causes the battle replay to run slower, too, of course, it just has to be cold with the ground covered in white, doesn't even have to contain a lot of trees. Since that white ground is nothing else than green grass (from a programming perspective) to me, I wonder why it's slower.
