CPU utilization?

I expect it has to do with transparancies instead. That and the scrolling. It may be interesting to set GUI transparency to 100% and see where that leads

The answer is it doesn't make a difference. Poo.

I'm not sure why the 'AI Thinking' takes so long for large maps when the AI has lots of commanders/mages even on powerful computers.
Let me say I don't mind the 2hour or longer waiting process, but examining the processes in the background I'd suggest offloading some of the turn processing work onto the RAM. The RAM hardly gets touched in comparison.

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.
