CPU maxes out

[Briasaurus Rex]

So, Beyond the Sword causes the CPU to max out in a strange way. Civ itself never seems to use much more than 30 - 40% tops, but causes other process to use more cycles than they usually do. Sometimes it will be focused on a few processes, other times its real spread out with lots of processes using 2 - 5%. By contrast, memory usage never gets above 50 - 60%.

Here's my vitals:
Windows 7 32bit
2 gigs of RAM
2 GHz Intel Core2
Nvidia GeForce 7300 Go 128mb

I was reading elsewhere that Huge maps were causing problems, but if I read correctly, it was more a memory issue than a CPU issue.

Welcome to CFC!

Civ 4 is not multi-core aware so with a dual core Civ will not use more than 50% of your processor. W7 spreads it across the cores, but on older OSs you will see one core at 100% and another at 0%. I've not seen reports of other processes using more than normal though.

Yeah, I've never seen anything like it either. Pretty weird, right?

I'll try to get a screen grab and post it here. Could be a process explorer error, I suppose... but that doesn't seem too likely.
