Maybe an AI thread got stuck? Though usually when that happens, it results in a crash instead of a delay.

Just tried a new game, again. Huge map (as before), three opponents, randomized terrain. Same problem.

Now before someone points out, I know the game is going to take longer to update on a huge map than on smaller ones. My point in turn is that it's gone from 3-5 seconds to being unplayably long. At this point, I'll just have to wait for the next game update before getting into LH, again. At least I've still got FE installed.

Thanks for the quick response, Derek. I'll try turning down anti-aliasing, though as the issue only occurs in turn updates, rather than map scrolling, I have to wonder whether it's something else.

I'll do a reboot, clean out any registry issues I might have right now (Windows just installed some updates), and see if that helps. Didn't *see* anything stuck in the registry, but you never know.
