Lagging on large maps

[Katorok]

So a friend and I were playing together, and it was a large, towards the end of the game, things got laggy for him.. Really laggy, every turn it was a 30second lag, and if anyone civ talked to him it would also lag.. Other than the beginning of every turn, or when someone spoke to him, it was fine.

Is there anyway to reduce this lag? His computer is fairly decent, can run a good deal of modern games on medium-high..

I myself lag a bit when playing with 18 civs on a huge map, anyway to reduce that?

Well i also have a decent pc, but i still lag when playing on huge maps. Mostly in the end game when there are lots of cities and units on the screen at once. I can´t of any other way to reduce this lag than to set graphics level down or change the resolution. Of you are considering investing in a new pc. Pick one that has a powerful processor, and a decent amount of RAM. Of course you need a decent graphic card too, but processor speed is more important when it comes to Civ.

please post your dxdiag results file.
also the game is patched to date, correct?
depending on your machine some lag reduction may be possible - or not
