long response time after issuing a command

[philondra]

This is my first post on this forum, but I am a long time lurker.

I have installed Civ IV and find that I have very few issues except for one: In single player, there is about a 1-2 second response time between issuing a command and the game carrying it out.I do not think that this is a graphical issue, as I get between 20-30 FPS for the majority of the game (things go down a bit when the map is revealed, but it is still around 15-20 FPS. There is no issue with map scrolling or the like, only this "command lag" problem. Has anyoned experience a similar problem and have any suggestions for fixing it? Or is this just something that I have to learn to deal with (It makes a game take a LOT longer when it takes 2 seconds to move a worker and another 2 to build a farm -- let alone assault Tokyo!)

Here are my specs for reference -- I am well above recommended:

Windows XP
ATI Radeon 9800 XT, 256 MB RAM
Pentium 4, 2.60 GHz
2 GB RAM

For reference, I updated sound and video card drivers, installed SP2, defragmented my hard drive, made sure that I had the latest direct X, and fiddled around with graphics settings (no change whatsoever)

Any ideas?

Same boat...more or less. It runs, but it's very slow. In the later game it starts to crash frequently. Running a 5200 FX though.

I have a fairly newer high end system.
Athlon 64 3500+
1 GB Corsair XMS
GeForce 6800GT
2x 34GB Raptors in RAID array

I don't have too many problems when playing on standard size maps, with an average number of AI. But the game is virtually unplayable on Huge maps with a large number of AI CIVs.
I think the slowdowns are related to map size, number of civs or some combination of this. Try reducing number of AI.
Can anyone run this game with Huge map and large number of AI?
