Try 16-bit color depth -- plays faster

Yes, the game so far looks the same, uses less Virtual Memory and try it, it may work for you also!

How? I don't see any options for changing this.

There is a Major Memory issue in Civ IV. A fix has been produced that really does work. The thread is sprinting towards 32,000 hits at the time of this post - all in 4 Days!

Its not a dubious amateur hack. If you get CTDs - slow down - reboots - massive save files etc - go now to this thread, its put Firaxis to shame

Er, okay, ignoring the off-topic remark:

I've seen a few people suggest 16-bit color depth, but no one has said how. The graphics options in Civ only extend to resolution, not bit depth.

Right-click anywhere on your desktop, select Properties. Go to the Settings tab, change Color Quality to 16-bit. This will affect all applications you run on your computer.
