General System Issues

Optimizing Gameplay on Slower Computers

If the game is running slowly on your machine, try turning the detail
levels for all graphical options down to the minimum, and then
adjusting them one by one until you achieve an acceptable balance
between visual quality and game performance. You can modify the
graphical options by pressing [Ctrl 0] or via the Options selection in
the main menu.


Video Issues

General Video Troubleshooting.

Outdated or incorrect video drivers are the cause of the majority of
video issues. Before contacting support, ensure you have the latest
production (release) drivers for your video card.

* ATI Technologies
* Intel
* Matrox
* NVIDIA
* S3 Graphics
* SiS

I get a message that says "Unable to initialize DirectX" when I try to
launch the game.

This issue is typically seen on machines that have an ATI Graphics
Card. Please follow this link for the complete walkthrough on how to
solve this problem: http://www.2kgames.com/civ4/support.htm

Sound issues

If you are experiencing sound problems, including volume issues,
missing audio channels (i.e., no sound comes through your center
speaker channel), crashes, or any other audio issues, we recommend
switching your sound driver to the default MILES Fast 2D Driver.
