Here's what I was having:
Every second, on a clear cycle, the display would hitch for a split second. This affected the intro movie, the main menu and actual gameplay. It manifested itself in the intro movie by dropping a few frames every second and in the main menu by making the mouse pointer move unsmoothly (again, hitching every second). The same problems made the game, itself, rather unplayable.
Here's what solved it:
I double-clicked on the _Civ4Config shortcut in the game folder (which opened up the CivilizationIV.ini file stored in the user profile), found the SyncInput line in the middle of the file and changed its value from 0 to 1. Problem solved.
I hope that that helps others who may be having the same problem. If it's not exactly your problem, take a look at _Civ4Config/CivilizationIV.ini, anyways, since there are many other advanced settings that you can configure in there to try to solve problems.
