Hi.
I use a Geforce 5600 FX Go and had similar problems as described above, but did'nt try anything from the forums yet. Since i often had problems with newer Games, using Shader 2.0+ I searched for a tool to force the game, running with another (hopefully faster) shaderversion. I found a tool called "nVHardPage".
Selecting the "compatibility" shader within nVhardPage from "DirectX->Shader Settings" and starting the Game, gave me an Error by Civ, that my System wouldnt meet the requirements and the game would be reconfigured. Besides a much improved performance, I only experienced graphic glitches. I dont know what the game changed exactly, but I got rid of the glitches only by deleting the folder under MyGames\Civilization IV (I suppose the .ini file would have been enough to delete, but well I was frustrated . The game just wouldn't recognize if I re-enabled the Shader 1.4+ by itself, or I did miss something . Maybe an analysis of the changes made by the game during reconfiguration process could help pinpointing an easier solution.
What worked:
I gave it another try and selected Shader 1.4 under "DirectX->Shader Settings" (don't forget to apply your new settings!), crossed my fingers and started the game again. Even on the huge Earth map, it didnt lag anymore as before and was playable, without any glitches, even with all details set to high.
(If this doesnt help on the first run, try deleting the "CivilizationIV.ini", or make a copy of the folder "Sid Meier's Civilization 4" within "My Documents\...\My Games\", delete the original - savegames may be moved afterwards - and start the game again )
I didnt test the worldbuilder, or wonder movies, its getting late over here.
A copy of the mentioned tool may be found here:http://downloads.guru3d.com/download.php?det=362
I hope this helps at least some of you. Give it a try and post your experiences.
Have Fun.
P.S.: For reference...my System Specs: Pentium IV 3,06 Ghz with 512 MB Ram, Geforce 5600 Go (128MB), Driver Version 77.77 (Laptop2Go)
