Why does Civ become unplayable when I install the latest Catalyst Drivers for my card?

I have painstakingly tried to fix this problem by going to the INCREDIBLE hassle of uninstalling the game, uninstalling my display drivers, reinstalling the game, reinstalling drivers x 2 with no fix.

I tried the art pack patch but couldn't find the crucial Art0.FPK.

I've had to revert to a 5 year old driver just to run the game.

This is unacceptable Firaxis!

Is there anything else I can try?
