Graphic card I recently bought a video game (Civilization IV) but although the intro movie (although not fluently) runs as well as the menu graphics are fine, as soon as the game starts the entire background on the monitor is black. It seems to me that the graphic card initially installed on the computer is sufficient (anyway the game was launched in the same year as I bought the computer) to the minimum graphic card requirements of 64-MB with Hardware T&L (GeForce 2/Radeon 7500 or better). Sounds are fine. Thanks for your support.
