i have a MSI FX5200. I have Day Of Defeat: Source, and a popup came up saying i need to update to the latest Nvidia version. I tried using MSI's latest version but the popup still came up and HL2 would just close if I clicked continue anyways. Well, i just went ahead and installed Nvidia's version, and now the saturation and gamma on videos are really high. the game and desktop are fine though. Any help? thanks.
