Fans of Ubisoft's Far Cry who are also 64-bit AMD processor owners will be pleased to hear that a version of the game optimised for these CPUs is now available. This version of the game was built on AMD64 based machines, and will afford the player 64-bit maps, longer view distances, and many other enhancements. Owners of the 32-bit version of the game can download the appropriate patches from AMD's site if they are equipped with Windows XP Professional X64.
By most accounts there isn't much in the way of extra game performance, but the 64-bit version has enhanced maps, better textures, and two new multiplayer maps designed for the 64 bit version of the game. The update comes in the form of a 485mb 64 bit upgrade file, and a 421mb pack that includes the new maps.
