The Burning Crusade Hardware Performance Guide
World of Warcraft wasn't a performance monster when Blizzard first released the game in late 2004. Players with modest and even mediocre systems could all get passable frame rates in Azeroth. Blizzard has stated that World of Warcraft will eventually get graphical improvements to keep the game up to date, but those changes aren't coming in the game's first expansion pack, World of Warcraft: The Burning Crusade. With 8 million subscribers and growing, you don't need to push out advanced graphics and raise hardware requirements just yet.
