The AMD Website now offers new version 12.2 reference drivers for AMD/ATI graphics cards. The new drivers offer Windows 7 and Windows Vista support for AMD Radeon HD 7900 and 7770 series GPUs and more. Windows XP users are told that support for their OS will come in AMD Catalyst 12.4, which is expected next month (though these new drivers were expected last month, as 12.2 means February 2012 in AMD's versioning scheme).
