ATI is one of the first graphic providers to make a 64-bit driver that supports the Longhorn Display Driver Model (LDDM) – the Microsoft Vista revolutionary graphic driver standard – as well as the first to provide LDDM drivers for integrated graphics processors. By making LDDM drivers available more than a full year prior to Windows Vista release, ATI provides developers with a stable, feature-enabled and performance-optimized platform for application development.
