ATI Tray Tools (ATT) is a freeware program developed by Ray Adams for ATI Radeon video cards.
ATI Tray Tools is an advanced tweaker-application that resides in the notification area of the Windows taskbar and allows instant access to video options and settings via a right-click menu.
It is normally used as an alternative to the more bulky official Catalyst
Control Center (CCC), but it can also run in tandem with it.
- Radeon HD 5800 support
