Improved video presets, available for the ATI Radeon™ HD 3000 and ATI Radeon™ 4800 Series, delivers a newly optimized video presets that users can select depending on what kind of video content they are viewing. Windows XP support: Edge enhancement, which adjusts the level of sharpness of video content and Noise Reduction, which removes ghosting artifacts while preserving details of the original video. The new slider controls can be found in the All Settings page of the Avivo Video tab found in the Catalyst™ Control Center
The new drivers also enable support for Hybrid Graphics in Windows XP. AMD's Hybrid Graphics tech lets users pair Radeon HD 3400- or 2400-series graphics cards with 780G and 780GX integrated graphics chipsets for extra performance and quad-display support.

In Windows Vista, gamers should find fixes in Call of Duty, Devil May Cry 4, Dirt, Hellgate London, Lineage II, Lost Planet, Mass Effect, Quake 4, Second Life, Unreal Tournament 3, and World in Conflict. In Windows XP, the list of game-related fixes spans Assassin's Creed, Age of Conan, City of Heroes, Company of Heroes: Opposing Fronts, Enemy Territory: Quake Wars, Lost Planet, and The Witcher.
