Update: The drivers are now available for download here.
ATI mobile graphics chips will soon have separate drivers, with software improvements bringing performance jumps of up to 50 percent, ATI promises. Upcoming versions 5.6, 5.7 and 5.8 will offer new features, but will also speed up the hardware.
Version 5.6 will bring "Catalyst Mobility" - or short "Catalyst M" - that will bring the feature set of the desktop driver plus some notebook specific functions, ATI said. Catalyst M will be updated every month and initially support only Windows XP systems in combination with Mobility Radeon X700 and X800 chips.
