AMD has released Catalyst 8.8 drivers. You can pick them up from http://game.amd.com. These new drivers bring with them a couple of new features.
One of these new features is Hybrid Graphics support for Windows XP users. To make use of this feature users will need an AMD 780G/780D integrated graphics motherboard and a Radeon HD 3400 series or HD 2400 series GPU installed on a separate graphics card.
Also seen in Catalyst 8.8 are new Avivo video features. Dynamic Gamma/Contrast correction, which is available on the Radeon HD 4800 series and improved video presets, available for both the Radeon HD 3000 series and 4800 series GPUs.
There are also a whole host of fixes, ranging from corruption in CoD4 when running in Quad CrossFire enable and with an HDMI 1080p display device connected to poor performance in Second Life.
