The ATI Catalyst 8.5 driver package is here, so I'll skip the introduction, jumping right to the part I am sure everyone is interested in - the performance improvements brought by this new version:


- Call of Juarez DX10: Performance increases up to 12% on systems containing an ATI Radeon HD 3xx0 series of products
- Halo: Performance increases by 10-30% across all of the supported ATI Radeon series of products
- Lost Planet DX10: Performance increases from 5 to 35% on systems containing an ATI Radeon HD 3xx0 series of products
- Stalker DX9: Performance increases by 20-50% when HDR is enabled in the game; across all ATI Radeon HD38x0 series of products
- World in Conflict DX10: Performance increases up to 25% on systems containing an ATI Radeon HD36x0 and/or an ATI Radeon 38x0 series of product. Higher performance gains are noticed on systems containing an ATI Radeon 3870x2 series of products.

Basically, all cards since Radeon 9500 are supported, but most improvements are targeting the last generations, of course. Here's more...

- Catalyst Control Center Component Video - This release of Catalyst introduces 480i and 480p support. These formats will be found in the predefied component video format list found in the Catalyst Control Center->Component Video->Advanced page.
- ATI Graphics Driver Uninstall Enhancement - This release of Catalyst introduces an update to the ATI uninstall utility.
- SECAM TV Out Support - This release of Catalyst introduces support within the graphics driver to enable TV output adhering to the SECAM standard.
- 1080p HDTV custom mode - This release of Catalyst 1080p HDTV display mode. This feature will be available for display devices that use an HDMI connector and is available under the Windows XP and Vista operating systems.
- Adaptive AA on OpenGL for Catalyst Control Center - This release of Catalyst introduces Adaptive AA for Orca Driver, geometry for alpha tested objects are now submitted multiple times to the hardware using the multi-sample mask feature to update one sample at a time in the frame buffer using centroid sampling. With each pass of the sampling position for textures is shifted to be at the location of the sample that is being updated in that pass.

...and it doesn't stop here, but I don't want to become boring, so just go to the official ATI drivers page, select your OS and card, then click on "Go." Good luck!
