AMD has released some new WHQL-certified drivers at long last, as the Catalyst 13.12 drivers are available to download. These are pretty much the same as the 13.11 beta 9.5 drivers, however just now it's WHQL-certified. The 13.12 drivers include official support for the R9 290, 280, and 270 Series; and the R7 260, 250, and 240 Series. CrossFire Scaling has been improved in Call of Duty: Ghosts (multiplayer), Splinter Cell Blacklist, Metro: Last Light, and Saints Row 4. New Enduro Technology profiles have been added for XCOM: Enemy Unknown, Need for Speed Rivals, Total War: ROME II, Battlefield 4, Saints Row 4, Splinter Cell Blacklist, and FIFA 14. Support has also been added for CrossFire frame pacing, which should hopefully make things smoother on resolutions up to 2560x1600. Various issues have been resolved, which you can check out in the release notes at the source.
The AMD Catalyst 13.12 drivers can be downloaded at the AMD website.
