AMD has launched their first WQHL-certified Catalyst graphics card driver update since December 2014, bringing a heap of new features and performance updates across the board, as well as the usual array of bug fixes.
The Catalyst 15.7 WHQL drivers bring a range of existing features to older Radeon graphics cards. Frame Rate Target Control, which allows you to limit the maximum frame rate output of a GPU to reduce power consumption and temperatures, is now supported on all GCN-based cards higher than (and including) the Radeon R7 260. Virtual Super Resolution is also now available for the R7 260 and higher, as well as AMD's A6-7400K desktop APU and higher.
For those looking at purchasing a FreeSync monitor, the Catalyst 15.7 driver now supports AMD's adaptive refresh rate technology on CrossFire systems. CrossFire compatibility itself has also been improved, now allowing users to CrossFire a Radeon R9 290X with an R9 390X, both of which are essentially the same GPU.
As for performance improvements, AMD claims users with older graphics cards should see some gains compared to both the 15.6 beta drivers and the older 14.12 WHQL drivers. AMD also lists some new CrossFire profiles included with this driver, although many of these profiles have been added in previous beta drivers.
Alongside releases for Windows 7 and 8.1, AMD has also released a version of the Catalyst 15.7 drivers that supports Windows 10, WWDM 2.0 and DirectX 12. AMD has labeled this driver a "technical preview", with official support to come when Windows 10 launches on July 29th.
