A new version of Catalyst driver is available for download, improving performance and providing some new features.
After Nvidia, it is indeed the turn of AMD to update their graphics drivers. No version is finalized by against, since we are talking of a beta 14.6 version here.
This latest announcement improves gaming performance for Murdered Soul Suspect (up to 16% on a configuration of Radeon R9 290x in 2560 x 1600 pixels with 4x MSAA) and for Watch Dogs (up to +28% on a configuration of Radeon R9 290x in 2560 x 1600 pixels with 4x MSAA).
It also adds support for the Mantle technology for AMD mobile graphics solutions. One can thus expect 21% performance in Battlefield 4 in 1366 x 768 pixels with a Radeon HD 8970M, 14% more in Thief in 1920 x 1080 pixels with a Radeon HD 8970M and 274% more in Star Swarm in 1920 x 1080 pixels with HD Radeon 8970M.
It is also accompanied by optimizations for Eyefinity (multi-screen) technology with, among others, the possibility to combine screens with different sizes and definitions, can choose to use the display area (display identical, best rectangle or different application windows).
Note finally that hardware acceleration for decoding JPEG has been extended to all processors in socket AM1. Introduced with version 14.1, it was previously reserved only for A10 models.
