Users are encouraged to install AMD Catalyst™ 15.5 Beta, now available with optimized performance for The Witcher 3: Wild Hunt. In addition to this graphics driver, there are additional manual steps AMD Radeon™ customers can take to further improve the performance of The Witcher 3: Wild Hunt.
HAIRWORKS - TESSELLATION LEVELS
AMD Radeon™ users who wish to use the HairWorks
feature are advised to manually create an application profile that will
optimize the tessellation level of The Witcher 3: Wild Hunt to 8X or 16X. This
profile will streamline the workload presented by the application’s dynamic
hair, improving performance without compromise to image quality
OPTIMIZING AMD Crossfire™ and ANTI-ALIASING
Significant improvements to the performance of The Witcher 3: Wild Hunt can be realized on AMD CrossFire™ technology configurations by adjusting the anti-aliasing settings.
Users are encouraged to change the EnableTemporalAA setting from TRUE to FALSE in the application's Rendering.ini file. This configuration file can be found in the \bin\config\base folder of The Witcher 3: Wild Hunt's installation directory.
Users are strongly encouraged to alter this setting, as flat to negative multi-GPU performance scaling may be encountered if this optimization is not performed.
Alternatively, users can access The Witcher 3: Wild Hunt's postprocessing options menu and set anti-aliasing to off.
FULL SCREEN EXCLUSIVE MODE
AMD CrossFire™ technology requires that an application utilize full screen exclusive mode to enable multi-GPU performance scaling. The Witcher 3: Wild Hunt may default to the windowed or borderless windowed modes, which will prevent users from realizing the full performance of their system.
Full screen exclusive mode can be configured by setting the display mode option to full screen in graphics options menu of The Witcher 3: Wild Hunt.
