Radeon WattMan section of the Radeon Software control panel does allow the user to select preset profiles such as Power Saver, Balaced or Turbo. If we do need to tweak even further, AMD has put to our disposal a secondary BIOS (via the on-board switch), which does enable three more power profiles:

Enhanced Sync is a new Vsync mode, which seeks to combine the optimal display refresh sync behaviors for multiple situations. When a game’s frame rate is exceeding the display’s peak refresh rate, Enhanced Sync does not limit the game performance; instead, Enhanced Sync does show the most recently completed frame on each display interval, reducing input lag without introducing the usual tearing artifacts common when Vsync is disabled. The Enhanced Sync feature does operate well on fixed-refresh displays, but can also operate along with FreeSync variable-refresh monitors to provide even better experiences.

Radeon RX Vega cards do fully support FreeSync, along with compatible displays; FreeSync displays are meant to solve one of the long-lasting performance problems with PC gaming: lack of sync between the game’s animation loop and the display’s update rate. FreeSync does avoid the described issue by synchronizing the display’s update cycle with the GPU; when the GPU has a new frame ready to display, then the monitor will display it, quickly and without the horizontal tearing seams, which are a result of a disabled Vsync. The compatible FreeSync displays do feature variable refresh rates (usually from 30Hz to 90Hz). If the displays do have a broad enough operating range, they incorporate an added benefit; these are capable of supported one of the extended FreeSync features, which is known as low-framerate compensation (LFC). LFC was designed to work in order to reduce stutter when framerates do drop below the monitor’s minimum refresh rate, effectively extending the FreeSync range even further.
