As indicated late on Tuesday, AMD have released a Crimson 16.7.1 Hotfix driver which contains changes to the power distribution on their new RX480 cards. The main power changes, detailed on Tuesday, include a lowered current drawn from the PCIe bus and a new ‘compatibility mode‘ toggle in the Crimson UI which (if switched to ‘on’) will reduce overall power draw.
To offset the presumed performance loss from these power changes, AMD say they’ve squeezed a bit more out of the Polaris architecture; meaning boosts of up to 3% (based on internal tests on Total War: Warhammer, The Witcher 3, Far Cry 4, and Metro: Last Light).
This driver isn’t just for the RX480 of course. It also features fixes for DOOM (which should no longer have video corruption at resolutions above 1920×1080), and Hitman. Zoomed weapons in the latter should no longer exhibit video corruption in DirectX 12 mode.
Here are the remaining known issues. 380/380X owners will be once again disappointed to see no sign of a fix, or even much acknowledgement, of the persistent ‘black screen’ bug that has plagued these cards in select games for more than six months.
