AMD has released its Catalyst 15.9.1 beta driver, a slight update over the recently released 15.9 beta driver.
The latter improved performance in the Fable: Legends benchmark and The Star Wars: Battlefront beta, but also gave rise to a severe memory leak bug that triggered when resizing windows. That bug is fixed in 15.9.1, so download and install via the source link to your heart's content.
Driver notes are below.
