AMD has released yet another beta Linux beta driver for the Catalyst 12.11 series.
While there isn't any official change-log for Catalyst 12.11 Beta 11 compared to the earlier 12.11 Linux betas, it's now available for download from
AMD.com.
The Catalyst 12.11 Linux graphics driver has been in beta going back to
late October. In mid-November was a Catalyst 12.11 Linux beta driver that
improved the OpenGL driver performance namely for Valve's Source Engine games coming to Linux.
