Is AMD's New 2D Acceleration Architecture Still Slow?

Earlier this week AMD released the Catalyst 10.6 driver that on the Linux side of the table had finally made use by default of their new 2D acceleration architecture, offered official support for Red Hat Enterprise Linux 5.5, and formalized their OpenGL 3.3/4.0 support. Since the release of the Catalyst 10.6 Linux driver, we have been running a new set of tests on their new ATI 2D acceleration architecture, but the results are not what you may expect when compared to the open-source ATI Linux driver.

Back in February we reported that the Linux Catalyst driver is using Direct2D code for their new 2D acceleration paths beginning with the Catalyst 10.2 driver release. Up until now, this new 2D acceleration architecture has not been officially communicated by AMD and would not be used by default unless enabling it via an AMDPCSDB (AMD
Persistent Configuration Store Data-Base) key called Direct2DAccel. Those testing out this new 2D acceleration for the Catalyst Linux driver experienced some success but others encountered various obstacles and problems with their 2D rendering. Four months later AMD is now satisfied with this new acceleration architecture and it is flipped on by default with Catalyst 10.6 and later. When using this new architecture there should be an "ATI 2D Acceleration Architecture enabled" line within the /var/log/Xorg.0.log file rather than "Using XFree86 Acceleration Architecture (XAA)."

There have been some positive reports based upon the vast feedback in these two forum threads: ATI Catalyst 10.6 Released and AMD Catalyst 10.6 For Linux Brings Changes while others are experiencing problems like the driver not even working. There has also been some ecstatic comments like "Direct2D is enabled by default and its bloody fast!" and "I must say that this is the first version of fglrx that's pleasantly surprised me. Good work, ATI/AMD." Source: Phoronix
