Linux "Now that the kernel mode-setting page-flipping for the ATI Radeon DRM kernel module has been merged into the Linux 2.6.38 kernel and the respective bits have been set in the xf86-video-ati DDX, we're in the process of running new open-source ATI graphics benchmarks under Linux. Our initial results (included in this article) show these latest improvements to cause some major performance boosts for the open-source ATI driver as it nears the level of performance of the proprietary Catalyst driver."

First, Mesa is heavily CPU limited when it comes to fast GPUs. The one tested is so slow that i don't think that became much of a factor. It's probably not realistic to expect this kind of performance from a high-end card, though.

Second, this is the r300g driver which supports r3xx-r5xx hardware. AMD dropped support for all those cards a while back, so it's not like they can combine it with their current drivers. And they won't for the more recent hardware, because A) still not as optimized as the r300g driver is, B) heavily CPU limited right now, C) doesn't yet support even GL3, D) won't ever support all of GL, at least by default, because of software patents, and E) they would lose all competitive advantage in the workstation market which is where they want to sell cards for linux anyway. They won't simply release their current drivers as open source either, because of all the IP in them that they don't even own.

All that said, this was a very encouraging sign. Hopefully the drivers will continue to improve.
