The latest Phoronix article covering AMD's latest graphics processors on Linux was earlier this article in pointing out the Radeon R9 270 is far from perfect. One of the big problems with any Radeon HD 7000 series or newer GPU is the poor 2D acceleration performance with the open-source Linux driver, but performance improvements are coming.

Yesterday saw a SteamOS Linux update that shipped a new AMD Catalyst Linux driver that reportedly worked much better for popular Steam Linux games. That driver update led Valve to officially support AMD (and Intel) graphics on SteamOS. For non-SteamOS Linux users, that new AMD driver update is available for other distributions.

As shown in our recent open-source GPU driver comparison, the RadeonSI Gallium3D driver still has a long ways to mature to be more competitive against the R600g driver and the Catalyst binary driver. Fortunately, one of the major 3D performance-boosting features (HyperZ) appeared on Tuesday in mailing list patch form.
