Phoronix posted some fresh MSAA benchmarks of the Gallium3D driver from Mesa 10.1-devel and using a Cayman-based high-end AMD Radeon graphics card

It's been a while since last looking on the anti-aliasing performance of the R600 Gallium3D driver so for this article we have some fresh MSAA benchmarks of the driver from Mesa 10.1-devel and using a Cayman-based high-end AMD Radeon graphics card.

The purpose of this testing is to just provide some new benchmarks of what users of the open-source Radeon Gallium3D driver can expect when enabling Multi-Sample Anti-Aliasing. MSAA can be enabled either via from the game/application itself or for easy testing purposes can be controlled on recent Mesa releases from the GALLIUM_MSAA environment variable or the functionally-identical __GL_FSAA_MODE environment variable.
