Much Faster MSAA Anti-Aliasing Is Coming For R600g/RadeonSI

Marek Olšák posted a patch today to significantly boost the performance for games using multi-sample anti-aliasing (MSAA) on both the R600g and RadeonSI Gallium3D drivers.

The few patches are for using hardware MSAA resolves for non-trivial resolves rather than shader-based.

Exciting about the patch series, Marek noted, "one scene with 8xMSAA in HL2: Lost Coast goes from 8-9 FPS to 32 FPS on Evergreen & Wine/Nine."

The work is currently on the Mesa-dev mailing list but will hopefully end up in Git soon enough for benefiting early adopters and making it into the next stable release come September.
