Radeon R600 Gallium3D MSAA Performance Update
With Urban Terror was a similar issue to Padman on the HD 6870, but for this other ioquake3 game the only graphics card where MSAA was in a working state was the Radeon HD 6450.
When running Xonotic with high quality image settings, the results again were as expected for the Radeon R600 Gallium3D driver.
Additional Gallium3D / Mesa MSAA tests atop the latest code are forthcoming for various GPUs, including for Morphological MLAA. Also being toyed with is a comparison of the AA performance between the open and closed-source OpenGL Linux graphics drivers.
