Radeon 3D Performance: Gallium3D vs. Classic Mesa: Gallium3D, the graphics driver architecture started by Tungsten Graphics to overhaul the hardware driver support in Mesa, has been around for a few years but it is finally getting close to appearing on more desktop systems. Now that the Nouveau DRM code is in the mainline Linux kernel and its main 3D driver is Gallium3D-based, we will hopefully be seeing that adopted by more distributions soon -- it's already being flipped on with Fedora 13. On the ATI side the "r300g" Gallium3D driver that provides Gallium3D support for the R300-R500 (up through the Radeon X1000 series) is also being battered into surprisingly good shape. To see where the Radeon Gallium3D support is at for these older ATI graphics cards we have run a set of tests comparing the OpenGL performance under the latest Mesa 7.9-devel code with the Gallium3D driver to running the classic Mesa DRI driver.
