Using The New Radeon Gallium3D 2D Color Tiling
Written by Michael Larabel in Display Drivers on 17 January 2012. Page 4 of 4. 15 Comments

Due to these problems, it is a bit premature to run through the full arsenal of OpenGL benchmarks to compare 2D color tiling.

When running Warsow at 1920 x 1080, the frame-rate with 2D color tiling had more than doubled in some cases. However, with the incorrect rendering, these results are not too meaningful.

OpenArena had rendered correctly, but it was not benefiting from 2D color tiling.

Try out the R600 2D color tiling patches at your own risk, but you may want to wait for them to bake a bit longer and land in the respective mainline code-bases of the Linux kernel, libdrm, Mesa, and xf86-video-ati. As a performance optimization that is more reliable, later this week will be some R600 Gallium3D benchmarks when the Radeon DRM has PCI-E 2.0 support enabled, which is still off-by-default in the latest Linux kernel.
