Latest Radeon Graphics Results On Ubuntu 14.10 Are A Bit Concerning
With OpenArena, the performance wasn't changed a lot until it came time to use the latest Ubuntu 14.10 + Git state where the frame-rate had receded by a lot.
With the newer OpenArena 0.8.8 release, the performance was in its worst state with the newest Ubuntu 14.10 + Git packages using Linux 3.18 / Mesa 10.5-devel.
World of Padman, while another ioquake3 engine game, also showed a significant slowdown when using the very latest graphics driver code.
