Ubuntu 13.04 Will Improve Gaming On Open-Source GPU Drivers
Fedora 17 is faster than the newer Fedora/Ubuntu Linux releases tested due to the newer releases shipping with a Mesa i965 DRI driver that supports anti-aliasing for the Intel driver with Nexuiz.
Ubuntu 13.04 was the fastest Linux distribution benchmarked over Fedora 17 and Fedora 18 for both OpenArena releases.
Ubuntu 13.04 was also the performance leader when running World of Padman.
