Eight-Way BSD & Linux OS Comparison
Now are some graphics tests between the Linux distributions...
Starting with Nexuiz, the fastest performer was actually CentOS 6.4 for the Radeon HD 4650 graphics card followed by openSUSE 12.3.
Mageia 3 managed a very slight lead over the other Linux distributions with OpenArena 0.8.8.
Fedora 18 was the fastest when it came to running Xonotic with high quality settings.
