Urban Terror is another non-demanding ioquake3 game, which yielded the open-source AMD Linux driver running at around 80% the speed of Catalyst.
The Warsow game performance was also decent for the open-source driver, though the higher-end Radeon HD 5830 had a wider performance margin than the closer to mid-range HD 5770 graphics card.
