ATI releases new drivers every month to the public with new features, performance improvements and ofcourse with bugfixes for games and other issues. We compared Catalyst 4.10, Catalyst 4.11 and the last beta 4.12 Catalyst driver, which ATI claimed to be the best for Half-Life 2. The following games are used to generate performance results: Doom 3, Farcry, Need for Speed Underground 2, Return to Castle Wolfenstein, Unreal Tournament 2004 and last but not least Half-Life 2! We also selected five different timedemos for Half-Life 2, two timedemos from [H]ard|OCP and ATI and one timedemo from Anandtech.
