BatonRogue writes "Apparently ATI provided a few Half Life 2 benchmarks to the press and some websites are actually using the benchmarks for their Half Life 2 performance reviews. AnandTech and HardOCP seem to be the only reputable sources of Half Life 2 performance data as they both put together their own benchmarks representative of Half Life 2 gameplay. AnandTech apparently went through every Half Life 2 level and put together a list of the 11 most stressful levels and then created 5 demos, while HardOCP put together two long benchmarks for their review. AnandTech and HardOCP's results appear to agree with each other, while the ATI-backed benchmarks show ATI with a huge performance lead in Half Life 2. Apparently (according to the AnandTech article), ATI was allowed to make their demos while at Valve before Half Life 2 was released, while Valve would not let NVIDIA remove any data from their time at Valve until the game was released. Politics at work as usual."
