Last but not least, we have Valve's Source Engine, which drives Half-Life 2. HL2 is a game that offloads some of the work to the CPU, so it is a good test for the latest graphics cards as well as overall system performance. (And as a bonus, HL2 offers some serious "eye candy" for the gamer.) HDR was added to Half-Life 2 and the Source Engine during a recent update from Valve Software. This was a great addition, but it broke our previous timedemo for benchmarking. We updated the benchmark under our new testing environment with the demo DP_Coast_01.dem.
This is the only time that the ATI Radeon X800 XL does not win in every category. This is a testament to the power of the GTO.
