Valve continues to impress us with additions to their Source engine and the latest episode in the Half-Life 2 franchise adds excellent outdoor environments. Testing was performed at 1920x1200 and 2560x1600 with 8x anti-aliasing and 16x anisotropic filtering. All game settings were at their maximum level.
When testing Half-Life 2 8x anti-aliasing was a little too much for both cards when running 2560x1600 however the same setting at 1920x1200 was perfectly playable on the overclocked X2. An average of one hundred and six frames per second is excellent although there were some significant drops into the twenty-six frames per second range which were a little surprising.
