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 1920×1200 and 2560×1600 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 2560×1600 however the same setting at 1920×1200 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.
