Episode 1 is the last expansion of Half-Life 2 which Valve currently distributes through Steam. In this test we have used the resolutions of 1920x1200 and 2560x1600, along with 4x anti aliasing and in the other test HDR enabled. We always keep anisotropic filtering set at 16x. The demo we use is trdem1 which is provided by The TechReport.

Lost Coast is one of the first expansions of Half-Life 2 that was released by Valve. The short level is more of a technological showcase than of an actual game. The tests with Lost Coast were executed using hocbench at resolutions of 1600x1200, 1920x1200 and 2560x1600 with anti aliasing at 4x and anisotropic filtering at 16x.

There is without doubt a large performance advantage for the overclocked XFX cards. Performance scalability moving to higher resolutions is also quite impressive, but we still see drops in performance as moving to higher resolutions directly affects video cards and increases their workload.
