Half-Life 2: Episode Two

Publisher: Valve

As one part of our game of the year 2007, Half-Life 2: Episode Two set a new high in narrative and gameplay for the series. Using Valve's widely used, albeit not overly hardware intensive, Source engine that also features as a part of legendary games like Counter-Strike, Team Fortress 2 and Portal, we were keen to feature its performance here too.

The Source engine is the most scalable engine we test. While it still supports only DirectX 9.0, it features effects like dynamic lighting with HDR effects, motion blur, advanced Havok Physics and high model details.

Episode Two took Half-Life out into large open environments for the first time and we test with Gordon running through a large open level that combines forest and houses with explosions and physics.

All in game detail settings are set to their highest levels, with HDR enabled and, for anti-aliasing, MSAA was used and controlled from inside the game.


In Half-Life 2: Episode Two the extra MHz and memory bandwidth nets about 12 frames per second more performance, a nice jump and it's clearly the fastest thing on the table. The overclock has given us about 13 percent more performance and compared to a 3.2GHz quad core Penryn about 10 percent more.
