Introduction
At the end of 2004, barely over 6 years since the release of the original Half Life, Valve unleashed the long awaited sequel upon the world. We stayed up late that launch night benchmarking the new game, worried that it would only run well on ATI cards, we were pleasantly surprised that Valve had made a Half Life 2 that ran very well on virtually all hardware with the exception of the GeForce FX.
A year and a half later, Valve brought out Episode One, an attempt at episodic content that was supposed to guarantee quicker game releases, more frequent updates to the story and a better overall experience for gamers. Performance changed a bit with the release of Episode One and its associated version of Valve's Source engine, and the game quickly became a regular part of our CPU and GPU test suites.
Once more, around a year and a half later, Valve finally released Episode Two, the second installment in the Half Life 2 episodic series. Armed with the latest version of the Source engine, we went to town on benchmarking the new game to see where things have changed, if at all.
Our experiences with Half Life 2 and Episode One kept expectations realistic this time around; Valve has historically sacrificed overall image quality in order to maintain playability on even the slowest hardware. What you'll see here today is that every single component we tested, down to the cheapest CPU and GPU, are more than enough to run Half Life 2: Episode Two. Of course having a faster CPU will allow you to extract more performance out of faster GPUs, and faster graphics cards give you the ability to run at higher resolutions, but the minimum requirements for playability are more than reasonable for any modern day system.
