- Half Life 2 Episode 1

The world of Half-Life 2 has amazed everyone with its great story, graphics and Valve's great support. Half-Life 2: Episode One is the first in a series of new adventures created by Valve that extend the Half-Life 2 single player experience. It details the aftermath of Half Life 2 and launches a journey beyond City 17.

Stepping into the hazard suit of Dr. Gordon Freeman, you face the immediate repercussions of your actions in City 17 and the Citadel. Rejoin Alyx Vance and her robot, Dog, to once again aid the human resistance in their desperate battle against the totalitarian alien menace of the Combine.

Episode One exposes Alyx's combat skills and knowledge of City 17. Battle side-by-side with her through Valve's first episodic game, a four-to-six hour adventure of greater density and detail than non-episodic releases.

We recorded a timedemo and used the built-in console to run the timedemo for each card. All tests we carried out at 1280x1024 with HDR shadows fully enabled. Antialiasing and Filtering modes were enabled through Nvidia's 3D control panel:

The Gainward 8600GT PCX 512MB's performance with AA/AF disabled was not all that good in comparison to the other cards, even though 75FPS can be considered a good framerate.

HDR Effects and AA/AF do have an effect on performance and again the Foxconn 7900GS performs better than the 8600GT until AF/6xAA.
