Half life 2 is no doubt the most anticipated pc game of all times.

Characters - Advanced facial animation system delivers the most sophisticated in-game characters ever seen. With 40 distinct facial "muscles," human characters convey the full array of human emotion, and respond to the player with fluidity and intelligence.

Physics - From pebbles to water to 2-ton trucks respond as expected, as they obey the laws of mass, friction, gravity, and buoyancy.

Graphics - Source's shader-based renderer, like the one used at Pixar to create movies such as Toy Story® and Monster's, Inc.®, creates the most beautiful and realistic environments ever seen in a video game.

AI - Neither friends nor enemies charge blindly into the fray. They can assess threats, navigate tricky terrain, and fashion weapons from whatever is at hand.

To measure performance we used the Video Stress Test(VST) that is available in the CounterStrike:Source beta available through Steam. We set all the details to the highest level and each time changed the resolution from 800x600 up to 1600x1200.

Since the game is very CPU dependent, we could almost ignore the results for 800x600 and 1024x768 resolutions. The true power of the VGA card is best seen at higher resolutions with HL2. That is, at 1280x1024 and at 1600x1200 gaming resolutions.

In general, the X1900 GT produced similar framerates with the XFX 7800 GTX at all tested resolutions, while the EN7800 GT trailed behind by only a few fps, except for 1600x1200 where it simply lacked the horsepower to keep up.

With AA and AF enabled, the lack of horsepower from the EN7800 GT becomes more evident.
