Half-Life 2 Lost Coast, Prey

Lost Coast is the free technology demo that Valve created to show off their HDR rendering technique.  Because this method of doing HDR (high dynamnic range) lighting uses integer math instead of floating point, both ATI and NVIDIA cards can do both HDR and AA at the same time.

Once again the Asus G2 doesn’t do too badly, but not enough to play games at the highest screen resolution with a decent amount of details enabled. The emerging picture here is that the X1700 512MB is probably better suited as a mid-range gaming solution, rather than something to compete with the GeForce 7900 series.

Now let’s take a look at one of the most graphically intensive games to be released this past year: Prey.

Settings: High level shaders, 2x Anisotropic filtering, 2xAntialising.

Low details: 1024×768, low shaders, no AA or AF.
High details: 1024×768, high shaders, 2x AA 2x AF.

In these few Prey test results, we can see what the Asus G2 is capable of at a modest screen resolution of 1024×768. With low details it fares well with a playable frame rate of 44 FPS. But once you increase the shaders and details, performance drops 11 FPS to a still respectable 33 FPS.

The Alienware mALX is just here for reference. There’s no sense in comparing this SLI configuration to the Asus G2.
