Half-Life 2: Lost Coast

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.

The Alienware Aurora m9700 with SLI enabled blows away all other configurations we’re testing. At 1920×1200 resolution, we have spectacular average frame rate of 48 FPS and an acceptable minimum of 21 FPS. Compared to the NVIDIA’s other top-end mobile GPU, the Go 7900 GTX lags behind 10 FPS in both average and minimum FPS. It’s very smooth sailing for the Go 7900 GS in SLI.
