Half-Life 2: Lost Coast
Half-Life 2: Lost Coast (Direct X)
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 single card performance of the three options we show here are nearly a dead heat in Valve’s Half-Life 2: Episode 1. In this title though CrossFire is very efficient, with a 51% gain at 1920×1200 and a 56% gain at 1600×1200.
