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.
Single card results are pretty tight, but SLI again has a big performance advantage here with 53% faster average frame rates.
