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 BFG 7900 GT OC card does very well here and is able to keep up with the ATI X1800 XT for the most part. Once the AA/AF is enabled, ATI does have the advantage in the minimum framerate but not by much. SLI performance is great with a pair of the BFG cards giving us a 66% performance lift over a single card.
