HL2: 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.
Without and AA and AF enabled, the X1900 AIW is able to perform at the same level as the X1800 XT and 7800 GTX. Once we turn those features on though, the performance level on the All-in-Wonder card drops significantly.
