[[ | <!--'''Ambient Occlusion (AO)''' is a type of [[lighting]] technique applied in-game to create more realistic lighting. AO simulates soft shadows created by two surfaces that are close together. Ambient occlusion in games is normally accomplished through '''[[Wikipedia:Screen Space Ambient Occlusion|Screen Space Ambient Occlusion]]''', which is a simplified way to fake realistic AO with shaders in a process fast enough for real-time rendering. SSAO is a [[DirectX]] 9.0c shader, so it will only be available on fairly modern video cards.--> | ||
<!--Ambient occlusion is currently only available for NVidia cards using the NVidia drivers. It is very resource-intensive and will cause a significant reduction in framerate on older video cards. | |||

All [[Source]] engine games except [[Portal]] support ambient occlusion. This may be because AO would not render correctly through Portals. | All [[Source]] engine games except [[Portal]] support ambient occlusion. This may be because AO would not render correctly through Portals.--> | ||

Ambient occlusion cannot be controlled through the video options within a Source game. AO can be turned on with NVidia cards using the NVidia drivers. | Ambient occlusion cannot be controlled through the video options within a Source game.
