Ambient occlusion - how use

  Ambient occlusion (AO) is a shading technique that darkens creases, corners, and contact points to add depth and realism; it began appearing in real‑time games around 2007 and today ranges from cheap SSAO to high‑quality ray‑traced AO — you can safely turn it off in many 4K scenarios to reclaim GPU performance with little perceived loss when other lighting tech (like DLSS and GI) is active. Quick guide — key decisions before you toggle AO Performance vs fidelity: Do you need maximum frame rate at native 4K, or the last bit of visual polish? Type of AO: SSAO/HBAO are cheaper; ray‑traced AO is expensive but more accurate. Other tech in use: If you use DLSS or path tracing, AO’s visual contribution may be redundant. Answering those helps decide whether to keep AO on or off. What ambient occlusion is Ambient occlusion simulates how much ambient (indirect) light reaches a surface by darkening areas where geometry blocks light, producing soft, contact shadows that make scenes feel ...
