Abstract
Disclosed are methods and systems for intelligent adjustment of an immersive multimedia workload in a portable computing device (“PCD”), such as a virtual reality (“VR”) or augmented reality (“AR”) workload. An exemplary embodiment monitors one or more performance indicators comprising a motion to photon latency associated with the immersive multimedia workload. Performance parameters associated with thermally aggressive processing components are adjusted to reduce demand for power while ensuring that the motion to photon latency is and/or remains optimized. Performance parameters that may be adjusted include, but are not limited to including, eye buffer resolution, eye buffer MSAA, timewarp CAC, eye buffer FPS, display FPS, timewarp output resolution, textures LOD, 6DOF camera FPS, and fovea size.
