    Abstract: Apparatus and method for speculative execution of hit and intersection shaders on programmable ray tracing architectures. For example, one embodiment of an apparatus comprises: single-instruction multiple-data (SIMD) or single-instruction multiple-thread (SIMT) execution units (EUs) to execute shaders; and ray tracing circuitry to execute a ray traversal thread, the ray tracing engine comprising: traversal/intersection circuitry, responsive to the traversal thread, to traverse a ray through an acceleration data structure comprising a plurality of hierarchically arranged nodes and to intersect the ray with a primitive contained within at least one of the nodes; and shader deferral circuitry to defer and aggregate multiple shader invocations resulting from the traversal thread until a particular triggering event is detected, wherein the multiple shaders are to be dispatched on the EUs in a single shader batch upon detection of the triggering event.

    Abstract: Embodiments described herein provide an apparatus comprising a processor to divide a first projection into a plurality of regions, the plurality of regions comprising a plurality of pixels, detect errant visual content in a first region in the plurality of regions, determine a detail frequency rating for the first region, and apply one of a first rendering technique to the first region in the plurality of regions when the detail frequency rating for the first region in the plurality of regions fails to meet a detail frequency threshold or a second rendering technique to the first region in the plurality of regions when the detail frequency rating for the first region in the plurality of regions meets a detail frequency threshold. Other embodiments may be described and claimed.
