When Hotspot mode is enabled, the metric values are an average/weighted value for the selected region. To determine the affecting bottleneck in each grouping, view the 3D pipeline located in the bottom right-hand side of the Graphics Frame Analyzer
window. Any portions of the pipeline that are marked in red are considered the main bottleneck and any yellow portions indicate a secondary bottleneck. The amount of green, yellow, and red that make up any pipeline item directly correlates to the number of events that are experiencing that bottleneck, that is if grouping by stated and only 50% of events in a grouping have a main bottleneck at Thread Dispatch, then only half of the Thread Dispatch bar will be red. Any pipeline state can experience a primary, secondary, or no bottleneck in the same grouping, meaning the state can be marked with red, yellow, and green in varying amounts. Selecting the bottleneck in the 3D pipeline offers helpful suggestions on how to fix the problem.
