Shader Processing Load

This counter represents the average workload of the Shader Processor, i.e. when it is processing vertices, pixels or compute. This average is calculated across the currently selected time range, regardless whether the GPU is active or not. To get the most from this counter, you should inspect its value in periods where Vertex, Pixel or Compute tasks are active.

A high value indicates that a large percentage of the Shader's workload has been spent processing vertices, fragments and/or compute kernels.

If this value is high, then you should refer to specific loads ("Processing load: Vertex", "Processing load: Pixel" and "Processing load: Compute") to see which type of processing load is bottlenecking your render.
