Shaded Vertices Per Second

What does this counter show?

This counter represents the total number of vertices that the Shader unit has processed per second. This includes all the vertices submitted by the user as any culling will happen after transformation.

What does a high value mean?

It is rare that a large value of processed vertices will have any effect on performance although, due to the fact that the Shader unit workload is shared between vertex, pixel and compute tasks, it might represent extra pressure on the total processing load. Reducing the number of instructions per vertex should ease this pressure.
