The Vertex Count metric represents the number of vertices passed by your application to OpenGL* draw calls per frame. This totals the counts passed to the draw calls.
- When the Vertex Count metric is higher than expected and fragment processing is not the bottleneck, check whether you can improve culling, or whether you can use LOD or other techniques to reduce geometric complexity.
- When the Vertex Count metric is low, try to increase geometric complexity as an alternative to expensive operations such as Alpha Test that might slow down the pipeline.
