Indexed Draw Calls

The Indexed Draw Calls metric represents the number of indexed draw calls being issued from your application per frame.

Improving Performance

  • When the Indexed Draw Calls metric is high, see if you can optimize your application’s geometry to better batch vertices into fewer draw calls, specifically those that use glDrawElements or its modifications.
  • When the Indexed Draw Calls metric is significantly lower than the Draw Calls metric see if you can optimize your application to use indexed geometry passed to the glDrawElements API or its modifications, rather than glDrawArrays and its modifications. Additionally, check the Vertex Count and Indexed Vertex Count metrics to see how much data is being drawn without indexing to estimate the impact of such optimization.
