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 theIndexed Draw Callsmetric is high, see if you can optimize your application’s geometry to better batch vertices into fewer draw calls, specifically those that useglDrawElementsor its modifications.
- When theIndexed Draw Callsmetric is significantly lower than theDraw Callsmetric, see if you can optimize your application to use indexed geometry passed to theglDrawElementsAPI or its modifications, rather thanglDrawArraysand its modifications. Additionally, check theVertex CountandIndexed Vertex Countmetrics to see how much data is being drawn without indexing to estimate the impact of such optimization.
