- 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.
Product and Performance Information
Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
