Viewing a Trace

You can view a trace by choosing Views > Trace. The Trace window displays a running list of the OpenGL function calls your application makes. The time value next to the function name gives you an idea of the performance cost of the call. Keep in mind that a lot of OpenGL calls set bits and are acted upon only at draw or flush time. This means that in addition to looking at the time for a particular function, you also need to consider the execution time of the next draw or flush function.

• “Making Sure You Use Functions Correctly”

• “Identifying Problem Areas in Your Application”

• “Managing Trace Data”
