Identifying and Solving Performance Issues

OpenGL Driver Monitor is not the primary tool for analyzing performance issues in an OpenGL application. It’s the backup tool that experts use when Shark and OpenGL Profiler don’t reveal the cause of a performance problem. This chapter assumes that you have already used Apple’s other tools to analyze your OpenGL application.

The strategies described here can help you identify the most common problems that occur in OpenGL applications. Keep in mind that analyzing difficult performance problems is more of an art than a science. Although you’ll want to start with these basic strategies, you’ll need to devise additional ones tailored to the type of problem you see, and to whether you are trying to solve a driver issue or an application one.
