The State Overrides pane shows all the available state overrides (see Override Modes Overview). These state overrides allow you to perform various "what-if" experiments to identify potential performance bottlenecks in your application. These experiments are performed within the System Analyzer and do not require any changes to your application code.
For different versions of OpenGL/OpenGL ES workloads, there might be different override modes available.
To apply an override mode, select it from the State Overrides pane.
