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 Microsoft DirectX* and 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.
