The information tab shows data about the calculated game performance.
If the current game has been recognized it will also show its name here.
An unknown game will not even attemp to apply any depth based shaders like SRBAO and FDoF.
In that case, the depth dependant options will be disabled and unavailable.
All other items in this tab come from the graph system, the very same system that draws the graph also keeps count of all the info about game performance.
