FPS
By default, the game is set to the maximum number of frames per second (250 FPS), which can have a large effect on the load on the graphics card on some older devices. For common home monitors, a value of 60 is plenty.
Reduce FPS when game is inactive offers to limit the number of frames in the game if the given window is not active.
