Additionally, vsync is on in fullscreen mode and your framerate will be bound to the refresh rate of your monitor or integer dividers of that. On a 60Hz monitor that is 60, 60/2, 60/3 and so on. When your game runs at let's say ~57 fps in windowed mode, the frames per second will jump down to 30 in fullscreen mode.
