Typically when a game(or potentially any 3d application) is fullscreen,
that game(or 3d application) has exclusive control and desktop
elements(the desktop environment and the windows within) are no longer
rendered. As a result, frame rate is increased, latency is reduced, and
stuttering/jittering are reduced or non existent.
However, it's possible to "fake" fullscreen by using borderless windowed
mode which does not provide the performance benefits of fullscreen while
Basically what I'm asking is: Does JavaFX just disable window
decorations(title bar/resize borders) and overlays the application over
the OS's desktop or is it *truly* fullscreen?
