Hi,
I made a simple example of a rolling ball, and it works fine (60fps) in normal mode, but when i switch it to fullscreen, frame rate drops to 30-40. Why is this happening, I have only one sphere and one plane on the scene(AwayStats: 484poly), even without lighting and shadows.

any ideas?
Many thanks for considering my request,
p.s. sorry for my english
