nVidia Optimus system: On integrated Intel HD 3000 overlay is slower by 0.40 ms (16.05->16.46) and present is mush slower (0.05 -> 0.19). But on discrete nVidia 540m overlay is more than 2 times faster (14.1->6.5 ms rendering and 4.28->2.55 ms present time)!
Also +1 disadvantage - it's impossible to take screenshot with video.
