Keep in mind we cannot visibly see what is on his screen, I've said before 30-60-120 it will not matter if you get 100% rendered frames. Now certains things happen and in almost any situation you will get 90% or less rendered frames, this imperfection is what the eye notices between 29.9 to infinite frames per second as "LAG" not to be confused w/ internet lagging or latency. Now the good thing about higher frequency is, if you are getting roughly the same rendering as 60 fps then because the images are @ 100% increased rate of speed it seems more fluid, mere milliseconds removed but it is all about blurring into a simulated true motion, which cannot be achieved atm by a video game. Similar to how you can watch some insanely awesome CGI movies etc and have perfect frames because it is playback and not rendering so all frames are 100%.
