I can see beyond 60 easily.
I can too but my loving new screen tares.
What resolution does the human eye have at 20x20 vision
I can easily tell the difference between 30fps and 60fps. I can't see a difference past 120, though.
Have you tested on a screen that can support up to 120Hz?
If this were true 3D technology simply would not work. At minimum it requires 120Hz.
