Your naked eye cannot see 60FPS. You can achieve more FPS if you turn Vsync off. But if you have Vsync on @ 60Hz you will only get 60FPS. 75Hz 75FPS....

right, you cannot perceive fps higher than the refresh rate, even IF you could see above 60fps.

Most people can't see above 60fps. I doubt your refresh rate is 60 or less

Actually DuckieHo posted something awhile back saying that humans can detect a lot more than 60FPS. It sounded true n all.

But yes, if Vsyn is turned ON then you cannot achieve anything above your refresh rate. If it is OF, you can.....providing the GPU is capable of course.

actually the refresh rate is as often as the screen will update the image (so effectively yes thats the fps)

However your gpu could produce 100's of fps but the monitor will only show the frames at its refresh rate, still higher the gpu produces frames the smoother the image will look.

ie if the gpu prodeces 120 fps and your display is 60 hz, then every 60 ms the screen wil be updated with a new image, missing the ones that it can't keep up with but not noticeable to you

IF your gpu produces 30 fps, the monitor will still update every 60 ms but of course 120 ms will show the same image as the gpu hasn't produced a different image yet
