Last week-end, I was visiting a friend, who had just received an Asus GeForce GTX 1080 STRIX OC; a graphic card which costs as much as a whole month of rent of my apartment! By the way, he was all proud to show me the power of his new gaming system. He flooded me with technical information, and how he was reaching over 100 frames per second on most games (at 1440p resolution, on a 144Mhz screen).
I am sorry buddy, but, I see no difference between 60 FPS and 100 FPS! We had an argue about this. He claimed it was much more fluid, and I told him it was not.
Between 30 and 60 frames per second, there is an undeniable improvement of the fluidity, I agree that. But I am sorry, above 60 frames, there is no perceptive gain at all. That is purely a placebo effect to me. You are told that your system can output a hundred of frames per seconds, and it gives you the impression that things are much better, but that is wrong. If you sit a guy in front of two screens, one at 60 FPS, the other at 100 FPS, I am sure he won't be able to tell what is what.
Now, I accept the idea that, a higher frame rate, might improve the reactivity of the game, from the moment you press a key, and it takes effects on the screen, but I disagree that it improves the fluidity.
