Why does High Frames Per Second Matter?

This is coming from someone who has yet to game on a truly high performance modern machine. So maybe that is why I have this question. But if the human eye only perceives 30-60 frames per second why does it matter that games run in +100 frames a second? Is it like 8K resolution, at some point we won't perceive the difference between these high resolutions unless we zoom in on the video.

Thoughts and explanations?...

  • I'm honestly here to see what the answer is cause I have no idea but I do think it's a great question and I think the answer will be equally as good

  • I can see a huge difference between 30 and 60 fps. Above 60 not so much, but it definitely feels much smoother. Especially in shooters like CS - aiming gets easier and more precise... 

  • there is a massive difference that I can tell with my naked eye between 30, 60, and 120 fps. Just moving a mouse on a screen, its obvious. 60 fps is def playable, but higher frame rates, beyond looking and feeling nicer overall, up to a certain point allow for faster reaction times and more accurate aiming.

  • I mean for me anything after about 80-90 frames per second looks the same to me so I am not quite sure why you would need 100+ frames per second except as a flex

  • For some it's aesthetics, for others it's both aesthetics and speed. It can help leverage a more competitive gaming. Unless you have a high-end system, generally and more honestly speaking though, anything above120 FPS is mostly for aesthetics. And in my opinion, anything above 90 FPS is also for aesthetics.

  • There's a few things you have to understand and I'll simplify it down.

    The notion that humans can only perceive 30-60 frames is false. When people talk about humans seeing in frames what they really mean is how many times can we perceive flickering light every second. For the average person, this is 60 or fewer flickers per second, but this is just one part of our vision.

    The next thing you have to understand is that video game frames are moving images. The limitation for processing light is no longer the deciding factor to sight because we have adapted to perceiving motion. Our motion vision is so advanced that if you were in moving it would be possible for you to see 500 frames from the corner of your eyes. Sure the center of your vision does a terrible job at this because it is made to pick up details, but this is where the last part comes in.

    We only care about frames in FPS games because our eyes will be constantly moving around the screen picking up different visual images. You are trying to keep track of your mouse movements, navigating the space, searching+tracking for players, et. Your brain will perceive all of this as motion allowing the player to pick up information faster. The smoother and quicker the images are presented to the player the better they will be at perceiving what is going on.  

    That is basically how our vision works with gaming, but does it matter for most people? There is a point like 200 fps where most people will agree to be comparable to real-world movement vision. Sure there will be people who can see passed this. However, even if you can perceive the differences in higher frames it doesn't mean that you will be able to react to the changes. 

  • It makes the motion look more seamless and more realistic.  60 Hz is absolute minimum.  Have not seen above 120Hz myself.  Below 60Hz video looks fuzzy when there is any fast motion.

  • I have never been particularly concerned about having the highest resolution or frame rate. As long as I can see it, then I am fine with it.

  • It is the buttery smoothness, you catch more detail with no motion blur, and reaction time in control is better. Even if you eye or mind don't see every frame you do see that is possible and is noticeable. It is very noticeable in high framerate video when they released The Hobbit movie in HFR where it looks like things are in fast forward yet moving at normal speeds at the same time. It matters when you experience it.

  • So you don't die before you even see it on your screen while playing Fortnite.
