I can't tell if this is a joke or not... The frame rate does not impact the sharpness. It just makes things like panning more clear.
The alternate slower frame rate is going to blur a lot more during the same action. Going from a high frame rate to a low one feels like reality versus a dream you're having where everything is a little harder to see, but you can't pinpoint how immediately.
I have a racing sim and a few 240hz monitors. I don’t know if it’s my eyesight but I can’t see any difference between 240 and 120. Definitely a difference from 60 and 120 though.
Not everyone notices a difference ofcourse. But it doesn't even have to be in perceived "smoothness" since higher refresh monitor should also have better motion clarity which can be just as important.
Old Disney got a reputation for quality by doubling (or more) the frame rate to 24 fps. Then Southpark comes along and taps into nostalgia for the mass produced TV animation by making their computers crank out choppy, low frame rate shows.
Above 60fps is really important if you want to play high ranks in competitive games. Other than that is just cool to have a smoother experience and you won't miss if you don't have it.
20fps looks very choppy unless there is a lot of motion blur. Where did you get this metric? and lower latency is often the main reason for higher framerates anyways
I'm no computer scientist, but I'd say if we add more motion blur it's probably going to increase the framerate. In fact, we should all just crank up the motion blur on all the games we play. Everyone just loves that motion blur.
Game devs, I hope you're listening. I know you already do this, though. So THANK YOU so much. Go ahead and leave that setting enabled by default. Everyone LOVES it.
