Why do not the 60 fps feel fluid?

I have a question I take fortnite as an example because many of you know that

I have a 144hz monitor

and I notice these also quite normal now eg in fortnite when I reach the certain number of fps but I do not reach much fps (because I currently have no video card but soon get me a hole)

however, I always have more than 60 fps and when my fps are in the 60-80 range then the game does not feel fluid anymore even though it's 60 fps

what is the reason that the fps does not feel fluid should I put my monitor in the settings 60 hz?

with my friend they feel fluent or on youtube videos.

and my friend has a 60 hz monitor

Yes, this is clearly s.Monitor, s.besten because because settings limit the frame rate to 60 Hz

Get a 144hz monitor, is expensive YES but it's worth it anyway.
It makes a significant difference to a 60 hz monitor.
"It should be liquid 60hz at 60 Fps is actually relatively good.

Your monitor has 144Hz, which means that the image that appears on the monitor is updated 144 times a second.

In turn, if you have 60 frames per second (FPS) and your monitor refreshes the image 144 times a second, it logically requires 144 frames per second (FPS) to have a new image for every screen update.

However, you have "only" 60 frames per second (FPS) and so only a new picture will be displayed every second screen refresh.

Rukelig looks like that to us humans.

MfG and hopefully it was not too complicated.

Thanks, I'll try it now
