how does screen hertz affect fps in games?

[James Wakeland]

if you have a 60 hertz monitor or flatscreen tv, it can go above 60 fps right? i thiiink it can but i dont know much about that.

[ForumTryhard]

60hz will only allow you to see 60 fps. There are 120hz or 144hz monitors though.

 

 

 

inb4 human eye can only see 60fps

No, it cant.
if your monitor can only display 60FPS (a 60Hz monitor) more FPS than that will make no difference

Refresh rate doesn't affect FPS unless you have VSync on. But if the FPS doesn't match the refresh rate or its factors, you'll have screen tearing.

no

1:1. I believe.

You can have the GPU push more than 60FPS, but you will not see more than 60FPS on the screen per se. Technically, you can, which in that situation it would be seen as screen tearing. But you will not be able to correctly perceive above 60FPS with a 60Hz panel.

fuck... ok thanks guys lol

Agree with all the above.

The more Hertz you get on your monitor the more it Hertz your wallet

A 60 Hz monitor can show 60 images per second.  

60 FPS is essentially 6 still frames of the game being rendered per second by your graphics card.

Your graphics card can render more than 60 FPS, but you're still only going to see the 60 images per second that your monitor is capable of showing.

The problem with having not tying framerate to refresh rate is screen tearing.  Imagine your GPU is rendering frames so fast that it's pushing out two so fast that you can see half of one frame and half of the next frame in the same image on your monitor.  This results in mismatched geometry, especially during rapid horizontal scrolling.

 

This is what screen tearing looks like

does that screen tearing like flicker off and on or is it constant?

its hurts your eyes but it kind of tears the image in half with the next frame in place. You don't want it. That's why if you have good hardware, you want to turn on vsync so you don't get it.

Screen tearing is when your monitor is refreshing the image at the same time your GPU sends a new image to display. The end result is two separate images being displayed at once and it appears as though the image has been "torn". It looks like this: 

 

 

It looks awful and really bothers some people (like me - to the point where I actually feel sick). 

 

By enabling Vsync, it only displays one frame per cycle from your GPU, matching the FPS to that of the refresh rate of your monitor, so you don't see this "tearing" effect.
