What happens if I have 80fps on a 144hz screen?

[Anton_22]

Hello.

I'm planing to buy a new monitor for my new pc. I've been looking at this one; Acer GN246HLBbid
A 144hz 1080p monitor. But I wonder what will happen if I can only reach 85hz in a game, will it display 60hz? Will it display 85hz? Should I use vsync to be available to display as high frame rate as possible?

Thanks!

144hz is the cap. Any frame rate you get at or below that is what you see. So if you're pulling 85fps in a game, you'll see 85fps on the monitor.

Picture a car that's limited to 144mph. If you're going 85mph, it's below the cars limit and you're fine Try going 145mph and the car won't do it.

As for vsync, it's not really needed on 144hz monitors. It would only be potentially useful if your minimum FPS is over 144 and you're seeing tearing. You can always enable it and see if you like it or not.

This is a good question to illustrate the appeal of Freesync (or G-Sync for Nvidia). In a non Freesync monitor, your GPU will put out 85 frames per second (or something of that order). Your monitor, regardless, will refresh 144 times per second. Therefore, roughly speaking, your monitor will refresh twice most of the time before the GPU provides a new frame- the monitor will show the same frame twice before the GPU provides a new frame. But, about 10-15% of the time, the GPU will provide a new frame after the monitor has shown the previous frame only once. Imagine the monitor showing GPU numbered frames like this:

1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,9,9,10,10,11,11,12,12,13,13,14,14,15,16,16,17,17,18,18,19,19,20,20...

So, most frames are shown twice, but frames 8 and 15 are only shown once before the subsequent frame is shown. It can be stated that the human eye can only identify 30 frames per second, so any changes beyond that frequency would not be detected. In one sense this is true, however... when there is the subtle change of a frame shown twice in some cases, but only once in other cases (as will always be the case in non Freesync/G-Sync monitors), there can be artifacts noticeable by the human eye. This has to do with instantaneous brightness and dimming of pixels lit for one cycle versus two, and is perceived as a type of discontinuous display. It is subtle but definitely noticeable.

Freesync/G-Sync does away with that artifact and provides a consistent one frame per monitor refresh cycle. The human eye doesn't notice the varying difference of 65 fps to 85 fps as the game slows and accelerates, and the possible artifacts of cycles per refresh is done away with, so there is no jarring affect. The result is a quite noticeably smoother video experience.

If u want 80fps and use 80hz u need AMD Freesync monitor(with Freesync compatible GPU)or Gsync Monitor(with Gsync compatible GPU)

Vsync idd will not improve framerate but sometimes get more stable fps and get rid of screentearing..

Best is Nvidia GTX 10 series Card and Gsync monitor but if u are on budget like I was then go with AMD. I am realy satisfied with my Lyama Red Eagle 24" FreeSync monitor and RX 480 8GB videocard,everything runs smooth but Nvidia does improve framerate more for now.. Though I don't know about the new AMD Vega GPU coming out soon (Februari)
