while playing games you probably have heard many times about g-sync technology. But what is this NVDR g-sync and what does it need? Today, I will discuss the matter briefly. v 
we all know about most of the monitors and GPU. We all know that each monitor has different refresh rates for each display. Currently, 90% of the monitor is 60Hz retresh. That is monitors are refreshed 60 times per second.Or it can not be wrong to say that they can change the maximum of 60 frames per secind. Now let's talk about GPU. Many types of GPU are available in the market. Since each ia a different power. there is a lot of difference in the render speed of each. For example, high-end NVDR GPU such as GTX 1070,1080p, or 1080i etc. GPU can render games at a very high frame rate. Fof example, 80 ir 100 FPS. But a little mid-range GPU, such as GTX 1030 or 1050, renders the game at slightly lower frame rate, For example, 40 or 60 fps. But the problem is here. At present, the monitir rate of 60 FPS refresh rates is no very high. Even if they are available they are much more expensive. So everyone is not able to do this type of refresh rate monitors. But we are discussing how the main priblem is how NVDR G-Sync works to fix it. 
What is NVDR G-Sync? Suppose that the monitor or display you have is fasr as 60 fps refresh rates. That means your monitor can refresh 60 seconds per second or take as 60 new frames Can not be more than and the GPU you have no your PC is a high and GPU such as GTX 1070 or 2080etc. In that case, while playing your most GPU , the game will render it at a much higher rate of 60 fps. Now think, your monitor does not support 60 frames per secoand, but your GPU as rendering more than 60 frames per second so that your monitor can see it. The problem that is happening in this situation is screen tearing. In the meantime, since your monitor reccivs more than 60 frames per secind but can not see it because it does not support it every time it is more than 1 frame or more than one image is viewed separately. This results in screen tearing. Screen tearing there is a lot of tear in the middle of the screen, a cut of a screen or a picture of the next frame in the middle enough to make the whole gaming experience worse. NVDR G-Sync is a feature of NVDR that lets high-end GPU slow down so that they do not render the game at their maximum power, or render at a lower frame rate or better, the monitor renders at the rate that supports the maximum refresh rate, So that the monitor supports it well and does not have any kind of screen tiring.
But here,s another problem. Now the new high-end games or too many GPU intensive games are in those times and GPU cannot be rendered at a maximum of 60 FPS. It this g-sync technology is used than the problems that previond menti mentioned will be reversed. It cab be seen your monity suppor 60 frames per second , but you is GPU cannot complete 60fps becausr the game is much more graphic intensive .Whebn g-sync is on your monitor needs to wait. For the frames to to show. Than. again, screen tiring will start at the station and lag. But this problem resikves AMD free-sync.
