What does it mean to have a v sync setting in the game settings?

Vertical synchronization. 1. To know what vertical synchronization is, you must first understand how the display works.

All the images on the monitor are scanned line by line, whether it is interlaced or progressive, the display, there are 2 synchronization parameters - horizontal synchronization and vertical synchronization.

2. What is horizontal synchronization? What is V-sync?

Vertical and horizontal are the two basic synchronization signals in CRT, the horizontal synchronization signal determines the time it takes for CRT to draw a line across the screen, and the vertical synchronization signal determines the time it takes for CRT to draw from the top to the bottom of the screen and back to its original position, and it is precisely the vertical synchronization that represents the refresh rate level of the CRT display!

3. Key parts.

Why does turning off the VSync signal affect the FPS values in our CS? The reason is not complicated at all, first of all, what is the general screen refresh rate of our operating system? Probably around 85, then the graphics card will send a vertical synchronization signal every time according to the frequency of 85, and the time interval between the signal and the signal is the time of a screen of images written with a resolution of 85.

If we choose to "wait for the VSync signal" (that is, what we usually call "VSync on"), then in the game, maybe the powerful graphics card quickly draws the image of a screen, but without the arrival of the VSync signal, the graphics card cannot draw the next screen, and can only be drawn when the signal of 85 units arrives. In this way, the FPS is naturally constrained by the operating system's refresh rate operating value.

And if we choose "do not wait for the VSync signal" (that is, what we usually call "turn off VSync"), then after the game has finished a screen, the graphics card and the monitor can start to draw the next screen image without waiting for the VSync signal, and the strength of the graphics card can be fully exerted.

However, but, but, don't forget that it is precisely because of the existence of vertical synchronization that the game process and the refresh rate of the monitor can be synchronized, so that the picture is smooth and the picture is stable. The elimination of the VSC signal can be exchanged for faster speed, but in terms of image continuity, the performance is bound to be compromised. This is also the theoretical reason why many friends complain about the discontinuity of the picture after turning off the vertical!

Vertical synchronization. Function: For high-end graphics cards to play games with low requirements, it is best to turn it on; Generally, the graphics card plays games that require a relatively high number of collisions, and it is best to turn it off; High-end graphics cards to play demanding games are also best turned off; Low-end graphics cards play games with low requirements, both on and off.

V-sync has nothing to do with the graphics card whether it is on or not, V-sync just ensures the picture, because the display and the graphics card output frame rate.

Being out of sync can cause the picture to tear, and V-Sync is used to solve this problem, which locks the frame at 60.

If your hard laugh judgment can't reach a stable 60fps, Zifan recommends that you don't turn it on, it's useless to turn it on, if your hardware won't be lower than 60fps at all, and the screen tear looks uncomfortable, the monitor is not G sync can be turned on.

The game options are designed to best suit your configuration, and if your hardware keeps up, the graphics can be as good as they can be, and the gamer will experience better gameplay. In this case, is this vertical synchronization comfortable for you to open and play early or not to play? How comfortable and how to come, this is the true meaning.

If you feel that the mouse is significantly delayed, it is recommended not to turn it on. V-Sync is an option added to prevent screen tearing in 3D games. If you don't turn it on, it's normal, and it's really not necessary to turn it on.

gamesVertical synchronization. Do not open.

The "synchronization" of vertical synchronization is obviously to make the refresh rate of the game screen.

Synchronizes with the refresh rate of the display. Definition of V-Sync: A coordinated number of frames.

and refresh rate technology, which allows the display to delay input to the picture and wait for the graphics card to render.

Introducing Vertical Sync.

I always see the setting of VSync in the game, and the newcomers are confused: what is VSync?

Vertical synchronization is easy to understand in the literal sense of the word, but to whom is it synchronized? This brings us to the problem that "V-Sync" solves: screen tearing. And the synchronization is to synchronize the refresh rate of the game screen with the refresh rate of the display.

When do I need to turn it on?

I used a top-of-the-line graphics card, but I always encountered a tearing picture? Go out and turn right and click to turn on Vsync, no thanks!

Many gamers may not understand that their own computer configuration.

Especially the graphics cards are very high-end, why is this still happening. In fact, the more high-end the card is more likely to have this situation. On the high-end configuration, you can get higher frame rates for smoother graphics, but the refresh rate of the display can't keep up with the refresh rate of the game itself.

It's better to open.

Vertical synchronization. It is to limit the number of frames on the screen.

The role is to keep the fps (frame rate) at the same refresh rate as the display.

Same, to prevent frame skipping and screen tearing.

The main difference is that those games that run at high speed, such as live and fps games, can prevent the screen from tearing when the game screen moves at high speed after opening, of course, if the number of fps of the game screen can reach or exceed the refresh rate of your monitor, then the number of fps of the game screen is limited to the refresh rate of the monitor.

If you can't reach it, there will be different degrees of frame skipping, and the bigger the gap between FPS and refresh rate, the more serious the frame skipping will be. After closing, except for high-speed games, there is basically no screen tearing in other games.

How V-Sync works:

from the CRT display.

In terms of display principle, a single pixel forms a horizontal scan line, and the horizontal scan line is stacked in the vertical direction to form a complete picture.

The refresh rate of the display is controlled by the graphics card DAC, which generates a v-sync signal after the graphics card has completed scanning a frame. What we usually call turning on VSC means that the signal is sent to the 3D graphics processing part of the graphics card, so that the graphics card is restricted by the VSc signal when generating 3D graphics rolling.

When the game screen has a "tearing" feeling, turn it onVertical synchronization. If there is no "screen tearing", you do not need to turn on V-sync.

For players who are confident enough in the configuration of their own computer, it is recommended to turn on "V-Sync" and "Triple Buffer", which are very helpful to eliminate screen tearing and lag. However, if your configuration is not in place, or you find that there is a serious delay after turning it on, then you can turn it off decisively, and you still need to upgrade the device to solve the problem.

When we choose"Wait for the Hang Sun Straight sync signal"(i.e., turn on VSh), the graphics card will wait for the VSC signal before drawing the 3D graph, and when the signal arrives, the graphics card will start to draw the 3D graph, if the graphics card is strong and has completed rendering the frame before the next VSync signal arrives, the graphics card will pause the processing and wait for the next VSC signal to arrive before starting to render the next frame.

It can be seen that when the V-sync chain is turned on, the game's FPS is subject to the refresh rate.

For high-end graphics cards, the performance is limited.
