Why do I feel stuttered when the frame rate is high when VSync is turned off?

Turn off V-sync.

The frame rate is high, but you feel stuttered, because your current closed data makes the current frame rate fluctuate, so the phone is stuck.

Because after turning on VSh, it will sacrifice the performance of a part of the computer to maintain the smoothness of the picture,VSync is mainly to keep the frame rate of the picture stable at the same screen refresh rate,So in the case of not turning on VSh, the game may have frame drops, etc.,People have the illusion of stuck,In fact, if the FPS of the game is higher than the frame rate of the monitor,Then there is not much difference between turning on VSync and not turning on VSh, you can**Game Gaga to monitor your hardware status, Understand the working status of your computer's CPU and graphics card and other hardware when playing games, and you can see effective information such as occupancy, temperature, frequency, etc., so as to easily understand the reason for your computer's lag.

Turn off the VSync frame but feel stuck, this may be caused by you after changing the settings, the overall parameters are unstable, it is recommended to restore the factory settings.

Hello, my friend turns off the frequency of vertical synchronization, and if you feel that the lag is high, it will definitely affect a certain speed, so there will be a lag, I hope it can help you.

The reason why you feel that the phone is stuck is because the smooth screen switching function is not turned on during use.

If Wan Ning feels stuck, it may be that his network speed is a little bad, and you can readjust it.

Is VSync the same as a frame lock? V-sync simply synchronizes the graphics card's output frames with the monitor's refresh rate. The monitor is refreshed once, and the graphics card stealth booth outputs one frame.

A turnip, a pit. There will be no refresh of the monitor and the graphics card will output 2 or 3 frames. This avoids tearing of the moving picture.

For example, if the graphics card outputs 2 frames in a refresh cycle (simply put, it is a picture), the result is that the top half of the screen displays frame 1, and the bottom half displays frame 2, and the picture will be "torn". If your graphics card is capable of 100 fps and your monitor is at 60Hz, then the game's fps will be limited to 60 fps (sync with the display) when VSync is turned on. Does it reduce the hardware requirements?

You can make a high-performance graphics card run at a lower performance, but don't expect to get a lower graphics card to output a higher frame rate (at the same game resolution or effect level). Why does it drop frames when it is turned on? If the graphics card is unable to output a single frame during a display refresh cycle (usually the GPU performance is poor), it will wait for 2 refresh cycles.

If the output is still not available within 2 cycles, it will wait for 3 cycles (if it is not possible, 4 cycles, 5 cycles). For example, if your monitor refresh rate is 60 fps, the ideal game will run at 60fps after it is turned on. However, if the performance of the graphics card is low and it cannot reach 60fps, it will drop to 30fps (1 2 at 60 frames).

If the graphics card performance can't even do 30fps, it will drop to 20fps (1 3 at 60 frames). With VSync enabled, there will be no frames like 50fps or 45fps (because you can't sync with your display unless your monitor has a special refresh rate that is exactly an integer multiple of those frames). The setting method of the positive stove is accurate:

If your graphics card is not performing well (the game FPS is not refreshed at the monitor), it is recommended to turn off this option to keep the game frame rate "as high as possible". If your graphics card is more powerful (the FPS of games can exceed the refresh rate of the monitor), it is recommended to turn on this option to improve the quality of the movie.

The effect of VSync on the number of frames is that VSync limits the frame rate.

Because VSync works by synchronizing the frame rate with the screen refresh rate, when the frame rate is higher than the screen refresh rate, VSync limits the frame rate to the range of the screen refresh rate, resulting in lower frame rates. Because VSync waits for the screen to refresh before the next frame is displayed, it adds a certain amount of latency.

In fact, this delay can affect the experience of the game for some games that require quick reactions. Because VSync needs to wait for the screen to refresh before displaying the next frame, GPU utilization will be reduced while waiting. This will cause the GPU's performance to not be fully utilized, which will affect the smoothness and stability of the game.

The principle of VSync on the number of frames

Vertical synchronization is an important concept in computer graphics processing, and it has a very large impact on the number of frames. Vertical synchronization is when the refresh rate of the display is synchronized with the output frequency of the computer to avoid problems such as tearing and flickering of the picture.

In computer graphics processing, how many frames of images can be output per second is very important. If the output frame rate is too low, the picture will feel stuttered and unsmooth; If the frame rate output is too high, it will waste computing resources and increase power consumption. Therefore, it is very important to control the number of frames.

The monitor's refresh rate is perfectly synchronized with the computer's output frequency. The number of refreshes per second is fixed, usually 60Hz or 75Hz. If the number of frames output by the computer is the same as the refresh rate of the monitor, the stability and smoothness of the picture can be guaranteed.

Vertical sync lock frame will also be enabled at the same time to prevent screen tearing, which requires higher hardware requirements!

Turning on VSync will keep your game frame rate above 60 fps (the LCD default refresh rate), and sometimes it can exceed 60 fps or even higher when you turn it off.

1. Vertical synchronization is also known as field synchronization (vertical hold), from the display principle of CRT display, a single pixel constitutes a horizontal scanning line, and the horizontal scanning line is stacked in the vertical direction to form a complete picture. It is a signal to wait.

2. The feature of V-sync is to prevent frame skipping, which is a good setting, it is recommended to turn it on, usually it is recommended to turn it on.

3. However, if the picture is not smooth, turning off V-Sync can effectively increase the frame rate of the picture.

There are many reasons why your computer becomes slower than your card.

Open the Tencent PC Manager --- toolbox --- hardware detection,See if the graphics card、Memory should be replaced,2、The network speed is too slow,It will also be stuck,You can use Tencent PC Manager to detect。

4.Computer poisoning, occupy a large resource.

5.You can use Tencent PC Manager to carry out antivirus, restart the computer and press F8 to enter safe mode - open Tencent PC Manager - Lightning Antivirus - Full Disk Scan - Complete the restart of the computer.
