如果您是 PC 游戏玩家，那么您很可能以前听说过V-Sync，尤其是如果您是那种喜欢修改图形设置等的人。在大多数情况下，用户会在GPU自定义设置中看到(GPU)V-Sync ，但几乎不知道它是什么。
这是因为制造商和游戏开发商通常不会添加解释。因此，就目前而言，很明显，添加V-Sync是为了取悦具有广泛知识的高级计算机用户，而另一边的人则感到困惑。
什么是垂直同步？
考虑到这一点，我们决定解释一下V-Sync是什么以及您是否应该在许多视频游戏中启用它。
好的，所以 V-Sync 代表Vertical Synchronization，其主要目的是帮助摆脱游戏中的屏幕撕裂。
你看，如果你的显卡产生的帧数超过了你的显示器的能力，那么屏幕就会撕裂，在某些情况下，它看起来很糟糕。例如，您的图形卡可以推送 100 帧，但您的计算机显示器最高为 60 帧，那么这可能会导致问题。
至于屏幕撕裂，嗯，这是屏幕的某些部分出现不同步的情况。基本上(Basically)，GPU的移动速度比显示器快。

屏幕撕裂的原始解决方案
今天，有多种方法可以减少或完全消除屏幕撕裂，但您知道V-Sync是最初的解决方案吗？它的工作原理是通过软件限制GPU，以确保它与受影响显示器的刷新率相匹配。
尽管如此，该技术并不完美，这是在撰写本文时它被视为过时的主要原因之一。你看，如果你是那种玩很多快速动作多人视频游戏的玩家，那么V-Sync将是不利的，因为它会导致输入延迟。
不仅如此，有时显示器会在屏幕上留下一小段图像，直到下一个图像准备好。所以在很多情况下，垂直同步(V-Sync)是不可用的。

游戏玩家应该打开还是关闭垂直同步(V-Sync)？
我们不想说不，因为尽管存在许多负面因素，但该技术确实有其好处。如果您有严重的屏幕撕裂，那么无论如何，请继续利用V-Sync提供的一切。
您将在此处看到打开或关闭V-Sync的设置：
- 打开图形控制面板
- 打开管理 3D 设置
- 单击程序设置选项卡
- 定位 指定(Locate Specify)为此程序找到的设置
- 选择程序
- 从其下拉列表中选择 On、Off或您想要的。
请记住，那里有替代品，而且还有很多。它们中的大多数要好得多，但有两个最突出，我们将对它们进行一些说明。

垂直同步的最佳替代品
NVIDIA G-Sync：您可能听说过也可能没有听说过G-Sync。但顾名思义，它是一种与V-Sync类似的技术，它确实有效。英伟达(Nvidia)是第一个将这款产品推向市场的人，因此，他们决定给它定价。
当时，这项技术只能与Nvidia显卡和支持G-Sync的昂贵显示器一起使用。
这里最重要的是它消除了游戏玩家在使用V-Sync时所面临的输入延迟。
AMD FreeSync：AMD(AMD FreeSync:)的人开发了FreeSync以响应G-Sync，通过这样做，他们提供了急需的竞争。AMD最大胆的举措是将产品作为免费服务发布，但与G-Sync类似，该工具仅适用于AMD GPU(AMD GPUs)和支持FreeSync 的(FreeSync)显示器。

What is V-Sync in games? Should I Turn Off or On V-Sync?
If you’re a PC gamer, then chances are you’ve heard of V-Sync before, especially if you’re the type of person who loves to tinker with graphics settings, among other things. In the majority of cases, users will see V-Sync in the GPU customization settings but have little to no idea what it is about.
This is because manufacturers and game developers do not usually add an explanation. So, as it stands, it is clear the addition of V-Sync is done to please advanced computer users with extensive knowledge, while people on the other side are left confused.
What is V-Sync?
With this in mind, we’ve decided to explain what V-Sync is all about and whether or not you should enable it in your many video games.
OK, so V-Sync stands for Vertical Synchronization, and its primary purpose is to help with getting rid of screen tearing in games.
You see, if your graphics card is producing more frames than what your monitor is capable of, then the screen will tear, and in some cases, it looks very bad. For example, your graphics card can push 100 frames, but your computer monitors top out at 60 frames, then this can cause problems.
As for screen tearing, well, it is when some section of the screen appears out of sync. Basically, the GPU is moving faster than the monitor.

The original solution to screen tearing
Today, there are multiple ways to reduce screen tearing or get rid of it entirely, but did you know V-Sync was the original solution? It works by limiting the GPU via software to ensure that it matches the refresh rate of the affected monitor.
Still, the technology is not perfect, which is one of the main reasons why it is viewed as obsolete at the time of writing. You see, if you are the type of player who plays a lot of fast action multiplayer video games, then V-Sync would be a detriment because it causes input lag.
Not only that, but there are times when the monitor will leave an image on the screen for a short time until the next one is ready. So in many situations, V-Sync is just unusable.

Should gamers Turn On or Off V-Sync?
We do not want to say no because, despite the many negatives, the technology does have its benefits. If you have severe screen tearing, then, by all means, go ahead and take advantage of everything V-Sync has to offer.
You will see the settings to turn on or off V-Sync here:
- Open your Graphics Control Panel
- Open Manage 3D settings
- Click on Program Settings tab
- Locate Specify the settings found for this program
- Select the program
- From its drop-down select On, Off or what you want.
Just remember, there are alternatives out there, and quite a few at that. Most of them are much better, but two stand out the most, and we will shed some light on them.

The best alternatives to V-Sync
NVIDIA G-Sync: You may or may not have heard of G-Sync. But as the name suggests, it is a similar technology to V-Sync that actually works. Nvidia was first to market with this product, and as such, they decided to put a price on it.
At the time, it was only possible to use this piece of tech with an Nvidia graphics card and an expensive monitor that supports G-Sync.
The most important thing here is that it eliminates the input lag that gamers faced with V-Sync.
AMD FreeSync: The folks at AMD developed FreeSync in response to G-Sync, and by doing this, they delivered well-needed competition. The boldest move by AMD was to release the product as a free service, but similarly to G-Sync, the tool only works with AMD GPUs, and FreeSync supported monitors.
