您是否曾在 Windows 11/10 PC 上工作或玩游戏时注意到鼠标动作的延迟？这种延迟在技术上称为鼠标延迟(Mouse Latency)。今天让我们多了解一点。在这篇文章中。我们将讨论：
- 什么是鼠标延迟？
- 鼠标延迟的原因是什么？
- 什么是鼠标延迟测试？
- 如何在 Windows 10 上执行鼠标延迟测试？
什么是鼠标延迟？
如上所述，鼠标执行命令所花费的时间称为鼠标延迟，也称为滞后。简单来说，鼠标动作的延迟称为鼠标延迟。
因此，如果您的鼠标操作延迟很大，则您的鼠标延迟很高，如果它快速响应您的所有命令，则延迟很低。工作时可以控制一点延迟，但是当您是游戏玩家时，它可能会让您输掉一场比赛。因此，一个好的游戏的关键是尽可能降低鼠标延迟。使用缓慢且滞后的鼠标工作或玩耍可能会很烦人，并且会花费您的注意力和时间。
想象一下(Imagine)，您正在玩游戏，而您的敌人就在您面前。你射了一颗子弹，但你的鼠标滞后了，砰！你走了。
鼠标延迟的原因
如果您的鼠标滞后并且延迟很高，可能有很多可能的原因。如果您使用的是有线鼠标，原因可能是电线被拉扯、连接松动或某些过时的驱动程序问题；如果您使用的是无线鼠标，问题可能是电池、蓝牙(Bluetooth)信号、驱动程序、BIOS的干扰问题(BIOS Issues)或有故障的鼠标。在某些情况下，显卡也会导致鼠标延迟。
什么是鼠标延迟测试？
鼠标延迟测试基本上是鼠标性能测试。完成此测试是为了检查鼠标操作的延迟或实际完成操作所需的时间。我们知道鼠标延迟有很多可能的原因，因此在进行任何类型的修复之前进行鼠标延迟测试非常重要。
如何在Windows 11/10鼠标延迟(Mouse Latency)测试
有几种在线工具可以在Windows 11/10中执行鼠标延迟测试，您可以在其中检查鼠标是否滞后以及其延迟是低还是高。
1] HTML/JavaScript鼠标输入性能测试
这是一个非常简单的在线工具来测试你的鼠标延迟。该网络工具(This web tool)被认为是准确的延迟测试工具之一。打开网页，只需开始以一致的动作移动鼠标光标，该工具就会比较硬件光标和最后记录的鼠标位置之间的差异。
如果您看到上面的屏幕截图，鼠标光标旁边会出现一个红色框。根据此工具，鼠标光标和红色框之间的距离显示鼠标滞后。这里的红圈代表两帧(two frames)鼠标输入滞后。下图中显示了一个良好测试结果的示例。平均小增量实际上是每个鼠标事件的时间，这里等于 7.90 毫秒。Windows PC 中的最佳延迟率应该在 8 毫秒左右。

2]人体基准
这又是一个测试鼠标延迟的在线工具。这个简单的在线工具可以测量您的反应时间并相应地给出分数。内联之前的工具，使用Human Benchmark，您必须注册才能执行测试。根据Human Benchmark，平均（中位）反应时间为 273 毫秒，如果您获得更高的分数，那是因为您的鼠标滞后。但是，该工具说这里的结果也会受到计算机系统延迟的影响。
要执行此测试，您只需登录并单击主概览中的反应测试。它会显示一个红屏，说，等待绿屏，当你看到绿屏时，你必须立即点击，你会得到实时的结果。
该工具(This tool)建议继续尝试以获得准确的结果。您还可以对两种不同类型的鼠标（有线鼠标和无线鼠标）进行此测试，以比较结果。
阅读(Read)：无光标移动，鼠标光标移动不规律或缓慢(No Cursor movement, Mouse Cursor moves erratically or slowly)。
如果您只是在 PC 上工作，鼠标(Mouse)输入延迟或鼠标延迟可能会变得不明显，但游戏玩家显然会注意到延迟，即使它只有几毫秒。不用担心，如果您的鼠标(your mouse lags or freezes)在 Windows PC 上滞后或冻结，您可以轻松修复它。
如上所述，鼠标滞后的可能原因有很多。使用这些工具来检查你的鼠标速度，看看你的鼠标有多快。另外，如果您有任何喜欢的工具来测试鼠标延迟，请告诉我们。
How to perform Mouse Latency Test in Windows 11/10
Have you ever noticed the delay in your mouse actions while simply working on yoυr Windows 11/10 PC or while playing a game? Τhis delay is technically termed Mouse Latency. Let’s learn a little more about it today. In this post. We will talk about:
- What is mouse latency?
- What are the reasons for mouse latency?
- What is a mouse latency test?
- How to perform a mouse latency test on Windows 10?
What is Mouse Latency?
As mentioned above, the time taken by your mouse to execute your command is termed mouse latency, also known as lagging. To put it in simple words, the delay in mouse actions is called mouse latency.
So if your mouse actions are much delayed, your mouse latency is high and if it quickly reacts to all your commands, the latency is low. A little delay can be managed while working but when you are a gamer, it may make you lose a game. Thus, the key to a has a good game is having the lowest mouse latency possible. Working or playing with a slow and lagging mouse can be annoying and cost you focus and time.
Imagine, you are playing a game and your enemy is right in front of you. You shoot a bullet but your mouse is lagging, and bang! You are gone.
Reasons for Mouse Latency
If your mouse is lagging and the latency is high, there could be many possible reasons. If you are using a wired mouse, the reason probably could be the tugged wires, loose connections, or some outdated driver issue and if you are using a wireless mouse, the issue could be with the batteries, interference in Bluetooth signals, drivers, BIOS Issues or a faulty mouse. In some cases, graphic cards can also cause a mouse lag.
What is a mouse latency test?
A mouse latency test is basically the mouse performance test. This test is done to check the delay in your mouse actions or how much time it is actually taking to complete an action. As we know that there are many possible reasons for mouse latency, it is important to do the mouse latency test before proceeding with any kind of fixes.
How to perform a Mouse Latency test in Windows 11/10
There are several online tools to perform the mouse latency tests in Windows 11/10 wherein you can check if your mouse is lagging or not and if its latency is low or high.
1] HTML/JavaScript mouse input performance tests
This is a very simple online tool to test your mouse latency. This web tool is considered to be one of the accurate latency testing tools. Open the webpage and simply start moving your mouse cursor in a consistent motion and the tool compares the difference between the hardware cursor and the last recorded mouse position.
If you see the screenshot above, there is a red box alongside your mouse cursor. As per this tool, the distance between the mouse cursor and the red box shows the mouse lag. The red circle here represents two frames of the mouse input lag. An example of a good test result is shown below in the image. The average small delta is actually time per mouse events which is here equal to 7.90ms. The best latency rate in a Windows PC should be around 8ms.

2] Human Benchmark
This is again an online tool to test your mouse latency. This simple online tool measures your reaction time and gives the score accordingly. Inline the previous tool, with Human Benchmark you have to signup to perform the tests. As per Human Benchmark, the average (median) reaction time is 273 milliseconds, and if you are getting a higher score, it is because of your mouse lag. However, the tool says that the results here are affected by the latency of your computer system too.
To perform this test, you simply have to log in and click on the reaction test from the main overview. It will show you a red screen saying, wait for green, you have to click immediately when you see the green screen and you will get the results in real-time.
This tool suggests keeping trying in order to get accurate results. You can also do this test on two different types of mouses, a wired and a wireless one to compare the results.
Read: No Cursor movement, Mouse Cursor moves erratically or slowly.
Mouse input lag or the mouse latency can go unnoticeable if you are simply working on your PC, but gamers will obviously notice the lag even if it is of a few miliseconds. Not to worry as you can easily fix it if your mouse lags or freezes on your Windows PC.
As mentioned above, there are many possible reasons for the mouse lag. Use these tools to check your mouse speed and see how quick is your mouse. Also, do let us know if you have any favorite tool to test the mouse latency.
