对于在线游戏，没有任何借口会像“它是滞后”那样为游戏性能下降提供任何借口。该术语通常用于输入键盘命令后(keyboard command)游戏响应时间(game response time)过慢的情况。有时也可以出于其他原因说出它，例如对缺乏技能或帧速率下降不承担个人责任。
最后两个与滞后完全无关。事实上，低帧率与您的计算机有关，与网络问题无关，即高 ping，这是导致延迟的原因。大多数游戏玩家仍然不了解他们抱怨的滞后的实际原因。
这种情况经常发生，甚至定义已被更改以适应，将帧下降称为“本地滞后”，并将这些事件结合起来简单地表示“由于极端网络拥塞或处理能力不足，(network congestion or insufficient processing power)应用程序速度(application speed)显着下降”。
每秒帧数 (FPS) 与 Ping
我想滞后是一个俚语，定义可能会根据使用它的人的想法而改变。但是，要准确了解导致延迟的原因，我们首先需要了解每秒帧数 ( FPS ) 和 ping 之间的差异。
为了帮助您识别和修复(identify and fix computer performance problems)发生的计算机性能问题，您必须了解原因。我们可以先分开讨论什么是fps 和 ping(fps and ping)，然后应用我们学到的知识。这将有助于发现我们的在线游戏(online gaming)会话出现性能问题的原因。
每秒低帧数
每秒低帧数 ( FPS ) 是计算机问题(computer problem)，因此在技术上不应被视为滞后。FPS基本上是衡量游戏在计算机上运行情况的指标。它表示您的计算机可以生成的新图像的数量，以在游戏中创建流畅的图像。
帧数越高，游戏玩法就越流畅。当帧数较低时，屏幕上的图像可能会出现断断续续、生涩或看似断断续续的现象。您的计算机可以生成的最大帧数取决于几件事。
- 您的计算机处理单元 (CPU)(Computer Processing Unit (CPU))、显卡 ( GPU )、随机存取存储器(Random Access Memory)( RAM ) 以及硬盘驱动器的规格。
- 您当前正在玩的游戏中的图形设置。
通常，低FPS(FPS)的原因是屏幕上发生的事情比您的计算机可以生成的要多。这通常发生在需要升级组件的计算机(computer in need of upgraded components)上玩更高级的游戏时。仅仅(Just)因为您的计算机可能会检查游戏最低要求的所有复选框，但这并不意味着游戏会顺利运行。
FPS的显着下降可能是由于您的计算机尝试渲染超出其处理能力。您可以通过升级上述四个组件中的一个（或全部）来避免此问题。它还可以帮助确保在玩游戏时没有其他任何东西在后台运行，这样您的计算机的处理资源就不会被分割。
高延迟
滞后，在其真正的定义中，是网络问题(network problem)的结果。也就是说，高延迟，也称为“ping”，是发送和接收信息之间的延迟。因此，当您的网络与游戏服务器(game server)通信时，服务器“听到”您的计算机请求的时间长度会影响您的 ping。
当游戏服务器(game server)回答您计算机的问题时，也会发生同样的情况。收到该答案所需的时间也会影响您的 ping。两者的完整结果将为您提供一个代表您的 ping的数字。(number meant)在游戏中，您的 ping 以毫秒为单位，因此它可能显示为###ms（# 是您的总数）。
ping 越高，您的游戏时间出现(game time)延迟的可能性就越大。通常，如果您的计算机远离游戏服务器(game server)的位置(s location)，您的 ping 可能会很高。这方面的一个例子是当你住在美国东海岸时，你在(United)韩国(States)玩(South Korea)一个新的东方 mmorpg 。您可以期待高于正常的 ping。
高 Ping 指标
当您的游戏出现严重延迟时，每秒帧数可能仍然很高。玩多人游戏(multiplayer game)时，游戏本身可能看起来很流畅，所有图像都按原样生成。但是，在此期间，屏幕上的玩家可能会出现卡住、原地奔跑或被视为正在四处传送的情况。这不是“游戏破解(game hack)”（尽管它并非完全不可能），而是滞后。
另一个指标是试图在第一人称射击游戏(shooter game)中对某人进行射击，但您每次都不断错过，即使在空白范围内(point blank range)也是如此。这可能是因为您的延迟太高，以至于当您的镜头到达屏幕上的对手时，他们实际上已经移动了他们的角色。您输入的操作似乎需要更长的时间才能在屏幕上发生。
滞后(Lag)峰值也是一个问题。这些与前面在多人游戏(multiplayer game)中讨论的传送事物相吻合。您的延迟可能会遇到一个粗糙的补丁，导致数字飙升，因此现在正常行走看起来好像玩家的角色正在进行时间跳跃(time jump)。
改善你的滞后
您个人可以做的事情并不多来改善您的滞后问题。如果适用，建议将服务器切换到与您当前所在位置物理距离更近的服务器。另一个是坚持只使用以太网连接而不是WiFi。缓慢的互联网可能会在您的滞后问题中发挥作用，因此提高连接速度可能会有所帮助。
希望您现在明白，如果您遇到延迟，那是因为网络问题(network problem)而不是计算机(computer one)问题。计算机性能(Computer performance)问题是另一回事，尽管它们可能经常感觉相似。
低FPS 和延迟(FPS and Lag)似乎有关联
为了进一步复杂化延迟是基于计算机性能的概念，低FPS 和延迟(FPS and lag)有时会同时出现。当您的游戏同时遇到网络响应时间问题(network response time problem)和图像生成问题时，可能会发生这种情况。
一个例子是在线多人在线游戏(online mmorpg)中，当进入一个到处都是其他玩家跑来跑去的大城市时，很有可能同时体验到低帧和高 ping。出现延迟是因为服务器正在努力跟上所有正在发生的事情，而您的计算机正在努力在屏幕上生成所有视觉效果，从而导致FPS低。
这可能会导致游戏玩家感到困惑，因为在这种特殊情况下，低FPS 和延迟(FPS and lag)都有相同的原因 - 比游戏同时在一个地方可以处理的人数更多。这并不意味着它们现在是同一个东西，只是大量的玩家是导致计算机性能下降和网络问题(computer performance and network issues)的原因。
为什么这很重要
了解延迟和低FPS(FPS)之间的区别可以帮助您识别问题并有更好的机会解决问题。有些游戏允许您在玩游戏时显示您当前的FPS和 ping。因此，在游戏延迟的同时，您可以检查您的FPS和 ping 计数器以了解发生了什么变化。这将提示您当前的问题，并在可能的情况下允许您修复它。
根据您当前的 ping 与 FPS 级别，您可以执行的操作：
Normal Ping + Normal FPS
High Ping + Normal FPS
- 可能的服务器滞后(server lag)。查看您服务器上的其他人是否抱怨延迟。
- 没什么好抱怨的？确保(Make)您连接到更本地的服务器（如果适用）。如果故意在您的计算机之外的另一台服务器上，您可能已经为出现延迟做好了准备。
- 检查任务管理器中不应该在后台运行的网络程序。(programs running in the background)如果可以，请关闭它们以释放网络资源，或等待它们完成。
Normal Ping + Low FPS
- 如果屏幕上当前正在发生很多事情，请给您的计算机几秒钟的时间来赶上。
- 也可能(Could)是在后台运行的程序，占用了处理资源。您可以检查任务管理器(task manager)并停止它们以查看性能是否提高。
High Ping + Low FPS
- 可能有很多东西。既是您使用的计算机的问题，也是网络问题(network complication)。可能(May)只是两者的不幸飙升。您可以等着看它是否消退并且值恢复正常，或者执行上面其他部分中说明的“修复”
Online Gaming: Ping vs Frames Per Second (FPS)
When it comes to online gаming, no еxcuse for the deсlinе in gaming performance will bе υsed as much as “It was lag”. Τhe term is often rеserved fоr when the game respоnse time iѕ too ѕlow after entering in a keyboard command. It can sometimeѕ also be uttered for other rеasons ѕuch as not taking personal responsibility for a lack of ѕkill or a drop in framerate.
The last two have absolutely nothing to do with lag. In fact, poor frame rates have everything to do with your computer and not complications with the network, namely high ping, which is what causes lag. Most gamers still have no understanding of the actual cause for the lag that they’re grumbling about.
This happens so often that even the definition has been altered to fit, calling a drop in frames as “local lag” and combining the occurences to simply mean “a noticeable decrease in application speed, due to extreme network congestion or insufficient processing power.”
Frames Per Second (FPS) vs Ping
I suppose with lag being a slang term, the definition is likely to change depending on the whims of the people who use it. However, to get into exactly what causes lag, we’ll first need to understand the differences between frames per second (FPS) and ping.
To help you identify and fix computer performance problems when they occur, you’ll have to understand the cause. We can begin by splitting up and discussing what fps and ping are and then applying what we’ve learned. This will help to discover why our online gaming sessions are having performance issues.
Low Frames Per Second
Low frames per second (FPS) is a computer problem, and therefore is not technically supposed to be considered lag. FPS is basically a measurement of how well your game is running on your computer. It indicates the number of new images that can be generated by your computer to create a smooth flowing image in game.
The higher the number of frames, the smoother the gameplay will be. When frames are low, the images can appear choppy, jerky, or seemingly stutter on screen. The maximum number of frames your computer can generate is determined by a couple of things.
- The specifications of your Computer Processing Unit (CPU), graphics card (GPU), Random Access Memory (RAM), and sometimes the hard drive.
- The graphics settings within the game you’re currently playing.
Typically, the reason for low FPS is that more things are happening on screen than your computer can generate. This most often occurs while playing more advanced games on a computer in need of upgraded components. Just because your computer might check off all the boxes for a game’s minimum requirements, doesn’t mean that the game will run smoothly.
A noticeable drop in FPS is likely due to your computer trying to render more than it can handle. You can avoid this problem by upgrading one (or all) of the four mentioned components above. It can also help to make sure that nothing else is running in the background while gaming so that your computer’s processing resources aren’t being split.
High Latency
Lag, in its true definition, is the result of a network problem. Namely, high latency, also referred to as “ping”, is the delay between information being sent and received. So when your network is talking to the game server, the length of time it takes for the server to “hear” what your computer is asking is factored into your ping.
The same also occurs when the game server answers your computer’s question. The time it takes to receive that answer is also factored into your ping. The complete result of both will provide you with a number meant to represent your ping. In game, your ping is measured in milliseconds so it may show up as ###ms (# being your total).
The higher the ping, the higher the chance of your game time incurring lag. Typically, if your computer is based far away from the game server’s location, your ping is likely to be high. An example of this is playing a new eastern mmorpg based in South Korea while you live on the east coast of the United States. You can expect a higher than normal ping.
High Ping Indicators
Frames per second may still remain high while your game is experiencing heavy lag. When playing a multiplayer game, the game itself may appear smooth, with all images generated as they should be. However, during this time, players on screen may appear stuck, running in place, or seen to be teleporting around. This isn’t a “game hack” (though it’s not totally out of the realm of possibility), it’s lag.
Another indicator is attempting to land shots on someone in a first-person shooter game but you continually miss every time, even while at point blank range. This may be because your latency is so high that, by the time your shot reaches the opponent on your screen, they’ve actually already moved that character on theirs. Actions you’ve input will seemingly take longer to happen on your screen than they should.
Lag spikes are also an issue. These coincide with the teleporting around thing discussed earlier in a multiplayer game. Your latency may hit a rough patch causing the number to spike making it so that normal walking now appears as if player’s characters’ are pulling off a time jump.
Improving Your Lag
There aren’t many things you can personally do to improve your lagging problem. A suggestion would be to switch servers, if applicable, to one that is closer in physical distance to where you’re currently located. Another would be to stick to using only an ethernet connection as opposed to WiFi. Slow internet can play a part in your lagging woes so increasing the speed of your connection could help.
Hopefully, you now understand that if you’re experiencing lag, it’s because of a network problem and not a computer one. Computer performance issues are a separate thing even though they may often times feel similar.
Low FPS and Lag Can Appear To Be Linked
To further complicate the notion that lag is computer performance-based, low FPS and lag can sometimes show up at the same time. This can occur when your game is experiencing both a network response time problem and an image generating issue.
An example would be in an online mmorpg, when entering a large city filled with other players running around, it’s very possible to experience both low frames and high ping simultaneously. The lag occurs because the server is struggling to keep up with all that’s going on at once, while your computer is struggling to generate all the visuals on screen resulting in the low FPS.
This may lead to confusion amongst gamers as in this particular case, both low FPS and lag have the same cause – more people than the game can handle in one place at the same time. This does not mean that they are now the same thing, just that the large number of players is what is causing both the dip in computer performance and network issues.
Why This Is Important
Understanding the difference between lag and low FPS can help you to identify problems and have a better chance at fixing them. Some games will allow you to display your current FPS and ping while playing. So, while suffering lag in game, you can check your FPS and ping counters to see what has changed. This will tip you off to the current problem and, if possible, allow you to fix it.
Things you can do based on your current level of ping vs FPS:
Normal Ping + Normal FPS
High Ping + Normal FPS
- Possible server lag. Look to see if others on your server are complaining of lag.
- No complaints? Make sure your connected to a more local server (if applicable). If purposefully on a further server from your computer, you’ve likely already braced yourself for lag occurrences.
- Check task manager for networking programs running in the background that shouldn’t be. Close them if you can to free up network resources, or wait for them to finish.
Normal Ping + Low FPS
- If a lot of things are currently happening on screen, give your computer a few seconds to catch up.
- Could also be programs running in the background, eating up processing resources. You can check task manager and stop them to see if performance increases.
High Ping + Low FPS
- Could be many things. Both an issue with the computer you’re on as well as a network complication. May just be an unlucky spike in both. You could wait to see if it subsides and the values return to normal, or perform the “fixes” illustrated in the other sections above
