如果 PC 游戏玩家似乎都同意一件事，那就是了解您的FPS（每秒帧数(frames per second)）很重要。这是发烧友衡量硬件和优化性能的方式，它实际上可以让你在竞技射击游戏的竞争中占得先机。
每秒显示帧数的选项有很多，但许多选项非常密集，实际上会降低系统的性能。好消息是Steam有一个内置的FPS计数器，您可以在玩Steam 游戏(Steam games)时显示该计数器。这是设置和查看它的方法。
如何显示 Steam 的内置 FPS 计数器(Built-In FPS Counter)
访问 Steam 的内置FPS计数器很简单。当您不在游戏中时，前往Steam >设置( Settings )并从左侧菜单中选择游戏内。(In-Game)屏幕中间是选项列表。选择游戏内 FPS 计数器(In-game FPS counter)并单击下拉框。
默认情况下，它设置为“关闭”。您可以选择计数器出现的四个位置之一：左上角、右上角、左下角、右下角。选择位置后，单击“确定(Okay)”并启动游戏。当你这样做时，你的帧率应该会出现。
您可以使用另一种选择。在下拉框下方，单击高对比度颜色。(High Contrast Color.)无论游戏中的背景颜色如何，这将使数字很容易看到。如果您不启用此功能，数字将显示为白色，并且在天空或云层下难以看到。
理想目标帧率
人眼每秒可以翻译大约 30 帧，但它可以区分(distinguish differences in rates)除此之外的速率差异。在游戏方面，任何低于 30 帧的内容都被视为低于标准。低于每秒 24 帧，图像将不再看起来连贯，反而会显得断断续续和被抛弃。
每秒 30 帧被认为是您应该瞄准的最低限度。对于单人游戏来说，这是一个完全可以接受的数字，尽管更高的计数可以使它更具电影感。
当您玩多人游戏时，每秒 60 帧是您应该达到的最低速度。这么多帧将为您提供更流畅的体验，并且被认为是大多数游戏机性能的“目标”。
然而，最高端的机器在某些游戏上可以达到每秒 300 帧甚至更高。每秒生成的帧越多，屏幕上的动画就越流畅。测试表明，高帧率可以转化为射击游戏的更好瞄准，也非常适合在那些竞技游戏中做得更好。
如何处理较低的帧速率
如果您启用内置Steam FPS计数器并在您最喜欢的游戏上看到低于 30 的速率，则可能有几个不同的罪魁祸首。识别(Identifying)并消除或升级这些可能性将提高您的表现。
首先要看的是游戏的推荐和最低规格。确保(Make)您的计算机具有至少满足最低建议的适当组件。如果没有，您将看到低于标准的性能。如果您不符合建议，最好的选择是升级计算机的组件(upgrade the components of your computer)。
在很多情况下，帧率会受到显卡质量的(quality of your graphics card)影响。如果您使用的是较旧的GPU，则需要升级到更新、更现代的选项。GTX 1650是一个不错的、经济实惠的选择。如果你想瞄准顶级产品，比如新的RTX 3000系列，祝你好运——供应有限，这导致这些卡的成本显着提高。
如果您升级GPU，您可能还需要升级主板和电源以解决更大的功耗问题，因此请记住这一点。在GPU之外，您还应该考虑您的CPU是否需要升级。
为什么您的帧速率低于预期的最后一种可能性是优化。无论他们的系统多么强大，有些人都会因为游戏而体验到较低的帧数。以Microsoft Flight Simulator为例：它在所有计算机上都非常密集，而且很少（如果有的话）游戏玩家能够获得完美的帧速率。
替代帧计数器
如果您不想使用Steam的FPS计数器（或者您需要计算不在(FPS)Steam上的游戏的每秒帧数），还有其他选择。
FRAPS可能是当今最受欢迎的FPS计数器。它已经存在了很长时间，并且与Windows广泛兼容。FRAPS完全免费下载和使用，并且有大量的自定义选项。
您可以选择在屏幕的哪个角落显示计数器，选择更新计数器的频率等等。这是跟踪帧速率的最佳选择之一。
如果您使用Nvidia显卡，您可以利用GeForce Experience软件来显示您的每秒帧数——但请注意，使用AMD显卡的人无法使用它。
不过， GeForce Experience(GeForce Experience)不仅仅是一个帧计数器。它使您可以完全访问显卡的设置，并允许您自定义显卡以满足您的需求和所需的性能。
FPS Monitor是另一个用于跟踪帧的免费选项，但该实用程序并不止于此。FPS Monitor可以显示与您的系统性能相关的许多其他信息，包括RAM和CPU使用率、HDD速度等。
您还可以自定义叠加层以更改其在屏幕上的显示方式。这在调整计算机性能时特别有用，因为FPS Monitor会在硬件接近临界点时提醒您。
无论您是铁杆游戏玩家还是性能爱好者，了解如何使用 FPS 计数器来优化您的计算机并改善您的游戏体验都很重要。使用这些计数器之一来查看您的计算机在您最喜欢的游戏中的实际表现。
How to Display Steam’s Built-In FPS Counter
If there’s one thing PC gamers all seem to agreе on, it’s that knowing your FPS (frames per second) matters. It’s how enthusiasts measure the performance of their hardware and optimization, and it can actually give you a leg up on the competition in competitive shooters.
There are a lot of options for displaying frames per second, but many are so intensive that they can actually decrease your system’s performance. The good news is that Steam has a built-in FPS counter that you can display whenever you play Steam games. Here’s how to set that up and see it.
How to Display Steam’s Built-In FPS Counter
Accessing Steam’s built-in FPS counter is simple. When you aren’t in a game, go to Steam > Settings and select In-Game from the left-hand menu. In the middle of the screen is a list of options. Choose In-game FPS counter and click the drop-down box.
By default, it’s set to “Off.” You can choose one of four positions for the counter to appear: top-left, top-right, bottom-left, bottom-right. After you choose the position, click Okay and launch a game. Your frame rate should appear when you do.
Another option is available to you. Beneath the drop-down box, click High Contrast Color. This will make the number easily visible no matter the background color in a game. If you don’t enable this feature, the number will display as white and be difficult to see against the sky or clouds.
Ideal Target Framerate
The human eye can translate roughly 30 frames per second, but it can distinguish differences in rates beyond that. When it comes to gaming, anything lower than 30 frames is considered sub-par. Below 24 frames per second, the image will no longer look cohesive, but will instead appear stuttery and jilted.
30 frames per second is considered the bare minimum you should aim for. This is a perfectly acceptable number for single player games, although higher counts can make it more cinematic.
When you play multiplayer, 60 frames per second is the lowest you should go. That many frames will give you a smoother experience and is considered the “target” for performance on most gaming machines.
However, the highest-end machines can hit 300 frames per second and higher on certain games. The more frames generated per second, the smoother the animations on screen. Tests have shown that high framerates translate to better aiming in shooters, too–perfect for doing better in those competitive games.
How to Handle Lower Frame Rates
If you enable the built-in Steam FPS counter and see rates lower than 30 on your favorite games, there are a few different culprits that might be responsible. Identifying and eliminating or upgrading these possibilities will improve your performance.
The first thing to look at are the recommended and minimum specs of a game. Make sure your computer has the proper components to at least meet the minimum recommendations. If not, you will see sub-par performance. If you don’t meet the recommendations, your best option is to upgrade the components of your computer.
In many cases, frame rate is affected by the quality of your graphics card. If you’re using an older GPU, you’ll want to upgrade to a newer, more modern option. A good, budget-friendly choice is the GTX 1650. If you want to aim for top-of-the-line, such as the new RTX 3000 series, good luck–supply has been limited, which has driven the cost of these cards significantly higher.
If you upgrade your GPU, you might also have to upgrade your motherboard and power supply to account for the greater power draw, so keep that in mind. Outside of the GPU, you should also consider whether your CPU needs an upgrade.
The final possibility for why your frame rates are lower than expected is optimization. Some people experience lower frames due to the game, no matter how powerful their system is. Take Microsoft Flight Simulator, for instance: It’s intensive on all computers, and very few (if any) gamers are getting perfect frame rates.
Alternative Frame Counters
If you don’t want to use Steam’s FPS counter (or you need to count the frames per second of a game that isn’t on Steam), there are alternative options.
FRAPS is perhaps the most popular FPS counter available today. It’s been around for a long time and is broadly compatible with Windows. FRAPS is completely free to download and use, and has a huge number of customization options.
You can choose which corner of the screen to display the counter in, choose the frequency with which the counter is updated, and much more. This is one of the best options for keeping track of your frame rate.
If you use an Nvidia graphics card, you can take advantage of the GeForce Experience software to display your frames per second–but note that it isn’t available to people with AMD graphics cards.
GeForce Experience is more than just a frame counter, though. It gives you full access to your graphics card’s settings and allows you to customize the card to fit your needs and desired performance.
FPS Monitor is another free option for tracking your frames, but the utility doesn’t stop there. FPS Monitor can display a host of other information related to your system performance, including RAM and CPU usage, HDD speed, and more.
You can also customize the overlay to change the way it appears on-screen. This can be particularly useful when tweaking your computer’s performance, as FPS Monitor alerts you if hardware is approaching a critical point.
Whether you’re a hardcore gamer or a performance enthusiast, understanding how FPS counters can be used to optimize your computer and improve your gaming experience is important. Use one of these counters to see how your computer actually performs during your favorite games.
