NVIDIA 的图形驱动程序现在具有一项名为NVIDIA 超低延迟模式^{(NVIDIA Ultra Low Latency mode)}的新功能，该功能适用​​于竞技游戏玩家以及希望在游戏中利用最快输入响应的玩家。NVIDIA 控制面板^{(NVIDIA Control Panel)}中的所有NVIDIA GeForce GPU^{(NVIDIA GeForce GPUs)}都可以使用NVIDIA低延迟模式功能。在这篇文章中，我们将向您展示如何在 Windows 11/10 上启用 NVIDIA 低延迟模式。^{(enable NVIDIA Low Latency Mode)}

在我们直接进入它之前，有一点背景。

根据英伟达；

With “Ultra-Low Latency” mode, frames are submitted into the render queue just before the GPU needs them. This is “just in time frame scheduling,” and it will “further [reduce] latency by up to 33%” over just using the Maximum Pre-Rendered Frames option.

This works with all GPUs. However, it only works with DirectX 9 and DirectX 11 games. In DirectX 12 and Vulkan games, “the game decides when to queue the frame” and the NVIDIA graphics drivers have no control over this.

当您的游戏受GPU限制且帧速率介于 60 到 100 FPS之间时，低延迟模式的影响最大^(Latency)，使您能够在不降低图形保真度的情况下获得高帧速率游戏的响应能力。这意味着如果游戏受CPU限制（受CPU资源而不是GPU限制）或者您的^(GPU)FPS非常高或非常低，启用此设置不会改善您的体验。此外，如果您在游戏中存在输入延迟、鼠标延迟，这通常只是低帧每秒 ( FPS ) 的结果，而此设置无法解决该问题。

启用 NVIDIA 低延迟模式

要在Windows 11/10启用 NIVIDIA 低延迟模式^{(enable NIVIDIA low latency mode)}，请执行以下操作：

您需要最新的 NVIDIA 图形驱动程序才能利用此功能。您可以通过GeForce Experience 应用程序^{(GeForce Experience application)}更新您的显卡驱动程序，或 直接从 NVIDIA 网站下载最新的显卡驱动程序^{(download the latest graphics driver directly from NVIDIA’s website)}。完成后，继续如下：

• 右键单击^{(Right-click)}计算机桌面，然后选择 NVIDIA 控制面板^{(NVIDIA Control Panel)}。
• 在弹出窗口中，单击左侧面板中的管理 3D 设置^{(Manage 3D settings)} 以继续。
• 现在，您需要决定如何启用NVIDIA低延迟模式。
  • 如果要为所有游戏启用它，请选择Global Settings。
  • 如果要为一个或多个特定游戏启用它，请选择 程序设置^{(Program Settings)} 并选择要启用的游戏。
• 然后  在列表中选择低延迟模式。^{(Low Latency Mode)} 在右侧的设置列表中选择 Ultra 。超设置会及时提交帧以供GPU拾取 - 队列中不会有帧设置并等待。
• 接下来，单击应用^(Apply)按钮以保存您的设置。

您现在可以关闭NVIDIA 控制面板^{(NVIDIA Control Panel)}。

注意^(Note)：启用NVIDIA低延迟模式可能会降低您的FPS。此模式默认关闭，这会导致“最大渲染吞吐量”。对于大多数人来说，大多数时候，这是一个更好的选择。但是，对于有竞争力的多人游戏，您会想要获得所有微小的优势——包括更低的延迟。

如果您想禁用NVIDIA低延迟模式并使用NVIDIA显卡驱动程序的默认设置，只需返回页面并单击恢复^(Restore)即可。

提示^(TIP)：如果NVIDIA 低延迟模式未^{(NVIDIA Low Latency Mode is not showing up)}在 Windows 11/10 上显示，这篇文章将为您提供帮助。

就是这样！

How to enable NVIDIA Low Latency Mode on Windows 11/10

NVIDIA’s graphics driver now has a new feature called NVIDIA Ultra Low Latency mode, which is intended for competitive gamers and those who want to leverage the fastest input response in their games. The NVIDIA low latency mode feature would be available for all NVIDIA GeForce GPUs in the NVIDIA Control Panel. In this post, we will show you how to enable NVIDIA Low Latency Mode on Windows 11/10.

Before we jump right into it, a bit of background.

According to NVIDIA;

With “Ultra-Low Latency” mode, frames are submitted into the render queue just before the GPU needs them. This is “just in time frame scheduling,” and it will “further [reduce] latency by up to 33%” over just using the Maximum Pre-Rendered Frames option.

This works with all GPUs. However, it only works with DirectX 9 and DirectX 11 games. In DirectX 12 and Vulkan games, “the game decides when to queue the frame” and the NVIDIA graphics drivers have no control over this.

Low Latency modes have the most impact when your game is GPU bound, and framerates are between 60 and 100 FPS, enabling you to get the responsiveness of high-frame-rate gaming without having to decrease graphical fidelity. This means if a game is CPU bound (that is limited by your CPU resources instead of your GPU) or you have very high or very low FPS, enabling this setting won’t improve your experience. Also, if you have input latency in games, mouse lag,  that’s often simply a result of low frames per second (FPS) and this setting won’t solve that problem.

Enable NVIDIA Low Latency Mode

To enable NIVIDIA low latency mode on Windows 11/10, do the following:

You’ll need the latest NVIDIA graphics driver to take advantage of this feature. You can update your graphics driver through the GeForce Experience application or download the latest graphics driver directly from NVIDIA’s website. Once done, continue as follows:

• Right-click on the desktop of your computer and then choose NVIDIA Control Panel.
• In the pop-up window, click Manage 3D settings from the left panel to continue.
• Now, you need to decide how to enable NVIDIA low latency mode.
  • If you want to enable it for all games, select Global Settings.
  • If you want to enable it for one or more specific games, select Program Settings and choose the game you want to enable.
• Then select Low Latency Mode in the list. Choose Ultra in the setting list on the right. The ultra setting submits the frame just in time for the GPU to pick it up – there will be no frame setting in the queue and waiting.
• Next, click Apply button to save your settings.

You can now close the NVIDIA Control Panel.

Note: Enabling NVIDIA low latency mode will potentially reduce your FPS. This mode is off by default, which leads to “maximum render throughput.” For most people most of the time, that’s a better option. But, for competitive multiplayer gaming, you’ll want all the tiny edges you can get—and that includes lower latency.

If you want to disable the NVIDIA low latency mode and use the NVIDIA graphics driver’s default settings, just return the page and click Restore.

TIP: This post will help you if NVIDIA Low Latency Mode is not showing up on Windows 11/10.

That’s it!
