Twitch 在 PC 上提供了令人难以置信的流媒体体验，但并不完美。即使您拥有最好的互联网连接，您仍会偶尔遇到阻碍直播和预先录制的视频流畅播放的问题。
因此，如果您不断遇到带有大量持续缓冲的不稳定视频源，那么按照下面的修复列表进行操作应该可以帮助您解决这个问题。
检查服务器状态
如果Twitch刚才运行良好，那么您可能正在处理服务器端的问题。您可以通过前往Twitch 状态(Twitch Status)页面来排除这种情况。如果您注意到视频（观看）(Video (Watching))旁边列出的任何问题，您只能等待Twitch解决问题。
降低质量
如果您尝试以更高分辨率流式传输视频，最终可能会由于网络拥塞和速度限制而导致问题。
尝试将提要的质量降低到亚高清分辨率，例如 480p 或更低。使用视频窗格右下方的齿轮形设置图标，然后选择(Settings )质量(Quality )以更改视频质量。
重启浏览器/应用程序/PC
如果Twitch继续缓冲，最好重新启动浏览器、Twitch应用程序或 PC。在大多数情况下，这应该有助于修复阻止Twitch正常加载视频内容的任何小错误和故障。
检查互联网连接
尝试使用Speedtest.net(Speedtest.net)、TestMy.net或Fast.com等在线服务在您的计算机上运行速度测试。
如果您发现互联网普遍较慢，请先软重置您的 Wi-Fi 路由器(soft-resetting your Wi-Fi router)。如果问题仍然存在，请通过以太网(Ethernet)连接（如果可能）或切换到其他 Wi-Fi 网络。
刷新 DNS(Flush DNS)（域名系统(Domain Name System)）缓存(Cache)
刷新 DNS 缓存可能有助于您的 PC 与(Flushing the DNS cache)Twitch服务器重新建立联系。以下是如何做到这一点：
1. 按Windows + X并选择Windows PowerShell (Admin)。
2. 键入以下命令：
清除-DnsClientCache(Clear-DnsClientCache)
3. 按回车(Enter)。
停止带宽消耗者
如果您有任何其他具有活跃下载的应用程序，则可能会对 Twitch 流式传输视频的能力产生不利影响，而不会遇到缓冲问题。尝试暂停它们。
如果您无法识别过度使用网络的应用程序，您可以使用 PC 上的资源监视器(use the Resource Monitor on your PC)来帮助您。
1. 右键单击任务栏并选择任务管理器(Task Manager)。
2. 选择更多详细信息(More details)，切换到性能(Performance )选项卡，然后选择打开资源监视器(Open Resource Monitor)。
3. 切换到网络(Network )选项卡以按应用查看网络活动。
更改 DNS（域名服务）
如果问题仍然存在，最好为您的 Internet 连接更改DNS（域名服务(Domain Name Service)）服务器。使用流行的DNS服务（Google DNS是一个不错的选择）可能会帮助您的计算机找出用于Twitch流媒体的最佳服务器。
1. 打开开始(Start )菜单并选择设置(Settings )>网络和 Internet(Network & Internet) > Wi-Fi或以太网(Ethernet)。
2.在您的互联网连接下选择属性。(Properties )
3. 选择IP 设置( IP settings)下的编辑(Edit )。
4. 将编辑 IP 设置设置(Edit IP Settings)为手动(Manual )并打开IPv4开关。
5. 在首选 DNS(Preferred DNS)和备用 DNS(Alternate DNS)字段中输入以下内容，然后选择保存(Save)：
8.8.8.8
8.8.4.4
禁用 VPN
VPN（虚拟专用网络(Virtual Private Network)）服务非常适合隐私，但它们在网络性能方面并不是最好的。如果您使用一个，禁用它可能有助于 Twitch 流式传输而无需再次缓冲。
删除浏览器缓存

Twitch Keeps Buffering? 13 Fixes To Stream Smoothly
Twitch offers an inсredible streaming experienсe on the РC, but it isn’t pеrfеct. Even if you havе the best internet connection around, you’ll continue to run into occasional hitches that prevent live broadcasts and pre-recorded videos from playing smоothly.
So if you keep encountering spotty video feeds with loads of constant buffering, working your way through the list of fixes below should help you fix that.
Check Server Status
If Twitch worked fine just a moment ago, you might be dealing with issues on the server side. You can rule that out by heading over to the Twitch Status page. Should you notice any problems listed next to Video (Watching), there’s nothing you can do but wait until Twitch sorts things out.
Lower the Quality
If you’re attempting to stream video at a higher resolution, that may end up causing issues due to network congestion and speed limitations.
Try lowering the quality of the feed to a sub-HD resolution such as 480p or lower. Use the cog-shaped Settings icon to the lower-right of the video pane and select Quality to change video quality.
Restart Browser/App/PC
If Twitch continues to buffer, it’s a good idea to restart your browser, the Twitch app, or your PC. In most cases, that should help fix any minor bugs and glitches preventing Twitch from loading video content normally.
Check Internet Connection
Try running a speed test on your computer using an online service such as Speedtest.net, TestMy.net, or Fast.com.
If you notice slow internet in general, start by soft-resetting your Wi-Fi router. If the issue persists, connect via Ethernet (if possible) or switch to a different Wi-Fi network.
Flush DNS (Domain Name System) Cache
Flushing the DNS cache might help your PC re-establish contact with the Twitch servers. Here’s how to do that:
1. Press Windows + X and select Windows PowerShell (Admin).
2. Type the following command:
Clear-DnsClientCache
3. Press Enter.
Stop Bandwidth-Guzzlers
If you have any other apps with active downloads, that may adversely impact Twitch’s ability to stream video without running into buffering issues. Try pausing them.
Should you have trouble identifying apps with excessive network usage, you can use the Resource Monitor on your PC to help you with that.
1. Right-click the taskbar and select Task Manager.
2. Select More details, switch to the Performance tab, and select Open Resource Monitor.
3. Switch to the Network tab to view network activity by app.
Change DNS (Domain Name Service)
If the issue persists, it’s a good idea to change the DNS (Domain Name Service) servers for your internet connection. Using a popular DNS service—Google DNS is a great choice—might make the difference in helping your computer figure out the best servers for Twitch streaming.
1. Open the Start menu and select Settings > Network & Internet > Wi-Fi or Ethernet.
2. Select Properties under your internet connection.
3. Select Edit under IP settings.
4. Set Edit IP Settings to Manual and turn on the IPv4 switch.
5. Enter the following into the Preferred DNS and Alternate DNS fields and select Save:
8.8.8.8
8.8.4.4
Disable VPN
VPN (Virtual Private Network) services are excellent for privacy, but they aren’t the best at network performance. If you use one, disabling it might help Twitch stream without buffering again.
Delete Browser Cache
If you’re streaming Twitch over a web browser, an obsolete web cache can prevent it from working correctly. Here’s how to delete the browser cache on three popular browsers—Chrome, Firefox, and Edge.
Google Chrome
1. Open the Chrome menu and select Settings.
2. Select Privacy and security.
3. Select Clear browsing data.
4. Set Time range to All time.
5. Select the box next to Cached images and files.

2. Select Privacy, search, and services on the sidebar.
3. Select Choose what to clear under Clear browsing data.
4. Set Time range to All time.
5. Check the box next to Cached images and files and select Clear now.
Disable Browser Extensions
Browser extensions can create conflicts with the Twitch web app and stop it from streaming correctly. Disable all add-ons and check if that resolves the issue.
Google Chrome
Select the Extensions icon to the top-right of the Chrome window and select Manage extensions. Then, turn off all the switches on the screen that follows.
Mozilla Firefox
Open the Firefox menu and choose the Add-ons and Themes option. Then, turn off all switches on the screen that follows.
Microsoft Edge
Open the Edge menu, select Extensions, and turn off the switches next to all active extensions.
Update Browser
Your browser itself may have issues that prevent Twitch from streaming as usual. Try applying any pending updates and see if that helps. Here’s how to do that on Chrome, Firefox, and Edge:
Google Chrome
Open the Chrome menu, point to Help, and select About Google Chrome.
Mozilla Firefox
Open the Firefox menu, point to Help, and select About Firefox.
Microsoft Edge
Open the Edge menu, point to Help and feedback, and select About Microsoft Edge.
Switch to the Twitch App
If you keep experiencing issues with buffering while streaming Twitch on your web browser, switch to using the Twitch app for PC and check if that makes a difference. It’s strikingly similar to Twitch’s web app version, and you can start watching as soon as you sign in with your existing Twitch user credentials.
If you already use the Twitch app, try updating it. To do that, open the Twitch menu (select the three-stacked lines to the top-left of the window), point to Help, and select Check for Updates.

3. Uncheck the box next to Use recommended performance settings. Follow that by unchecking Use hardware acceleration when available.
Microsoft Edge
1. Open the Edge menu and select Settings.
2. Select System on the sidebar.
3. Turn off the switch next to Use hardware acceleration when available and select Restart.
Twitch App
1. Select your profile portrait and choose Settings.
2. Select the General tab.
3. Turn on the switch next to Software Rendering Mode.
Twitch Has Stopped Buffering
The fixes above should’ve helped you fix Twitch’s constant buffering on your PC. If the same problem occurs again, don’t forget to work your way quickly through some of the more straightforward solutions above. Clearing the DNS cache, getting rid of the cached browsing data, or stopping network-intensive programs should almost always help you get Twitch working properly again.
