Streaming issues

<p>If it's a lower-end device, it is likely the "Widevine" encryption causing high CPU: the vast majority of YouTube videos won't use any encryption, so you won't find an issue there. In Google Chrome or Microsoft Edge, while playing such a video, right-click the top-bar (where the tabs are, but not on a tab) and choose "Browser task manager". Check in there how much CPU the "Utility: Widevine Content Decryption Module" shows as.</p><p><br></p><p>Make sure that you are running on "best performance" level: click the battery icon on the Windows taskbar, and make sure the slider is towards the right; at the left, your device's CPU is ran slower. Also check "battery saver" mode is off.</p><p><br></p><p>On a lower-spec device, it may also help to go to Start &gt; Settings &gt; Apps &gt; Video Playback and tick "I prefer video to play at a lower resolution", as this will cause less CPU stress. (I think this setting only affects videos inside apps you get from the Windows Store).</p><p><br></p><p>Also check in your browser that "Hardware Acceleration" is turned on: in Edge, go to … &gt; Settings &gt; System. Same in Google Chrome, though click "Advanced" when in the settings to expand the list. In Firefox, go to "hamburger menu" &gt; Options &gt; General &gt; scroll-down to Performance and make adjustments there.</p><p><br></p><p>Beyond that, try checking if an update for your graphics-card driver is available.</p>
