YouTube Videos are lagging on PC ? Try this fix!
Your graphics adapter or card may not support decoding VP9 or VP8 encoded videos. You tried enabling or disabling Hardware Acceleration, but still no fix. We know. Because some graphics cards do not come with inbuilt VP9 or VP8 decoder, so your CPU has to do that inefficiently with major stuttering and lags.
What should you do?
VP9 is relatively newer codec, and open source. YouTube has implemented this because it saves lot of bandwidth and storage space because it compresses video files more efficiently. You can’t just enable HW acceleration for this, but you’re the BOSS right?
Without talking any further lets get to the point. You have to install a Chrome or Firefox extension named “h264ify”.
For Google Chrome, Open Chrome web Store search for h264ify.
Install this extension on your browser. It basically tells YouTube that your browser doesn’t support VP9 codecs so it falls back to H264 codec, and guess what! Even crap Graphics Cards also support HW acceleration on H264 encoded videos.
Limitation: You wouldn’t be able to watch 4K on YouTube, because 4K only comes VP9 encoded.
For Firefox follow the same on addons.mozilla.org .
