<story><title>RenderingNG: An architecture that makes and keeps Chrome fast for the long term</title><url>https://blog.chromium.org/2021/10/renderingng.html</url></story><parent_chain></parent_chain><comment><author>jasode</author><text>&lt;i&gt;&amp;gt;A great way Chrome can render content faster is to take advantage of the multi-core CPUs and advanced GPUs present in today’s devices. Multi-core means we can do multiple kinds of work in parallel. For example, Chrome parallelizes running JavaScript, scrolling a web page, decoding an image or video, &lt;/i&gt;&lt;p&gt;I&amp;#x27;ve noticed that Firefox is not as smooth as Chrome when playing 4k video.  This has been an ongoing issue experienced by many for several years:  &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.google.com&amp;#x2F;search?q=firefox+4k+video+stutters&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.google.com&amp;#x2F;search?q=firefox+4k+video+stutters&lt;/a&gt;&lt;p&gt;I just re-tested this on the latest Firefox 93.0 and while it pegs an entire cpu, the playback performance is still jerky and unusable.  And changing the oft-suggested setting of &lt;i&gt;&amp;quot;gfx.webrender.all = true&amp;quot;&lt;/i&gt; still doesn&amp;#x27;t resolve it.&lt;p&gt;I don&amp;#x27;t know what Chrome is doing differently but 4k playback just works with the default settings.</text></comment>
