Google Chrome is now faster on Windows 10 and Windows 11

Chrome performance update

Browsing the web on Google Chrome for Windows 10 and Windows 11
is now faster than ever thanks to new under the hood

Both Microsoft and Google have been trying to reduce
the priority of background tabs by throttling JavaScript.
So far, the efforts have reduced CPU, GPU and memory usage of
Chromium-based browsers and there is more memory, CPU and GPU
for foreground tabs that you actively use.

As mentioned, Google’s solution has been limited to background
tabs. The company previously didn’t focus on the background
usage of window or windows minimized to the taskbar or moved
offscreen. If occluded windows were treated like background
tabs, Chrome’s performance would be significantly better.

Based on this hypothesis, Google started working on a
project called “Native Window Occlusion” to reduce the
background usage of tabs in occluded windows (not actively
visible to the user).

Google has been working on this project for more than three
years and it addressed compatibility issues with multi-monitor
setups, virtual desktops, etc. As part of the optimization
project, Google ignored minimized windows (not visible to
user), virtual desktop as occluded, etc.

“The occlusion thread tells Windows that it wants to know about
various Windows events. The UI thread tells Windows that it
wants to know when there are major state changes, e.g., the
monitor is powered off, or the user locks the screen,” Google
noted in a blog post.

How Google improved performance of Chrome

Google has been testing the feature for a while and it’s now
available to everyone on Windows.

As per Google, Chrome is now up to 25.8% faster on startup and
it has observed a 3.1% reduction in GPU memory usage. Likewise,
Google reported 20.4% fewer renderer frames and rendered
crashes reduced by 4.5%.

Chrome now saves resources for more important foreground
windows and these changes ultimately contributed to reduced
startup and first-contentful paint.

Google observed a 3.0% improvement in first input delay and
6.7% in first contentful paint and largest contentful paint.

New design features for Chrome on Windows

Google is also working on design improvements for Chrome on
Windows. On Windows 11,
Google has rolled out rounded corners to match Windows 11
aesthetic. And the company is now working on another visual
change for Chrome that will apply Windows accent colour to the

Chrome accent on Windows

Of course, this feature would be optional and users can enable
it by navigating to Windows Settings > Personalization >

You’ll need to click on “show accent colour on following
surfaces” for the changes to take effect. Once done, you will
notice Windows accent colour in various parts of the UI,
including bookmark popup, text selection background, and more.
