Thanks to the new background optimization, the Chrome browser on the Windows 10/11 platform runs faster. With the joint efforts of Google and Microsoft, the two parties have been trying to reduce the priority of background tags by controlling JavaScript. So far, these efforts have reduced the CPU, GPU, and memory usage of Chromium-based browsers, allowing you to use the browser more actively.


As mentioned above, Google’s solution has always been limited to background tabs, but it does not handle background windows accordingly. Now when the Chrome browser window is minimized to the taskbar, moved out of the screen, etc., these windows will also be treated as basic tabs, which obviously helps to improve the performance of the Chrome browser.


Based on this assumption, Google began to study a project called "Native Window Occlusion" to reduce the background usage of labels in occluded windows (which users cannot actively see).


Google has worked on this project for more than three years to solve the compatibility issues of multi-monitor settings, virtual desktops, etc. As part of the optimization project, Google ignored scenes such as minimized windows (not visible to users) and virtual desktops.

Google pointed out in a blog post: "The barrier string tells Windows that it needs to be familiar with different Windows situations. The UI string tells Windows that it needs to know when there is an important state change, for example, the display is over, or the customer locks the screen. "Google has been testing this feature for some time, and it is now open to all Windows users.


According to Google, Chrome’s current startup speed has increased by 25.8% compared to before, and a 3.1% reduction in GPU memory usage has been observed.
