For starters, Chrome 64 brings support for High Dynamic Range (HDR) video. However, HDR support requires that you run the most recent version of Windows 10 (the Fall Creators Update), have a supported GPU and an HDR-capable monitor. If you meet all the requirements, you'll be able to take advantage of more vibrant colors and enhanced contrast that HDR content can deliver.
Other features in Chrome 64 include a more powerful pop-up blocker, which will help to crush "links to third-party websites disguised as play buttons or other site controls, or transparent overlays on websites that capture all clicks and open new tabs or windows." Google will keep track of websites that peddle in these "abusive experiences" and prevent them from opening new tabs and windows.
Another feature aimed at cutting down on annoyances while browsing the web is the ability to "mute" entire sites that autoplay videos. Now when visiting an offending website that blares you with loud audio or videos, you can simply right click on its tab and hit "Mute Site". It's a simple and effective way to improve the user experience, and we welcome the addition.
Google also says that Chrome 64 includes mitigations against speculative side-channel attack techniques. If that sounds familiar, it is in reference to Spectre, which along with Meltdown has turned the PC community upside down. Google also recommends that users take advantage of the Site Isolation feature that was introduced with Chrome 63 to further safeguard your system from further attacks. Site Isolation, however, can result in a 10 to 20 percent increase in memory usage.
