Google boosts Chrome browser energy efficiency in a number of scenarios by up to 25%

Recently, Chrome updates have gone quite unnoticed due to the fact that most of the changes concerned the introduction of new APIs for developers, especially for game developers . That is why the latest entries on the official Google blogs were relatively concise. In the new version of Google Chrome 23, which has switched from the Beta update channel to the Stable update channel today, not only “under the hood” corrections (although without them), but also a number of improvements that can be noticed in normal browser operations: video decoding now takes place using hardware acceleration by means of GPU, which will play a positive role on the duration of portable computers, and also added a visual manager of permissions for each site.

Hardware video decoding acceleration

The guys from Google did a great job in this direction, given the fact that the standard for Chrome was decoding video via ffmpeg, which worked without any problems. But Google got confused and started screwing up the capabilities of GpuVideoDecodeAccelerator, despite the fact that Chrome does not work on one system. The result of hard work on adaptation was that, according to Google’s assurances, the consumption of processor resources when watching a video was reduced by 25%. Google tested this video on Lenovo T400 under Windows 7. Naturally, power consumption on different hardware and with different OS can vary greatly, but the innovation itself is very useful.

Site-specific permission manager

Google finally transferred a convenient permission manager for sites from Opera, which for a long time kept me from switching to Chrome, but two years later this functionality was added, and it is cool. Now you can set up specific settings for each site in a convenient window without any tricks, instead of going into settings and suffering with the tedious writing of exceptions. Do not want pictures on a specific site? No problem, two clicks, and the problem is resolved. Similarly with JavaScript scripts, plug-ins, cookies (this was before, but not so convenient), access to a microphone, location, etc. Just click on the page icon in the omnibox, and the manager is ready for battle. It looks like this:

One line under the hood

• Added option Do Not Track . Now you can tell websites you don’t want targeted content. Major European and American sites have learned to understand this headline, but there is no certainty about other sites. The option is disabled by default, but it can be enabled in the advanced settings.
• Implemented subtitle support for HTML5
• Implemented input type = time support
• Adobe Flash 11.5 . Despite the fact that Flash Player switched to a new iteration of the 11. * branch, it didn’t bring any new tasty buns. Most bug fixes
• Vulnerability fix . This time Chrome dispensed with critical vulnerabilities, but 6 with a high degree were found and successfully fixed. Of these six, four were found by non-Google members of the Chromium project, for which they received $ 4,000. Details of vulnerabilities are traditionally kept secret until most users upgrade to Chrome 23.
