GPU accelerating 2D Canvas and enabling 3D content for older GPUs
Today’s Beta release brings 2D Canvas improvements and a software rasterizer to Chrome.
For most Windows and Mac users, we’ve enabled GPU-accelerated rendering of 2D Canvas content, so that canvas-based games and animations run faster and feel smoother. You can go to chrome://gpu to see which features are being accelerated. This is a tricky area to optimize, due to the wide variety of hardware and operating system configurations found in the wild. We’ve made a series of small improvements to the way this acceleration works in the latest release, and we're seeking feedback on it from our Beta users. If you notice performance problems with 2D Canvas graphics content, particularly if you’re a web developer using 2D Canvas on your site, please file a bug.
At the same time, we recognize that many people with older GPUs and graphics drivers have not been able to experience the rich content provided by technologies such as WebGL. Chrome is now able to display 3D content viaSwiftShader, a software rasterizer we licensed from TransGaming, Inc. Although SwiftShader won’t perform as well as a real GPU, it will be an improvement for many of our users on older operating systems such as Windows XP.
SwiftShader automatically kicks in for those users who cannot run content on the GPU. If you want to take a peek at what the performance is like with SwiftShader, you can use the --blacklist-accelerated-compositing and --blacklist-webgl flags, wait a few minutes for the automatic download to complete, and then load the relevant web page.
As always, we appreciate your willingness to try out our creaky Beta software and look forward to your feedback and bug reports.
Speed up Google Chrome by enabling hardware acceleration and pre-rendering
We've spent a lot of time jabbering on and on and on about hardware acceleration in the next generation of Web browsers.
The problem, however, is that no stable browsers have it turned on by default. Unless you're running Firefox 4 beta or Internet Explorer 9 RC, you're probably not enjoying hardware acceleration. Heck, our latest poll shows that almost 50% of Download Squad readers run Chrome, anyway!
Turning hardware acceleration on in Chrome 9, 10 and 11 (stable, beta and canary) is easy, and it can significantly speed up surfing on low-powered devices, like laptops -- or if you're the kind of person who has 30+ tabs open on your desktop PC. We'll show you how to turn on pre-rendering, too, which provides another nice speed boost.
