Google Chrome 18 brings two methods of improved graphics support to both newer and older computers. Released today, Google Chrome 18 stable for Windows (download), Mac (download), Linux (download), and Chrome Frame improves both WebGL and Canvas2D.
To help along WebGL in Chrome on older Windows and Mac computers, it now gets a boost from a software rasterizer called SwiftShader, licensed from TransGaming. SwiftShader only works when Chrome's baked-in graphics processor acceleration doesn't run, and in the blog post announcing the update, Google said that it sought out this third-party solution so that "more users will have access to basic 3D content on the web."
The Canvas2D changes will allow the same older PCs to process game and animation graphics faster. When Google originally debuted the improved Canvas2D in Chrome beta, the company noted that the multitude of older hardware configurations caused significant delays in implementing the improvements. The feature doesn't yet work for Linux.
In the offing for Chrome 19, due around six weeks from today, and Chrome 20, due just before June's Google I/O conference, are full implementation of Google's Native Client (NaCl) tech. Already partially available in the Chrome 19 developer's version, NaCl and its API set known as Pepper will allow, the company says, gaming support in the browser that will come close to console-quality graphics.
Chrome 18 also updates the Adobe Flash plug-in to its latest version, and makes numerous security and bug fixes. There were no "critical" security fixes, but there were a few "high"-level fixes, out of nine security fixes reported.
