Google released the first Chrome OS updates of 2011 to the Cr-48 today. The new version on the development channel includes Chrome browser version 10.0.634.1. Chrome 10 has (among other new features) WebGL support, which I've been eager to try on the Cr-48. The results, I'm afraid, have been disappointing so far.
If you've seen WebGL, then you've probably seen this demo. You've probably also seen it produce surprising frame rates for browser-based 3D graphics. The hardware in the Cr-48, I suspect, just isn't up to the job. Even with only one fish in the tank, I got a depressing one frame per second. I think one was being generous.
I love this one - just not on the Cr-48. The app isn't just slow, like the aquarium demo, it's unusable. But definitely check it out for yourself if you haven't already. It's very cool.
I am hopeful that WebGL performance on the Cr-48 will improve. Chrome has already done a lot to improve browser performance and I expect that will continue. The Cr-48 will probably never run the next generation of web-based 3D games, but I expect that commercial Chrome OS products will have more powerful hardware.
