Here is a Chrome extension that will modify existing pages built with the Google maps API v3 to enable it:<p><a href="https://github.com/broady/ForceWebGL" rel="nofollow">https://github.com/broady/ForceWebGL</a>
It looks like WebGL maps have their own GPU exclusion list, or something. I launched Chrome with --ignore-gpu-blacklist and WebGL maps still refuses to run.<p>Chrome 14, Intel Mobile 4, Ubuntu 11.04
It was news to me that Safari supports WebGL -- the "Enable WebGL" option was sitting up there in the Develop menu all this time when I've been switching to Chrome for WebGL pages.
Works very well on my weak laptop GPU.<p>It actually seems smoother than the regular canvas implementation. Plus there are nice transition effects.<p>Not sure how practical it is though, but I do like the idea of shifting graphics intensive work to the GPU.
