Thanks for the links to details. Which of those videos is a real game? I clicked through them and only saw one game demo and the speaker explicitly said it's 'just one car', so that's probably not the one you're referring to. Is there a specific video I should look at?

This one:

I apologise for the darkness of the recording of the Quake 4 demo, we did another presentation at Develop - Evolve this morning that will show the demo in all its glory.

Thanks for the link. The Score Rush and Space Ark demos represent you much better, especially since they are by third-party developers (despite the poor video quality). Were they both running in pure WebGL under Chrome, or did they rely on your native plugin? I was unable to find any documentation on your site that actually explained what specific features require the plugin.

Everything run in pure WebGL. The sound used Web Audio (but we also support HTML5 Audio).

We do not demo anything running with the plugin any more.

Lack of WebGL support is the only reason to use the plugin. Now we also have a pure JavaScript 3D physics and collision solution (to be available on the next SDK release).
