Some canvas examples are very slow on OSX about three.js

Only people that use MacOS are confused why that one is slow ;) Running Ubuntu 10.10 on a not-so-new MacMini I get 30FPS with that example (I bet it's even faster on Windows). I keep saying that MacOS is the new IE6 :)

I'm curious though, where did you see all that confused people? I don't read many blogs/forums so I may be missing some conversations.

The confused people -- mainly word of mouth; friends that I've shown and randoms on twitter (I imagine more then 3/4 would be OSX users)

I'm trying to get a browser with 2D canvas acceleration working the the examples but they (the browsers) all seem to be broken on OSX ATM.

I assume this is why you're getting much better results on linux and windows.

Nope. Canvas Acceleration hasn't landed on Linux yet (don't know about Windows). OSX problem is something different. You can read the details here http://mrdoob.com/blog/post/705

As per users.. I can only use my website stats (which are quite biased to developers already) and OSX users stand at 1/4 (0.8/4 in fact)...

In IE9 it's so fast it can fool you into believing they already implemented WebGL ;)

They clearly did something very very right about handling bitmaps. I hope other browsers will accept the challenge, this would be a good thing for the whole web.

Indeed. I haven't had a chance to try it native though just watched the Galactic video. Feels like that's how they plan to deal with the lack of WebGL support. I guess it's better than nothing :)

Chrome on Windows has 2d canvas acceleration toggleable in "about:flags" (by default it's off). So far I didn't use it as it was unstable.

So on Windows, Earth demo works ok even without accelerated 2d canvas (in Firefox 4 / Chrome 9 / IE9).

The only one that makes problems is geometry_terrain, but even there it's just in Firefox, other browsers are ok.
