Is 80000 particles the limit? With Flash you could render +300000 particles years ago: http://www.unitzeroone.com/labs/alchemyPushingPixels/

That demo gets about 19 fps on my machine, whereas the WebGL demo appears to be getting close to 60, so that seems to be scaling pretty similarly. Also keep in mind that the demo you linked to uses Alchemy, which is C/C++ compiled to AVM2, so for WebGL to be getting roughly equivalent performance is pretty damned impressive.

I get a dialog box : "There's no WebGL context available.". :\

Using Google Chrome 19.something on Ubuntu, with open source radeon driver.

It looks very impressive. I'd love to see some kind of game using particles like that, something like Osmos:

I used particles pretty heavily in my (inneficient) WebGL game Up and Above: http://littlesquareblock.com/upandabove

It's not nearly as efficient as this demo, but it's at least a game. There are at least a dozen areas I could fix up to prevent the GC from going nuts if I was so inclined, but it works fine for most people.

Chrome 18, nVidia GTX260M, on Windows with official binaries.

Same error.

This is awesome. Also like his Lego survey stats app http://minimal.be/lab/legoStats/

Pretty neat game. WebGL is still a little clunky on Linux but I was still getting a playable framerate (but just barely).

That's good to know. We get really bad performance on linux because of the AA I think.

Thanks for taking literally 10 minutes of my time ... pretty badass, am always mesmerized by particles :)

Also look that the stage (canvas) size for the demo (this used to make a big difference in older versions of the player at least).
