It's much better in FireFox, though still not quite as fast as Flash 9. Huh. :/ Interestingly, all three rendering methods run at under 2 fps on my 1.0 Ghz PowerPC Mac in Safari, Flash Player 10.

The game we're working on at the moment requires about 50 frames for one character at 320xsomething - so pretty big. Damn boss characters. With the 2880 Bitmap data size this is a little restrictive - bring on flash 10 (no size limit). Thanks alot for the heads up tho - i could try it with bit-101's 'BigArseCanvas' http://www.bit-101.com/blog/?p=1199 but that might kill performance a little - might get to some tests :P Spritesheets seems like a great improvement for memory usage.

Initially my own prerender I used for precaching worked the same, but I had to make some new methods that can prerender and render spritesheets instead. The reason for this, is that the bitmapdata object is quite big compared to the actual grid it contains. In my test I found a ratio of about 100:4.6 in favor of spritesheets. I ran into memory problems because of this quite early on and switched to spritesheets instead. More info here: http://board.flashkit.com/board/showthread.php?t=780658 At the moment the game I've initially build this prerender for exceeds the memory limit I used to hit (the total memory usage would be about 24mb before Flash crashed). This makes me think there's some other limit in place having to do with bitmapdata's. This is yet another reason to opt for spritesheets instead. This is not the best way to go about precaching.

Will upload a V2 soon. cheers We will be using the LGPL liscence for our code releases- you can do what you want with it :P

Your implementation is really well-done. What license is your code here under? I’ve attempted similar things before, but simpler, and this is not a well-known technique.
