Hi all - need some help on this. I have a project that is drawing ~10,000 small tiles into one large bitmap container - it’s a mosaic…

In Flash proper and in FireFox it takes about 20 seconds to complete the drawing.

In Chrome it takes about 1:30 and in IE it takes roughly 3:00 - both too slow to be acceptable to the client - who of course reviewed with IE…

I have Flash set to run at 45 fps - and the images are populated by a Timer - at 2 ms intervals… Maybe 2 ms is too fast? But in my testing 1ms was slower as was 3ms… so I kept at 2. And works fine in FF and Flash…

Anyone have any thoughts?
