Interesting. Can you please name the framework you left behind? Also, why did it seem to be more time-efficient to ditch canvas altogether and rewire the rende

  I'd also like to know more, I have just been rolling my own stuff so far and have been surprised by how well the canvas is handling everything I throw at it. Tablets / Phones is a little different, but the desktop much faster than I expected.

  That was OCanvas (ocanvas.org). It's perfectly fine for vector stuff, but our game is very bitmap heavy. We started getting FPS rates as low as 10 with only 5-10 characters on screen (using animated/scaled Sprite objects). Using DOM + transforms we can get up to 500 chars on screen without any lag whatsoever. We didn't ditch canvas altogether though, we render all the scenes in a background canvas and use DOM only for the moving chars. I suspect it's possible to get much better performance by pre-rendering all scaled objects, but haven't had the time to try it. CAAT performs incredibly well with bitmaps on canvas: http://labs.hyperandroid.com/static/caat/ http://labs.hyperandroid.com/static/caat/
