Sorry guys I am not sure I am right but I can't see any awesome performance here.In my browser Firefox 4 it runs around 25-30 fps when I start firing the balls. Also would like to note that Alchemy bridge is not always faster contrary to what people may think.I made a benchmark of square root algorithms calculations in Flash a couple of months ago.You can read about it here: http://blog.alladvanced.net/2011/02/21/square-root-calculation-speed-in-flash-and-unity3d/.So basically I tried the built in Math.sqrt ,Fast Inverse square root algorithm developed by ID for quake (in AS) and the same Fast Inverse Square root but in C in Alchemy .To my great surprise the result was that the alchemy version was the slowest.Several times slower than the Native Flash implementation. BTW the fastest was HaXE implementation of the FISR Would be happy to hear some thought on this Michael.
