I have been animating in animate(FLAsh before) for quite a long time..the latest version has jerky animation..its not at all smooth...even a bsica ball animation looks jerky..wonder what did they do to it..
if this goes for long..i will have to stop using it...
Can you say more about how a basic ball bouncing animation was made, and are you using AS3 or HTML5 Canvas?
An example of a problem I'm thinking of is where you are using Canvas, and your bouncing includes a custom ease value. That is one of the most demanding things you can do. The same animation would play fine as AS3, and it would play fine in Canvas if you used a preset ease value.
Do you have a small example file of something that plays poorly now?
