That's a myth. If he's tweening one or two things the tweening engine
makes absolutely no difference. The only differences in terms of speed
between tweening engines is how each of they handle a massive number of
property updates on a massive number of objects. So there's absolutely
no problem using Fuse on that case, the problem's somewhere else. A
bottleneck problem isn't solved with a larger bottle.
All I can say about the problem is that it seems to be related to
rendering so yeah, you'll have to look into what you're doing. Use
cacheAsBitmap WHERE appropriate (not in the whole movieclip - it's too
big for that), use scrollRect when possible.
Remember, complex vector rendering is EXPENSIVE. So 4000px x 4000px is
nearly suicidal.

Hi Matt,
Like the analogies :)
What tweening engine are you using?
If its your engine, there is a good speed comparison here:

If so, just change to a different engine, not every car is build to move
boulders ;)

Hi,
so this is a very odd problem, but I'm tweening an extremely large
vector file (about 4000x4000px), using the Fuse tween classes. Its
basically your standard "slide across the surface of a massive object
from point to point" effect, nothing fancy. But I'm having a bear of a
time getting it to animate smoothly. In particular, as it eases into
and out of tweens, I'm getting a weird jittering of the MC, so that it
stutters to a stop, like a car with bad brakes. The tweens themselves
are nothin fancy (see below). It seems like the problem started when I
added _rotation to the the mix. The file is vector, imported from AI.
is anyone familiar with this problem? Any recommendations for handling
this sort of basic (or so I thought) effect?
thanks,

function slideToPos(){
var xPos = posArray[active][0];
var yPos = posArray[active][1];
var rPos = posArray[active][2];
active++;
mainpanel_mc.tween("_x",xPos,2,"easeInOutSine");
mainpanel_mc.tween("_y",yPos,2.5,"easeInOutSine");
mainpanel_mc.tween("_rotation",rPos,2.5,"easeInOutSine",null,"slideToPos2()");
}
