I agree with AlbertoT when he says that the support is excellent.
The JavaScript implementation is very well done, too. You can write your own objects and assign them to meshes easily.
The drawback however is that the scripts are not compiled but interpreted. So you wont be able to write complex scripts without considerable slowdowns.
It seems rather slow but it is just an impression
I got the same impression.
While a Gamestudio project of moderate complexity (to be specific: the RTS game 2662) performed pretty good on a weak computer, all the dx studio applications ran very slow on the very same machine.
