> You seem to be identifying blitting with lack of hardware acceleration.

Well, yes . . . . 
Some time ago I found this site on the net: 
http://java.sun.com/javase/6/webnotes/trouble/TSG-Desktop/html/gcrua.html

There it is said that "Any time you see a MaskBlit or any of the General* 
primitives, it typically means that some of your rendering is going through 
software loops." 
Now, my understanding of all the "behind the scenes" stuff is not that great, 
so I assumed, that every time there is blitting involved, it has something to 
do with software instead of hardware . . . . 

> I don't see why you would use any more memory with one approach vs the other.

I thought, if I have two "pages" between whom I "flip" then I must have twice 
the memory for one graphic in VRAM.
On the other side, I thought that with the backbuffer method I only have one 
image (in my case the volatile type) in VRAM on which I render, and after the 
rendering is finished, I put that on the screen . . . . 

You see, I dig around a lot and maybe there are many wrong thoughts in my mind. 
But all in all you help a lot to bring some things in a straight line. I would 
like to read a lot more about the stuff that happens in the background. I mean 
the stuff that goes beyond the Java2D framework (-> hardware acceleration and 
how it works. . .). can you suggest some literature for me?!?

Up to now, thank you very much for your support! 

Besides that all, I haven't figured out a real solution for the problem this 
thread initially started with, but I am on a good way to reconstruct our old 
fashioned graphics library in order to let it use VolatileImages, too, and the 
performance is getting better every day . . . .
