Yes, you will get hw acceleration. You seem to be identifying blitting with
lack of hardware acceleration. Blit is just an operation, it can be hw
accelerated or not. In this case it will be. In windowed mode
when you copy back-buffer to the screen (whether it's a VolatileImage or
BufferStrategy), at the native level somewhere there's a blit (since you
can't generally do a 'flip' in windowed mode.
Maybe i didn't get this issue right here, because after all that what I already tried and all the different possibilities, I am very confused . .. .
If I would be in fullscreen mode and could use page flipping, that would be an alternative if not my accelerated memory on my graphics card would be so limited (-> 64MB). Page flipping would mean, that I have to allocate twice the size of my image in memory, right? You have to remember, that there are some more backbuffers for our old images that have to be stored in that memory, too.
After exprimentationing and testing the whole day, today, I got to the point that my biggest problem is exactly this limited VRAM memory . . . . .
Especially because it is very frustrating, that the memory is lockked a long time after an image had been disposed (I hoped that VolatileImage.flush() would have helped that problem, but it does not really . . .).
I don't see why you would use any more memory with one
approach vs the other.
Thanks,
Dmitri
