Gabriel,

The quick answer is use both.  The two are not mutually exclusive.

Also, don't worry about CPU usage until you built v1.0 of your project. Then, go back and the performance tools to optimize.

douglas

I am still confused as to whether I should use Core Animation or Quartz 2D.

Basically, the task I would like to do is this:
- draw two images with alpha blending in a window (actually, a screen saver window)
- grow and shrink the images at 30 frames/sec
- use as little CPU as possible!


Could some kind soul please advise me on which framework would be best suited?
I read up all day on Quartz 2D and Core Animation, but I'm still confused.
Which one uses the least amount of CPU for the task?


Example code would also be highly appreciated!

Best regards,
Gabriel.
