When running, it uses about 60% CPU !This could be a bit annoying sometimes, if there are other compute intensive processes running, such as video conversions.
Is there anything I could do to reduce the CPU usage of my screensaver? (Other than reducing the frame rate?)The method that seems to be the most compute intensive one is the following:
[imageRep_ drawInRect: zoomed_frame_ fromRect: NSZeroRect operation: NSCompositeCopy fraction: 1.0];
It gets invoked every frame (in -animateOneFrame, which computes a slightly larger zoomed_frame_ every frame). I analyzed my screen saver with Shark, and it says that this method call costs about 85%.
If it helps, here is the complete source code: http://zach.in.tu-clausthal.de/tmp/ArtSaver.m Any ideas or hints will be highly appreciated. Best regards, Gabriel.
