Flash Screensaver is a Processor Hog

Hi there. I've created a Flash file that's been turned into a screensaver with a little application called Bitbull. The screensaver is working as it should, but the client is unhappy that it is not a fullscreen image.

My problem is that the graphics are large imported jpegs that fade in and out, and also have shapes and text moving on top of them. So at fullscreen, it is unacceptably choppy.

Is there anything I can do to improve this? I need someone to shed some light on this...what affects CPU usage, etc. I've looked at some other screensavers (I can provide URLs to download if you'd like) that have reasonably smooth motion and I'd like to know how they're achieving this. Does the software you use to create the screensaver affect its performance?

Thank you very much.

Are you resizing your flash movie? post your movie x-size and y-size parameters.

You could increase the frame-rate of your movie file. By default it is at 12fps, which is choppy for large movies.

Bring it to 30fps or more, from the menu: Modify > Movie...

Also bear in mind that most screensaver have been coded, not put together in animation packages.

I've done some screensavers in Flash and very similar ones in Delphi (Visual Pascal, if yuo like).  The Delphi ones are always smoother as it's just an executable.

The Flash projector files are basically the Flash Player (exe) and the Flash File (swf) embedded together.  That's why it's big.  The Flash Player interprets the SWF file as it goes, and that's why it's slow.

You really do need a LOAD of memory and CPU speed to smoothly run a big Flash file as a screen saver.

Sorry, but that's just the way it is.  Imagine your Flash screen saver a few years ago when a 50MHz PC with 32MB RAM was fast!  Heh.

I appreciate your thorough answer. Thanks! I guess I'm going to have to rethink the whole thing...probably by simplifying the graphics because I'm certainly not going to learn Delphi!
