I have encountered a strange condition which produces bad performance with our DisplayObjects. Here is the situation:

  1. We use Stage3D and direct mode for our 3D Flash Web Gaming Project.

  2. We use CS6 to build our GUIs for this project. In (and only in) Internet Explorer, the performance becomes bad when the screen is switched from Flash Fullscreen Mode (not browser full screen) to Normal Screen Mode.

  3. Our Main Game GUI, which is a DisplayObject, has many children.

After several tests, I finally found that the performance does not get bad when the property mouseChildren of Main Game GUI is false or without "direct mode". Given that this situation only happens in Internet Explorer with FlashPlayer's direct mode, is there any way for me to revise my code?

  • Checking for mouse interactions can have a large effect on performance. If it's not necessary, you could try setting `mouseEnabled = false` for every child of your Main Game GUI which doesn't need to be interactive. – David Mear Mar 20 '13 at 04:55
  • Thanks for your respond. But this performance issue only happens on IE with Flash's direct mode, I wonder why other browsers don't have this issue？Is there any one encountered this issue as same as me? – 陳龍進 Mar 21 '13 at 04:24
  • @陳龍進 IE tends to have issues with Flash for reasons unknown. – David Mar 21 '13 at 13:01
