FULL_SCREEN, Stage3D and OS/X is very slow?

I've recompiled with Telemetry enabled, and have a few different versions...

1) Normal one

2) This has the code for the wall change disabled

( Colin, we were just changing the colour value of a shader every frame, based on 3 separate bouncing RGB values )

3) Fullscreen, not full-screen interactive, mode - and also wall change disabled

• On older hardware, when you zoom into the photos and pan left or right using the buttons, you can clearly see a lot of dropped frames, even with hardware acceleration enabled.

If you have images loaded, the code when moving between images will auto show either a thumbnail or the original high-res image.  This would be the cause of some dropped frames, but this is separate from the overall slow-down issue that we're seeing.  We get it even if no images are loaded, and if you just look around from the middle of the room.

• Performance is fine if you stay zoomed out and pan around.  You can whip the camera around and you won't see dropped frames.

As above, we're seeing a drop in performance if we stay zoomed out and pan around, in full-screne mode.  In windowed mode, it is very smooth / great performance.

• When I look at the SWF using Scout, I see a really long EnterFrame() loop every time I click the arrow, and a lot of activity right as I change to/from fullscreen.

For the toggle to / from full-screen, the code is pretty straightforward - see below...

private function _onMouseEventClick ( event:MouseEvent ):void

  {

   try

   {

    if ( _this.stage.displayState == StageDisplayState.NORMAL )

    {

     if ( bFullScreenInteractive )

     {

      _this.stage.displayState = StageDisplayState.FULL_SCREEN_INTERACTIVE;

     }

     else

     {

      _this.stage.displayState = StageDisplayState.FULL_SCREEN;

     }

     iconFullScreen.visible = false;

     iconFullScreenRestore.visible = true;

    }

    else

    {

     _this.stage.displayState = StageDisplayState.NORMAL;   

     iconFullScreen.visible = true;

     iconFullScreenRestore.visible = false;

    }

   }

   catch ( e:Error ) { };

  }

}

Hopefully the new links with Telemetry enabled will help narrow down the problem, which is of full-screen mode being a LOT less smooth than windowed mode, even when windowed mode is stretched to be practically the same size as full-screen mode.
