Flash Movie lags while in fullscreen

Posted on 2007-03-18

I am working on a flash desktop application which requires me to have the flash to appear as full screen when run on the computer.
I compiled my flash into executable(.exe) file with mdm zinc but I realise that the flash animation is lagging a lot when it is shown in full screen.
I then try to display the frame rate on the movie and the movie is actually running at 10fps when full screen and animating. It returns to about 20-25fps when it is not having any movieclips animating while remaining full screen. It is running all well at 30fps when opened with flash player at its original size. I have tried publishing it into flash projector and see it in full screen. The frame rate also decreases and shows the lag while animating.

The animation is not some heavy ones. Just simple masking animations because I still just testing it out.
I have used the bitmap cache but it still the same. Also, I realised that it lags most when there are two motions moving simultaneously...

Why is it so? And is there a workaround for this?

Thanks! :)

This happens because the video card has more pixels to update in fullscreen mode than in normal mode. Unfortunately there aren't any decent work arounds for this other than to get a better video card >.>

if running a flash needs such a good video card then isn't it like kind of weird?

i have figured out how it could be solved! all you need to do is to compile it with DirectX enabled and the lag is reduced very much!
