[CS4] Fullscreen projector with Vista extremely slow

[Dolfan23]

Pretty simple I have a Flash CS4 created projector that I developed on a Windows XP computer that runs exactly like I want it to full screen using "stage.displayState = StageDisplayState.FULL_SCREEN". If I then view that projector on a Vista computer it is extremely slow fading in the background, I'm talking 10 seconds to fade in a background jpg from 0-100 alpha whereas that takes 1 second on the XP computers. I've tried this on multiple XP computers and multiple Vista computers and it's the same result on all.

Now, when I take away "stage.displayState = StageDisplayState.FULL_SCREEN" and then run the projector on Vista it's perfect except for the projector Title Bar and Vista start bar which are unacceptable for this project.

Any thoughts on why this is happening or how I can fix it?

I remember having some similar problems..
Try changing the Hardware Acceleration property under Publish Settings -> Flash...

Thanks for the attempt but trying both "Level 1 - Direct" and "Level 2 - GPU" actually made it worse if that's possible.

Update your video driver.

Thanks but it's not a video driver issue as it happens on every Vista computer I try it on and they have up-to-date drivers since I use them at tradeshows and just updated them and they're all very new.

Edit - it also happens on my Vista computer running at home which isn't new but has updated drivers and it performs exactly the same

I still don't know why it won't work with a Flash CS4 created projector but I went ahead and used SWF Studio to create the projector and it works fine now.
