Hello,

I am sure that there is a way to execute the command beamsync -d at the time of startup or login.

For some reason, when you type beamsync -d into terminal, exposť becomes silky smooth and very gorgeous.

thanks,
s

What's beamsync? It's not Apple software, I can't find it on my computer.

Have either you got the developer tools installed? I think it's related to Quartz Debug. I don't have them installed at the moment so I can't check.

You can find the Beam Sync Tools in Quartz Debug - Tools -> Show Beam Sync Tools

Not sure about this command line executable though, never heard of it.

Google pointed me to: http://www.macosxhints.com/article.php?sto...050622224239730 (http://www.macosxhints.com/article.php?story=20050622224239730)

Which points to a command line tool availble from here:

scottgrot: You could automate it using a shell script or automator, but you might as well use the defaults write command listed in the macoxhints.com article's comments.

Sorry for the belated reply, I have been out of range for a week.
Thanks teej. After your post I realised that I should have done another search.

Origanally I saw the "beamsync -d" hint on macosxhints.com

I just did another search on osxhints and came up with this thread.

http://www.macosxhints.com/article.php?sto...&query=beamsync (http://www.macosxhints.com/article.php?story=20050622224239730&query=beamsync)

Scroll down to the article by unagi and he tells you the code to type into terminal.

Cheers,
sg

[Edit]
The thread also explains what beamsync does, and what may happen if it is turned off.

From that thread:

found the defaults to change: use this console cmd:
sudo defaults write /Library/Preferences/com.apple.windowserver Compositor -dict deferredUpdates 0 You can verify this by opening /Library/Preferences/com.apple.windowserver in Property List Editor and expand "Compositor"

Open Quartz Debug and reveal the Beamsync tools. change the setting.

Reopen /Library/Preferences/com.apple.windowserver and expand Compositor to see the new setting.

0 = disable beamsync

1 = Auto beamsync

2 = force beamsync

Certainly makes the frame-rate faster on a G5 with a GeForce 6800.
