I am running OSX Lion on a Macbook Pro. Some website suggested I put in a command in the terminal to 'increase my graphics performance' by turning off BeamSync. The command was:
sudo defaults write /Library/Preferences/com.apple.windowserver Compositor -dict deferredUpdates 0
The performance of this Mac is now utterly pathetic. Animations do not run properly and some of them are missing completely. Its like the GFX card has been disabled.
I tried running the command again with a 1, but it did not help. Does the deferredUpdates setting get cached somewhere, or enable something else thats causing the issue?
