Another Update: MacBook Pro Software Update 1.1

This week seems to be dedicated to updates, as Apple keeps releasing at least one everyday.
Today, it is dedicated to the MacBook Pro Santa Rosa with "MacBook Pro Software Update 1.1“:

This update provides important bug fixes and improves stability with Motion 2 and Motion 3. It is recommended for all 2.2/2.4GHz MacBook Pro models.
This update requires Mac OS X 10.4.9 or later.
Note
This update replaces MacBook Pro Software Update 1.0

This update is supposed to improve NVidia and OpenGL drivers; however we could test if it fixes problems faced by gamers when playing "Prey" or "XPlane". Do not hesitate to inform us if you can evaluate it.
