Modified AppleGraphicsPowerManagement.kext for the Nvidia GTS250 1GB card (Device ID: 10de0615).
This will resolve all video stuttering that occurs in mission control and launchpad. It also regulates graphics card temperatures and clock speeds to be what they should. It should give a huge increase in graphics benchmarking too.
Compatible with any MacPro SMBios configuration. Make sure your system shows up as a mac pro in 'about this mac' prior to installation.
Tested in 10.7.2.
