We have to inject some properties in the device tree. The  Chameleon v2  bootloader does that automatically for many cards, you just have to enable the  GraphicsEnabler  option and configure the  PciRoot  (only if it's not zero). In the file  com.apple.Boot.plist         <key> GraphicsEnabler </key>         <string> y </string>         <key> PciRoot </key>         <string> 1 </string> You can use the app  Lizard  ( LINK ). Check the  Graphics Injection  option, click on  Auto-detect value  in  PCIRoot  and  save . In Lizard preferences, configure the  Extra folder Path . Select the Extra folder in the partition where you installed Chameleon. There are kexts for that (NVenabler, NVinject, EvoEnabler, among others) but they do exactly the same thing, inject properties, they are n...

>>> DOWNLOAD nVidia Injection <<< First about  display-cfg . It describes what type of screen is attached. The last two bytes are made up as following: If some condition (unknown yet, we thought it had to do with if a screen is attached to that output, which it had not) is met we get: BYTE : Display - Number BYTE : I2C Read Offset BYTE : 0xFF BYTE : 0xFF If the unknown condition above is not met its build up as following regarding the type of screen attached. For ANALOG: BYTE : Display - Number BYTE : I2C Read Offset BYTE : 0xFF BYTE : 0x00 For TV: BYTE : Display - Number BYTE : I2C Read Offset BYTE : 0xFF BYTE : 0x01 And for everything else like LVDS, TMDS and Display-Port BYTE : Display - Number BYTE : I2C Read Offset BYTE : DCB Entry OR ( guessing ) BYTE : 0x03 There is one display-cfg for each screen. Here an example (note we have to swap bytes to inject): ANALOG @ 0 , display - cfg < 00FFXX00 >  XX = I2C Read Offset @ 1 , d...

We wrote a long explanation why and how to edit these thresholds. You may want to read all of this or just copy and paste these values to your AppleGraphicsPowerManagement.kext and change to your vendor device. I might add, these values are not written into stone. I have used the power efficiency thresholds for a week and I am very happy with them. You however, might find thresholds that works better for your everyday usage. I encourage to edit these values and run tests on them. I added a high performance mode as well, to show the difference. Power efficiency thresholds: (focused to stay in G-state 2 during everyday usage and therefore saves up to 55W~110W) Threshold_High 0 45 75 100 Threshold_Low 0 0 87 98 <key> MacPro5,1 </key>                                   <dict>                                 ...

Upgrade from previous versions:  - You can upgrade your existing Lion (I0.7.x) and Mountain Lion (10.8.x) installations to Mountain Lion 10.8.2 or make a refresh install to your 10.8.2 system (keeping your applications, user accounts, user settings and user data) by using iATKOS ML2 . To upgrade from Snow Leopard (10.6.x), you should first upgrade to Lion (10.7.x) by using iATKOS L, #Niresh Lion, or any other methods.  - I advice you to do a clean install to another HDD on your computer before upgrade, to see that it actually works on your computer.  - You will need to re-install your special device drivers after upgrade. i.e. your m-audio firewire sound driver, your 3G modem driver, your All video card driver. - Some of your applications that runs on the previous versions of OS X may not be compatible with Mountain lion 10.8.2, so know that they may fail after upgrade. Search for your existing software/driver compatibility for Mountain Lion before upgrading to Mountain ...
