How can I enable the PowerMizer (power saving) options in the GeForce Video Cards?
Use the registry editor. Go to HKEY_LOCAL_MACHINE\Software\NVIDIA Corporation\Global. Make a new key under the global key named NVTweak. (unless it is already there). Beneath the NVTweak key, make a DWORD value in the NVTweak key and name it PowerMizer. Set the value of PowerMizer to 1. If there is a DWORD value named NoPages, then you should rename it to something else (suggested rename to _NoPages so that you can restore the original values if you want). When you reboot, a new hardware options tab will appear in the GeForce advanced menu.
