Force Nvidia Powermizer to stay at highest performance setting

If you're running drivers above version 185, then this guide is likely obsolete, as Powermizer has had a preferences option in nvidia-settings since then.

This is a nice quick one. To force Powermizer to stay at the default (and highest) clock of your graphics card always upon boot:

sudo gedit /etc/modprobe.d/options
Add the following line to the file:

options nvidia NVreg_RegistryDwords="PerfLevelSrc=0x2222"

Save and exit, then reboot.

Other performance levels may be specified, replace 0x2222 with 0x2233 for adaptive clocking.

UPDATE: This method does not appear to work for me in the latest versions of Ubuntu, please try the method in this post.
