Disable nVidia PowerMizer [static 'Level 1']
Wasn't sure where to put this admins, so if you have to move it, feel free.
For those running 64-bit testing/jessie Debian like me, nVidia driver 319.76, the new deal is, in my situation anyway, navigate (as root) to /etc/X11/xorg.conf.d/, there you will see a file called "20-nvidia.conf" (created during the driver install to block nouveau), add ONLY this line:
to the Device section under this line:
Save the changes. Line it up with the above line or it won't work, It worked for me 
Reboot.
Sample of my "20-nvidia.conf" file now:
If you watch the PowerMizer Settings, it will say "Preferred Mode: Auto" and "Current Mode: Adaptive", that doesn't matter, just leave it because it doesn't budge from "Performance Level: 1", the max level.
