In my experience, PowerMizer is a "feature" that only causes headaches. It's awful that it's not user-configurable.
I just figured out how to trick PowerMizer into thinking that the AC adapter is always plugged in, which FINALLY allows me to get a decent framerate for Compiz.
In my xorg.conf, I just add the following line:
Option "ConnectToAcpid" "false"
This frees my Dell XPS m1730's GeForce 8700M GT SLI cards from being stuck in the lowest performance level, when using battery power.
Unfortunately, Adaptive Clocking is still enabled, and I cannot reliably make my GPUs stay at their highest performance level, without scripting a call to "nvidia-settings -q all" every 25 seconds. This would be fine, were it not for the fact that this causes a framerate hiccup, and worse, xruns in my low-latency professional music software, or, in lay terms, the audio would skip during a music performance, which isn't remotely acceptable.
Furthermore, to get the best performance, I must disable SLI, which is stupid.
I'm using the latest beta drivers, 180.16.
NVIDIA: Please please PLEASE PLEASE fix your drivers so:
One can set the clocking properties directly, without performing goofy hacks
Calling nvidia-settings doesn't cause framerate spikes or audio skippage
The driver behaves correctly in a realtime linux kernel
