Nvidia performance level issues (PowerMizer)

Hello there.

I got recently a new laptop and thought, that would be a nice moment to switch from Ubuntu to Arch-Linux.
Everything works better than expected (after a few tweaks of course). Unfortunately this doesn't apply to my:

Nvidia Quadro FX 1800M (1024 MB DDR5, 72 CUDA Cores)

I have the latest proprietary drivers installed ( 260.19.21 / Linux-x86_64 ) and I can play games and 3D hardware acceleration works.
The graphic card supports 3 performance levels (found in nvidia settings -> PowerMizer: 0 [low] - 2 [high]).
However, the powermizer switches only between 0-1, the highest will never be used.
Even if I play warsow with 1920x1080 and other graphic intensive settings, I got ~60 Fps, the game lags a bit but powermizer stuck at level 1.
I tried a lot of different settings in modprobe.conf and xorg.conf.

For example:

Option "RegistryDwords" "PowerMizerEnable=0x0"

or

Option "RegistryDwords" "PowerMizerEnable=0x1; PerfLevelSrc=0x2222; PowerMizerDefault=0x3; PowerMizerDefaultAC=0x1"

Neither works as expected.

Has anybody a similar behavior?

Thanks for your help!

Is there nobody having the same or at least having a clue how to solve that?

Can I do something or is this just a Nvidia driver bug?

You can check the nvnews.net forums, I vaguely recall people there reporting such an issue in the past.
