Default Nvidia performance level issues (PowerMizer)

Hello there.

This is my graphic card:
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 ~90-124 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:
Code:
Option "RegistryDwords" "PowerMizerEnable=0x0"
or
Code:
Option "RegistryDwords" "PowerMizerEnable=0x1; PerfLevelSrc=0x2222; PowerMizerDefault=0x3; PowerMizerDefaultAC=0x1"
Neither works as expected. I can't switch to performance level 2. :/

Has anybody a similar behavior?
I searched a lot but found nothing which could help me.

Thanks for your help!
