Default Re: 8200 (IGP) based motherboards not suitable for VDPAU?

So some kind of power saving I think.
How do I manage this with the driver?

VDPAU seems not to let the driver change the performance level like opengl does.
You can force the card to run at a higher performance level by adding
options nvidia NVreg_RegistryDwords="PerfLevelSrc=0x2222"
To /etc/modprobe.conf and reboot.

But the fact that it does not change the performance level when required is a driver bug that should be fixed.
