Default Re: GF100 VDPAU performance is really not good

I confirm that the bug appeared in 256.x version of the driver. The 195.36.24 can perfectly go to performance level 2 and we can see the difference in the "mixer" tests of qvdpautest...

GLXGEARS is around 4000 fps with the 195.x and around 3000 fps with 256.x and following drivers, which is logical as we are stuck at performance level 1.

Nvidia, please fix this powermizer issue... It has been 1 year now since the regression...
