Default Re: vdpau slowness with 260.19.06

I have tried the .29 drivers with my GTS 250 , but problems still exists, sometimes when I run qvdpautest is runs ok , but after awhile it slows down again and then it stays like that.
Changing Powermizer has almost no impact. sometimes adaptive mode even gives me 1 fps more...
Disabling hardware scaling no impact.
Disabling compiz no difference

I get the first time after a new driver install ( qvdpautest 0.5.1):
- H264 DECODING (1920x1080): 44 frames/s
2nd, or sometimes after 3rd run:
- H264 DECODING (1920x1080): 20 frames/s

As a temp resolution , I wanted to check what would happen if I overclock my card (gpu@675 Mhz and memory @1000 Mhz ) a bit:
- gpu clock @ 724 , mem clock @ 1020 :
H264 DECODING (1920x1080): 22 frames/s
- gpu clock @ 740 , mem clock @ 1020 :
H264 DECODING (1920x1080): 36 frames/s

An 16Mhz extra, gives me an extra 14 fps , pretty strange results.
