your typical HD h264 content is from a bluray, which is 24 pic/s ; your card can do twice that.
Here is 100% of the HD content I watch:

DishNetwork satellite H.264/AVC

OK, so satellite is 29.970 interlaced, fair enough my decoder can handle that. But ATSC is 59.970 progressive, and the decoder is rated at 62 pic/s. However this is at 1080 and my sample is 720. I guess this is OK.

I've just updated my nVidia driver from 185.18.10 to 185.18.14 and here are the results:

Quadro 1600M (HP 8710w laptop):
Code:
SURFACE GET BITS: 528.471 M/s
SURFACE PUT BITS: 474.799 M/s

MPEG DECODING (1920x1080): 60 pic/s
H264 DECODING (1920x1080): 43 pic/s
VC1 DECODING (1440x1080): 83 pic/s

MIXER WEAVE (1920x1080): 891 frames/s
MIXER BOB (1920x1080): 1304 fields/s
MIXER TEMPORAL (1920x1080): 286 fields/s
MIXER TEMPORAL_SPATIAL (1920x1080): 90 fields/s
9300 IGP (Asus P5N7A-VM mobo)
Code:
SURFACE GET BITS: 984.095 M/s
SURFACE PUT BITS: 1112.54 M/s

MPEG DECODING (1920x1080): 60 pic/s
H264 DECODING (1920x1080): 53 pic/s
VC1 DECODING (1440x1080): 67 pic/s

MIXER WEAVE (1920x1080): 297 frames/s
MIXER BOB (1920x1080): 451 fields/s
MIXER TEMPORAL (1920x1080): 109 fields/s
MIXER TEMPORAL_SPATIAL (1920x1080): 33 fields/s
I am surprised to find that the 9300 performs worse than the 1600M. It is supposed to be so much better.

And I am not clear on how to apply these findings to whether these deinterlacers are fast enough for Advanced2X?

And disturbingly, when I close the final window for qvdpautest on my 9300 system, it locks up the machine entirely. I have to power down and up, to get it back.
