Hi,

I have a h.264 clip but it makes my AMD X2 4400+ goto 100% so obviously the hardware acceleration isn't working, I'm using Purevideo 1.02-223 (Platinum) and drivers 92.91 isn't this supposed to support h.264 acceleration?

In fact when I try and open the clip Nero Showtime seems to be used instead of Purevideo even though this is my preferred decoder?

Any clues ;)

have you tryed playing the clip with windows media player?

that is how i have played 1080p clips before, an nvidia decoder options box becomes available where you can select hardware decoding.
 
ive just given it ago again, reformated recently so ive got no decoders (e.g purevideo) or Power DVD software installed.
using the 91.47 drivers i only get about 33% cpu usage on a 1080p clip :confused:


could you try it with nero codec uninstalled, see if it makes any difference?

i will install purevideo in abit and see what performance difference i get, if any
 
it won't work mate.

i tried this for ages and i could not get purevideo to do anything other than accelerate mpeg2 video. its media player that is bust. microsoft will not incorporate hardware wmv acceleration in media player 10. they hoarding it for vista.
 
dvd's don't even require hardware acceleration. they need to fix the DXVA in media player 10 so that all hd content uses hardware acceleration where available.
 
There's a DXVA patch from MS (it's on Guru3D as well), but that did nothing for me with my AGP 6600GT. Recently got an email back from nVidia support (after waiting ~11 weeks) saying that HD decoding on all AGP 6 series cards is borked, not just on NV40 :rolleyes:

Obviously that's not exactly the same case for you, but it wouldn't surprise me if it was nVidia's fault.

well it still did not work on my 7600gt or my 7900gs. its just borked plain and simple.
 
Yep I have DECCHECK installed and it show Purevideo is the preferred but it seems that anything h.264 is always decoded by some other codec, it used to be Nero but since installing PowerDvD it uses that!

Weird thing is that Playback through PowerDVD is pretty good with low CPU (19/25%) usage but if I play back through WMP even though it is using the Cyberlink h.264/AVC Deconder (PDVD7) codec then CPU usage is much higer (75/85%).

It seems that the hardware acceleration is not being applied in WMP10 even though it codec is capable of it :confused:
