What's your CPU usage % while playing 1080p video?

I have a 128MB Nvidia Quadro 570M on my T61p, which has the PureVideo HD feature (hardware H.264 decoding), and my CPU usage is around 50-90% while playing this H.264 video. It is a bit higher than expected. It says that the hardware H264 decoding (PureVideo HD) on Geforce 8400/8500/8600 is expected to reduce the CPU usage to 20-40%.
I am wondering how many people have noticed such a low cpu usage when playing 1080p H.264 video?

 

I just played a 1080 vid to see. Almost 50%, I thought was using 1 core 100% but no I checked it used both. I have 1150 so don't think I don't have PureVideo. Gotta love IGP?

 

I'm on a Sempron 3100+, 1.5GB of RAM on Vista + 8600GT XXX PV HD + HDCP on my desktop and I can't even watch the FF13 HD Trailer in 720p, nor can I do on my dad's laptop, wich has a Turion TK X2 53 and 1150

What's your CPU?

 

It depends on your mediaplayer/codec/filter. Not all players support full purevideo for all codecs.

 

I tried both WinDVD8 and Windows Media Player Classic(comes with K-lite Mega package), and got similar result (CPU usage 50-90%). Would you recommend a player that supports PureVideo HD? The media file is encodec with the standard H.264 from Apple, which I assume should be supported.

 

MPC doesn't support it (well, it does, but it's a horrible implementation), and you need to turn it on in WinDVD8, since it's off by default. Quicktime supports GPU accelerated playback, but the QT decoder is so bad, that you can't watch it without the GPU. Try WinDVD or PowerDVD. Just remember to patch to the latest version and turn it on.

I would also ditch K-lite mega package and install CCCP instead ( www.cccp-project.net). Much better codecs (filters actually, but they perform the same job).

 

Patched WinDVD8 to the latest version, enabled the hardware decoding acceleration options, tried two different video card driver version (modified 163.67 from laptopvideo2go.com and the latest windows driver from windows update), I also tried zoom-player in CCCP, but I am still seeing the same 50-90% CPU usage.
Maybe this particular .mov video is encoded in a unusual way that can not be handled by PureVideo HD? I know it's H.264 because it is one of the Apple H.264 sample video.
Any suggestion?

Btw, when I say "50-90%", I meant both core is running at 50-90% load.

 

Is your cpu throttled to full? with battery plugged in?

 

The CPU is running at 2Ghz, with power plugged in and power theme set as "maximum performance".

 

try the 163.44 drivers?

 

Using nVidia 140M I reach about 50-60% CPU usage when running that video in your original post.

 

Ok, that's a crappily encoded vide. Quicktime stuttered, MPC wouldn't allow me to use external filters, so that stuttered too. VLC worked better since the internal filters are better (kinda like ffdshow). Windows media player allowed me to use CoreAVC, so that was smooth. The problem you had with Windvd could be that it doesn't recognize the container (for HW acceleration), hence just using the CPU to decode.

You have uninstalled the K-Lite mega pack, right? And zoom player ain't the best.

 

Yo, any dudes here with a X61s with the L7500 processor?

I need to know if that thing plays 1080p movies nice and sweet, because I'm planning to buy this little bugger.

 

OK, so it's the video itself that causes the problem. I just used mencoder to re-encode it with X264, and then it can be played smoothly. That's weird.
Yes, I have removed K-Lite.

 

I hope you're planning on running this through a dock to a large monitor? Otherwise its a complete waste at 1024x768, which is the only resolution the X61 and X61s come in (at least in Canada).

 

Sure thing, there's a Beovision 7 waiting for it.



Unluckily it's not Full-HD, but I want this X61s to last a few years and to be ready for a new telly.
