HTPC nVidia Pure Video Hardware Acceleration

I want to disable the nVidia Pure Video Hardware Acceleration setting, does it do anything in DVD picture quality or it just lows the cpu usage ?

 

It is my understanding that Nvidia Purevideo uses the graphics card for its hardware acceleration. It adds better video scaling and de-interlacing so you may find that the picture quality goes down and that the cpu load goes up or stays the same.

There is an option in the Purevideo settings to enable hardware acceleration so just untick this and see what happens.

To get to the settings play something that uses the decoder and an aditional nvidia icon should apear on the right of the taskbar.

Hope this helps,

I did that and I didn't see any difference, other than with hardware acceleation enabled, the card get more hotter.

 

I think it just takes some stress off the CPU by using the GPU instead, but I could be wrong.

 

same cpu usage same quality, the only change the vga card gets hotter when enabled

 

Well if you can't see any difference in the picture and you are concerned about your gpu temp then I would dissable the hardware acceleration.

Could I ask what sort of video you are playing. It way be under this case there is vary little for the card to do in terms of improverment.

it is mpeg2 video using it with my DVB-s player

 

purevideo only helps when you use the nvidia mpeg 2 decoder.

 

when playing MPEG2, my CPU usage goes down 10%, and it hits the card harder. No visible quality change noticed here... just offloads the CPU overhead.
