DXVA Checker - Anyone Using This?

[Savage1701]

Anyone tried this? I have an older Pentium D 955 EE system with an 8800 series video card.

This utility claims to be able to, among many things, make sure any DirectShow filter that is compatible with your brand of GPU (ATI or Nvidia) will access its DXVA capabilities, assuming it has those to offer.

I prefer DirectShow filters, but they can tax the CPU.

I put this utility on and set my Nvidia PureView Decoder pack decoders to use DXVA (They were not according to the utility).

All of a sudden my CPU use drops into the single digits. Picture gets way better ( especially that bullet scene from CSI). I can see something's been offloaded to the GPU because it's temps climb about 5 degress Centrigrade.

I tried it with H.264 sourced at 1080i and 480i via a HD-PVR, OTA ATSC, MPEG 2 from a PVR-USB2,

Something happened. Something wonderful...

DXVA checker doesn't itself enable anything, it just shows you what your decoders, and video drivers, are capable of. The setting you changed was a setting in the decoder, not DXVA Checker.. Still, DXVA checker is quite good at showing you what decoders you should use, and what not.

My point exactly - I would never have been able to change that decoder settning without the uitility. Sorry about the sloppy phrasing. Never seen a utility aimed at that.

my point was that you can access that setting in graphedit as well, by pulling up the decoder's properties.
