HD 2600XT and 1080p

[quizzelbuck]

When i run the HD 2600XT on my 1.8 ghz CPU, the computer behaves as if the card isnt installed. Infact, if i take the card out, and run the damn computer, onboard video runs the same files practically the same. Some thing isnt configured right, and the video card isnt taking the load off the CPU. what am i doing wrong? is there some thing i can do to get the work load transfered to the video card?

You have to use a player that will utilize your hardware decoding abilities. Such as AnyDVD

VLC wont?

 

[BassBomb]

No

Ok, maybe i should also ask this. Will this video card do any 1080p file or just VC-1 Mpeg 4? will it do high def divx? Thats what ive been using to test this out. What should i be using if this isnt the case? I should also add that i got AnyDVD HD and it isnt decoding the files with the video card. Is it because its not an actual HDdvd or blue ray disk?

With the right player the following formats are accelerated: MPEG-2, VC-1, H.264. Divx will not be accelerated, not that it really needs it.

Ah, that makes things a little clearer. I am running a 1.8 ghz chip, and a gig of ram. The chip is an imbedded ITX deal and really runs at some thing mor comparable like a 1.5 Intel or maybe a 1.6. Having said that, i would like to know what i can do to get my hi def divx stuff working better. You have all been so kind to share this knowledge with me. I have been struggling with this for some time now, and i must say these anandtech boards have been the most help.

Ahh, with that slow of a chip I take back what I said, I can certainly see you having problems. Other than turning post-processing off, there's not much you can do. In theory DivX could be accelerated since it's just MPEG-4 ASP in an AVI container but no one has bothered with it since it's not a "real" movie format like MPEG-2 (DVD) and VC-1/H.264 (BluRay) are.

The one that's a lot of trouble is 1080i. The HD2400 can't handle deinterlacing 1080i (ATi supposedly fixed this in the newer UVD on the HD3450). The HD2600 Pro and above (XT, 2900, etc.) should fully handle H.264 and VC-1 just fine (entropy, mo-comp, etc.)
