More NVidia PureVideo Decoder testing: conclusion - NVidia DxHA stinks

[wtg]

first off i see you're not using the anamorphic aspect ratios...anything else always messed up my aspect ratios....

Well, I don't know how you see that or what anamorphic aspect ratios are... teach me something

also, have you fiddled with anything on the color tab? if you do you'll see significant performance issues...!

No, they are all at their defaults.

also, i notice you're getting only mode A accelleration..[idct only]
every Radeon ever made does mode C at least[idct and motion estimation and something else]..i thought the 6200 had hardware accell...my fx5200 does same as yours..maybe a driver version issue..i heard things..try older ones..

Well, I haven't looked at my old Radeon to notice this, but my old 9200 sits in my daughter's machine and I just installed gb-pvr in client mode yesterday. With the ATI-specific Cyberlink drivers she's averaging 16% CPU-utilization! Old card, lower-end machine - shows me just how badly the NVidia card or drivers are performing. I'm gonna go have to see if I can figure out what mode my Radeon is using.

I plan on taking the other advice above and trying older NVidia drivers today. I don't hold much hope though.

also, is that a agp or PCIE card? big differences between the 2 for memory transfers...

It's AGP. But shoot... this isn't the latest gaming rig and doesn't need to be. My old Radeon 9200 is proving more capable than my NVidia 6200. I may have to put in back into this machine to prove to myself it's not something else in the box that's doing this, and if so, go out and get another Radeon card. I read of other problems with a wide range of NVidia cards so I don't think it's really just a 6200 problem.

Ah, I see what you mean about the anamorphic settings. Tried it... no improvement.

Now, I did download and try the 84.21 drivers. That improved the Overlay mode performance considerably, but offered no improvement in either VMR7 or VMR9 modes.

I've included the Overlay graph below. It essentially matches the performance I was getting out of GraphEdt and WMP. I'm still not happy given the aspect ratio controls you lose going to Overlay, but it's a considerable improvement nonetheless.

ahhhh, agp.. that card is special when it comes to memory tho...
creates performace issues....tho i would think the agp one would be better..

in the pcie one, they don't use actual memory, they use system memory...
a 256 meg pcie card only has 32 or 64 megs onboard as buffer, actual mem is system's...[read slower]
i read several comparisons that showed big differences in the mem transfers between the 2 cards...but from memory, the agp one was faster on most things..but it's been a while...

i really think it's the driver...lots of chatter about the newer ones breaking accell in all but newest cards...
and the mode thing is what to keep an eye on..anything over 'A' mode is great..

oh and anamporphic aspect ratios are on the nvidia dec. config page,bottom of list.. [really just 'raw' aspect ratio, no changes are made to it]
