Well that's great now! I'd be willing to bet that more than a few people at nVidia are being slow-roasted over this. $400 for a fly new card and $125 for a water-block to keep it cool and I still get porked.
Man, the old lady is going to tease the crap out of me, if I ever tell her about it.

Me too, just not because of the PVP :thumbsdown:Originally posted by: THUGSROOK
yes, my HT is always disabled
no dropped frames, smooth as silk full screen.
Er yeah, but not thanks to the PVP but rather HT. See my post above.

Edit: replied to "unfresh" page before subsequent posts...
Can you dis/enable 5950 acceleration to test if it helps or is it indeed just CPU MHz? Why aren't you using HT is the other question? Windows 2000? Still, I maintain that it is the encoder that this is really about.

Well something in the P4 architecture makes it excel from perusing the benchies, perhaps it is just raw mhz in the end that is the best for the WMV9 and WMV9 HD content in both encoding and decoding? Anywho, it is also one of the real "burns my ass" points that my GT is borked while older gen cards perform better in this area :| I'm a gonna sell this thing and get that pro VIVO.

This board is a poor substitute for a chat room. I'm not replying to anything more until 3:00 AM or something when it's not so busy. :laugh:

The 5900 does not support hardware accelerated WMV like the 6800 is "supposed" to. The Hexus benchmarks bear that out as well. The T2 trailer is much less demanding than Step into liquid, and it took 82.14% CPU to decode using a 5900 (which is about where my AIW 9700pro is ~and maybe a little less than my broken 6800). THUGSROOK's 50-55% cpu usage while running Liquid (1080p) would be the lowest cpu usage by a fair margin of any I've ever seen (even with his CPU at 3.7 GHz) unless HT was enabled. I would like to some similar results, or perhaps maybe THUGSROOK could double check his settings (1080p version, HT disabled, using WMP9/10 and which renderer you are using. Give the stats off the statistics page in WMP)

That's false. I posted a link months ago in DP's first thread on step to the liquid, with 5950 and axp@2700 doing less than 50% the whole trailer and skipping no frames... I can't duplicate right now cause I ripped all the memory off my card.. Someone?

But what renderer? Overlay Mixer is hella faster than VMR7 or 9 when HT is disabled.
People should test with Media Player Classic so they know and can control exactly what filters are used.

Awesome, thanks. I really hadn't seen any rig without HT enabled decode that file with CPU utilization that low (and I missed Zebo's post in the other thread, as well as seemerun's) so I stand corrected, but don't actually understand how it works considering the 5900's video decoding architecture. I skipped the last gen NV cards, but my ti4200 (or any of my Radeon's) certainly won't even come close.
Do you have a link to 5950's WMV decoding architecture, all I can recall is the Hexus review where it works like I expect (somewhat high CPU use, why wouldn't there's have been much lower than 50% even, considering T2 Extreme is far less demanding than "step into Liquid" is it because they used a 5900? Link), but I'd like to check out what makes the 5950 actually work so well.
I've emailed Leadtek a few times now and they keep telling me that my problem most likely lies in the software I'm using. They claim that Windows Media Player doesn't support hardware decoding of any kind and that I should contact Microsoft.
Is that complete garbage, or what?

How? I just see VMR on or off and if on some sub options. I don't see all a list of filters in use during playback either.

Sorry, I meant you could choose the renderer, you're right about filters absolutely. I use Graphedit myself and build the filter graphs to test the videos. WMP was just used in these tests because most everyone has it installed and it shows the framedrops, and gives you the ability to change renderers as well. But you are right about the filters.

Not as a thread crap or as a "well they do it too", but I have not yet seen evidence that the ATI X800 series is doing any better yet. I cannot test it. The current machine I have to run in only has a 2.0GHZ processor with 256MB of memory. Framing is an issue on that machine. (I have another box, but it is SFF).
The X800 Pro card ran really well on a 3.0e, but it was before this thread that we had to return the PC. HT was on. I do think we were pacing at around 30-40% CPU utilization with SiL 1080.
Has anyone tested the X800 yet with this same experiment?
I know I had asked about this earlier, but none of us had seen them yet. Both nVidia and ATI could or would not answer what the net benefit was for WMV as a decode assistant. Maybe we get an idea why nVidia could not answer it Still not sure what ATIs excuse is yet.
