lol my bad. thanks. I've been saying VPP for some reason. on chip Video processor is how I think of it/what i mean. VPP is the nvdvd codec thing i've been using for dvd playback. which I find really nice by the way.

Good post dude!
BTW-
You dohave to read posts other than this one, Big Chief. My Asus X800XT PE is arriving tomorrow or the next day, (shipped Friday) do you think my posts about that will be "Yay nVidia!"? :roll:
LOL-dude, I have purchased almost every flagship card by every company for the last ten years. I put my money where my mouth is when I say I'm no one's "fan boy", how about you?
LOL- usually I try not to feed the trolls, but one of my buddies PMd me about your ludicrous manifesto, so I read the first paragraph and wrote this. If you were here, I'd buy you a beer for the laughs.
:beer:OOOPS! Better quote you so I don't end up on vacation like your alter ego, Hard Warrior. I wouldn't want the mods to think I'd call anyone the "world's loneliest man" without them having written a 10000 word term paper about the "Evils of Rollo, ATI Buying nVidiot".

You're off-topic again and otherwise hijacking the thread again, Rollo. Anyway, 7-days and counting.
i will not lose faith!!!!!
its a programmable video processor....they can program it to work, they can they can!
please!!! ah!!!!!!
its a programmable video processor....they can program it to work, they can they can!

Oh,you've bought an ATI, congratulations, Rollo. Great, I'm glad for you. And Damn, I thought I had you figured out based on your subjective and one sided viewpoints supporting Nvidia unconditionally...Damn, I had witnessed such things and assumed you were an unconditional Nvidia defender no matter the circumstance, but I guess your words and viewpoints mean nothing now, since you've said you bought an ATI card and all :roll:
Thats the famous words of every fanboy "I own both company's cards" Whatever. It doesn't change the fact that you worship Nvidia, and defend them no matter the circumstance. You know it. I know it, and everyone reading this thread knows it. By the way, you're not the only one to get PM's (if you have at all) I've gotten 4 PM's from people laughing and complimenting me for ripping you to shreads. and 2 more saying not to bother with Rollo, "he has no respect around here ect..and hasn't the ability to even carry on a reasonable debate with since he's so biased" Now, I don't even know anybody here, these are strangers approaching me and telling me this about you, not some of your forum buddies trying to make you feel better and cheer you up after you've been taken to the whippin post..lol. Gosh, you'd think people would have more respect for you and be more grateful after all you've done around here for everybody....I mean, golly, you did get those Far Cry ps3.0 benches early and all.
As for me calling you a fanboy, It needs to be said, because in the context of this thread and how you've responded, it's more than pertinent. In response to me calling you a fanboy you say "You do have to read posts other than this one.....I've just gone and bought an ATI...."
Fine, I did just that. I did a search. LOL, it took me all of two posts into your search to pick out this gem:
Next, someone says this would be much less of a failure than the 5800. Which no one in their right mind would argue, since The 5800 is almost universally regarded as one of the most notorious and colossol failures in 3dhardware history, second only to the 3dfx voodoo fiasco. The exception to this is Rollo of course, in his Nvidia fanboy world he sees everything through a false lens...and he is somehow able to put a positive spin on the 5800's cancellation and never reaching retail....claiming they were available everywhere...LOL:
lol, You see, ATI's x700 cancellation is a disaster, but the 5800 not so. ...Even better, in a post a day before about the NV48 being cancelled, Rollo amazingly was singing a different tune yet again...you see, if its Nvidia, then well.....
So I go back and look 2 posts into your search results for posts, and that comes up. Come on dude..you're an Nvidia FANBOY> I'm sorry....It colors any opinion you have. You are completely blinded. Same post cont:
someone with some common sense(sickbeast) had this to say:
" - Rollo I'm still shocked you're downplaying PS2.0 yet you continually stress the importance of SM3.0. Face it, the 5800/5900 cards would be much better pieces of hardware if they could run HL2 in DX9 mode in similar fashion to the 9700/9800. The 5800/5900/9700/9800 were not "low end" cards when Far Cry was released, by the way. "
Yeah, I'm shocked too, imagine that, Rollo downplayed ps2.0....but now ps3.0 is a must have. Real consistent and objective there Rollo. Its got nothing to do with your Nvidia bias, I'm sure :laugh:
another gem, same post:
Now I don't necessarily disagree with a lot of the above, but there is unquestionable ATI bias in there and pro Nvidia slant, and nobody except yourself Rollo, would mistake you for a fanboy.
...for some reason, Rollo doesn't seem to be a fan of the graphics in Hl2...i wonder why?
THats a good one, i like that. Something tells me Rollo likes Carmak better than Gabe.
Here is another, Now, these are all comments from the last 20 of Rollo's posts, mind you:
here is someone the other day complaining that his new Leadtek 6800GT is loud and asking for advice, of course, Rollo doesn't like that one bit
here we go, here is Rollo on the Video Processor issue, he manages as always to get in some shots on ATI, all the while gushing over Nvidia's despite its flaw.

Oh, but no, YOu're not an Nvidia fanboy at all. There is no bias here at work in your opinions. You said I should read all your posts. Well, I didn't have to, these came up within the first 20 search results for Rollo....there are people in these threads calling you Captain Nvidia, and literally every post, is either a pro Nvidia gushing love letter. Either that, or you manage to bash ATI in one way or the other. I said a longtime ago you were the quintessence of a fanboy. It doesn't take a genius to know that I wasn't that far off the mark there.
You say I'm lonely, or have nothing better to do than to give you a hard time..fine, for arguments sake, I concede the point. But defending Nvidia's honor appears to be your raison d'etre around here, because you do little else. Just come out and admit it. You are an Nvidia fanboy through and through.

I don't want to get into any flame war and I am not defending the PVP since it is obvious that it isn't doing any acceleration, but I think we need to be honest about the alternatives. Since there have been MANY comments about the 6800 being the only one to tank so hard on WMVHD, I wanted to post an opposing view. I have tested Step Into Liquid on my A64 3200+ with my GFFX 5900 and 6800 and I get almost identical results (floating around 80%). Given that those are both nVidia cards I decided to test it on another machine, a P4 3.2E with a ATI 9700 to be exact. With Hyperthreading ON the clip plays fine in the 40-60% region, but as soon as I disable HT guess what? Yup that is right the ATI also jumps to high 80's and dropped about 14 frames. Does this prove anything as far as the PVP feature of the 6800, nope just shows that none of the DX9 test cards seem to be doing anything but leaving the heavy lifting up to the processor. I understand everyone is upset about the card not doing any acceleration, but the single biggest issue seems to be focused on WMVHD and that doesn't appear to play any better on the two year old DX9 card, like some have suggested.

Another good post and jolly laughs, Epking!
I don't think I'm convinced I'm a fanboy yet though- could you please look up some more posts and write another Off Topic essay?
BTW-
X The Answer
put your 6800 in the machine the 9700 is in now, and you will see exactly what I'm talking about. It will perform profoundly worse. You should run both cards test with HT disabled, and then make sure both tests are run in VMR9 mode. You will see a clear and unquestionable difference.
So you HAVEN'T been reading this thread after all. If you did read any of my post, you'd know the answer to your first question. Also what's with the I don't see it noted in your sig. I see your sig has no system so I can assume you don't have either the 6800 or the x800? -__-
In any case, your response is the same as the fanboy response that I've read approximately a million times. Hey, I've even written one of those responses myself in the early stages of the discovery. But that was before I realized there would be an impact on my ability to even play those. How am I damaged by this? I can't play wmv HDTV without heavy stuttering and frame drops. That's enough for me. my 5900 did better than this for reasons stated above by someone else.
you're not laughing. you're plenty mad. nice try though,
not much else you can say. you could always tell me you're gonna put me on the ignore again.

I hesitate to tip-toe into this particular flame-fest, but I just wanted to point out that the NV-1 itself, NVidia's first product, was actually the "most notorious and colossol failures in 3d hardware history". It should tell you something when the mfg's FAQ states that the card is essentially useless for 3D, totally DirectX/Direct3D-incompatible, and to treat it as a 2D-only dumb frame-buffer. It was the premiere product, that almost sank the company. The next runner-up for that position would probably be the ATI Rage MAXX. AFAIK, NT/W2K drivers were never produced that could utilize the second GPU on that card.
As for Rollo, well, I lambasted him enough earlier in the thread for being an NV fanboy.
I can't fault anyone for allowing something to make them happy, though. If NV video cards do that for Rollo, then so be it. But I won't let that detract or distract from the focus on getting the company to make things right for their customers over this current issue. Hopefully this thread won't degrade too much further into personal issues.For the last time it WILL NOT perform worse, since it is already completely dependant on the CPU. I don't understand why you have difficulty believing this, but I have tested it multiple times with overlays, VMR, no hardware acceleration and I get the SAME results across multiple machine and multiple cards. The CPU is doing ALL the work with the 1080 WMVHD version of Step Into Liquid and none of the three cards I am listing help the processor out much. This is ONLY pertaining to WMVHD since I didn't test the rest of media samples, but I have no problem believing the 6800 has higher utils on other types. But if WMVHD is the poster child for the future, currently neither ATI or nVidia seem to have a goods. I understand ATI is working on drivers that may change this, but current not the case on my test machine. As for testing my 6800 in another computer, I am not going to bother. If you don't believe me, fine. I simply wanted to post this information for anyone who finds it useful.
This doesn't mean that that PVP is working in the least. If you have proof that I am wrong I would love to see it, why not provide a screenshot of a 9800 on a A64 at 40% util since I haven't been able to find one. Everyone that I have found inevitably has HT turned on and thus isn't a valid test. I don't find my claims that outlandish since I have seen several post of people complaining their X800XT-PE is also using high util and dropping frames.

That makes perfect sense to me. My understanding of the "VMR9" display mode, was not that the GPU's shader hardware was actually doing any of the decoding work, at least not automatically, but rather, that it used DX9 surfaces to render the decoded video to (using the main CPU to do the decoding), which then allowed use of the GPU's shader hardware to further post-process the video before being displayed to the user. So various effects could be added to the video stream, like sharper/blur/de-interlace/etc. Now, I guess, that with sufficiently-powerful shader hardware on the GPU, it might be possible for the CPU to feed the incoming (compressed/encoded) video data to the video frame-buffer, and then let some custom video-decoder shader programs execute to process that data into a decoded format, that is then later post-processed and displayed. If NV is going to save face at all on the 6800 AGP PVP issue, that's probably what they are going to have to do. (Actually, if it takes an additional step in the process like that, or if there needs to be some custom way to load the compressed video data into video memory, NV very well might need MS to make some changes to WMP10 to accomodate, but that doesn't make that much sense either, since NV has already been working with MS on the same issues for XP MCE PCs.)
Is there any evidence that the 6600GT's PVP is actually working? I know that was the rumor, but I haven't seen anyone post thier results. Another rumor is that NV does supposedly need WMP10 support, but I take that with a grain of salt since most inside sources are far from reliable. Except about the coming 20th of Dec, lets hope. LOL

malchite we are maybe misunderstanding each other. I'm not saying the other cards have .wmv hardware acceleration. what i am saying is this. other users in this thread and elsewhere are reporting the exact same thing. In my case, step into liquid plays fine in vmr9 mode on my xp3200 1gig nf2 with a 9500pro, 9800np, and a 9800pro. With the 6800 in there, it is a slideshow. 2 other users with 5900's in this thread, that i specifically remember, have reported the exact same thing. Now, how is this possible?, what could account for this? I'm by know means a hardware expert, but I know what I'm experiencing, and I know how to test it. Its practically all i've been doing in my free time is fooling around with these playback modes and dvd playback. I'm not claiming any of the radeons or the 5900's have .wmv acceleration, clearly not. But clearly, at least to my reasoning...something with the broken video processor in the 6800 appears to either over-burden the cpu because the other cards used pixel shader assist and the 6800 had bypassed that in the hardware thinking it would have a working onboard video processor or, I don't know, something else, maybe the drivers, or something on the 6800 is causing profoundly, and i mean very noticably worse vmr9 playback in .wmvhd. In fact, i'm seeing terrible performance in vmr9 across the board.
Also, it is likely the situation is much more pronounced on lesser cpu's, ie: one is much more able to notice terrible performance if ones cpu can't handle these clips as easy. In the case of the xp3200, before it was just over the threshold where it could play them clean with no stutter..actually in liquid, there was one frame that stuttered in the same spot...with the radeons...and somehow, now with the 6800, it is well below being able to playback and the whole thing is literally stuttering its way along. I've done two clean installs of Xp, tried every forceware available more or less, and a couple of nforce2 drivers. No change whatsoever. Before these clips played fine....same CPU. Now they play like utter shit. Again, I'm not a lone voice here experiencing this.

yeah, there are benches up, cpu usage is waaaay down. I forget where they are, but i think they are widely available.
this is how virtual larry is talking about dx9 shaders and these .wmv's... Malchite, doesn't it seem plausible that what I and others are experiencing is the older cards handling it in the shaders without issue and most likely aleviating some strain off the cpu....and the 6800 could, well, even likely to have problems since it was designed for an on-chip decoder in the first place, and said decoder is disfunctional. Doesn't this make sense? Another possibility would be that perhaps since the 6800 has, was supposed to have the on chip decoder, then the shader hardware on the 6800 was tasked with more sophisticated, more cpu intensive post processing. This may account for the superior image quality I'm experiencing as well.(wish i could use it..lol) Since the on chip decoder isn't doing its job, then the more sophisticated post processiing coupled with the added burden from no on chip hardware....then this makes the clips unplayable on users machines, where before with other cards, they were much more playable. I would think both of these a possibility. Irregardless, this many users can't be wrong, before the upgrade they could play the clips, after the 6800 series...no go. Now, this obviously, would only occur with users within a certain cpu range, but reading this and other forums, I've found that the incidents of before/after nonplayability, go as high as users with A64's. One claimed to have an FX that played it before the upgrade but not after.
you know, i'm just thinking if nvidia, or anyone in tech support or pr happens across these threads as we try to figure out, maybe occasionally touch around the truth, but mostly stab in the dark about ultimately WTF is up with this stuff, you have to know they just snicker, if not out and out laugh their d*cks off.
I guess why I have a hard time believing that it the I tested a 9700 on a 3.0E that should be able to handle it and it still dropped frames WITH full acceleration but without HT. It did NOT run in 50%, but rather in the high 80's low 90's (hmm seems familiar) and if what you are saying is true that would have been WITH the GPU offloading some of the strain. Thus why would a even slower GPU and slower CPU perform any better than the 9700 with a 3.0E? That doesn't seem to make any sense, if there are people reading this that are running 1080 WMVHD (on a 9x00 without HyperThreading) in the 40-50% region without HT just take a screen capture and you'll have proven me wrong. Like I said I was aware of the issue before I installed my 6800 so I put my old 5900 through the tests and found it to be no better with WMVHD. Then when you were in doubt I decided to try a 9700 and I once again got high CPU utilizations without HT.

Well my system is well below an FX an I never drop a frame so I don't know. Bare in mind, if you believe anything on the Xbit page the forcewares were really broken before and now maybe they just don't hinder the performance.

Right, after months of views, opinions,driver fix this...driver fix that, boring flaming, whining,moaning etc
Lets just all assume nVidia went bust yesterday and cannot do a damn thing to fix the issue, does anyone here have the knack for creating/modifying drivers to the extent where we could perhaps fix this ourselves?
After all, if the gospel has some half truths and a driver fix is the magic ticket, it can be done ....whos to say it has to be done through official avenues, what are nVidia going to do? sue someone for tampering with their tech.... wouldn't suprise me, but if so , have my permission to pin the blame on myself, I will gladly confess.
Anybody?

what happens is the cpu is always high, on the rads on my xp3200 and the 6800. The 9800pro for example is up in the high 90's, however, it plays the video. The 6800 is in the high 90's as well, but it is a slideshow. This is mine and others firsthand experience. I'm not sure about the HT with and without or the Intel/AmD how apples to apples it is. All's i know is this is what happens, the 9800 can play it, the 6800 cannot, and not even close. As I said, others are reporting this all over these threads. We are in the realm of theory and what should happen with cpu usage, particularly your argument, however, no offense...but mine and other's experience is saying otherwise. I think this divide between us is in part due to differences in yours and mine's hardware, mine and the others reporting this appear closer to the threshold of what can and cannot play WinHD. Now, I see what you are saying about cpu usage, there should be no difference, However, try to look at it from my perspective. For a second try not to think in terms of what should happen as far as cpu numbers. Think merely in terms of whether it plays satisfactorily or not. In the same machine, these vids were playing before the 6800 upgrade. Now they are not. Whether that makes sense or not... it does appear that is exactly what is happening for a number of users across these threads. If I remember right there was some discussion on this waay back towards the beginning of this thread..along with some comments on HT giving false positives.

That's what I was actually trying to point out, epking, I think that you're probably slightly wrong about that, or at least the assumption that the potential ability to use shaders to process the video means that they somehow automatically are doing that. VMR9 means that the drivers/codecs could use shaders to process the video (either decode or post-process), but based on the CPU numbers, it appears that they aren't. (Or maybe they are? People have suggested that ATI's drivers have some sort of HW video-playback/WMV-acceleration for a while now, but I haven't seen any concrete, testable evidence to verify that.) OTOH, perhaps the current batch of drivers for the 6800 have problems handling the VMR9 render mode period? Have you verified whether or not FastWrites are enabled (with WCPUID or PowerStrip)? Does your 6800 still stutter in Overlay render mode as well? I guess the only reason that I'm suggesting that is: 1) CPU usage numbers between different older cards on the same system seem similar (right?), and 2) I don't think that there are many older pre-6800 with a powerful enough GPU to meaningfully offload decoding tasks to the shader hardware anyways, for WMV-HD content, save for possibly the R350 and newer GPUs. I have a feeling that something else is going on, not shaders, but perhaps the motion-compensation engine or something. That actually would seem to fit your theory slightly better, if NV took that out, intended to utilize the PVP for that feature, whereas prior cards had that as an integrated dedicated hardware function. Supposedly the FX5900 has an excellent hardware MC engine implemented, as I'm sure ATI cards of a similar vintage do too.
Clearly, there is something going on with the 6800, in that it seems to be not only no better, but in fact worse, than prior cards, but I don't think that you can definately point to some sort of shader-based video-decode acceleration on prior cards. If there was, then by varying the GPU clockspeeds, keeping the CPU clockspeed constant, you should be able to directly measure the relative CPU offload by the GPU shader hardware. That would be one potential way to test.
Edit: Some info about ATI WMV acceleration on the bottom of the 2nd page of this thread . It seems to indicate, although the drivers support it, it can't be enabled without some fix from MS, and therefore hasn't worked yet without it, so they're removing the option for now? I wonder if that has any bearing on this 6800 AGP issue?
ok, thanks so much virt larry for the explanatory post. yeah, about the shaders, someone mentioned it earlier, or in another thread..it makes sense to me. I'm just trying to figure out why I can't play these clips anymore. If you don't think this is so, at least there appears to be several other explanations and possibilities. LOL. As for how i do vmr9 and overlay ect...yeah, i'm sure its turned on right, I'm setting it up first through WMP, and then later on for more advanced options, through zoomplayer, and have tried every possible combination of output modes in VMR9 yuv,rgb32, and all those modes. Nothing made a difference. Also, yeah, I have tried with and without fastwrites just in case, I leave it on by default. I've even tried turning on/off sideband addressing, anything i can think of, i've tried. I've got two full WinHD movies I haven't watched yet, Step into Liquid full movie, and Standing in the Shadows of Motown.
About the clockspeeds and shaders you mentioned, I'm not sure if this is why or not, but over at AVS, the HTPC gurus always recommend 9700pro and above as ideal for HDTV playback performance, anything else can't handle without stuttering..which I guess I'm getting confused, but if its soley a cpu thing, then why would these gpu's matter for HDTV playback performance? To throw another one out there, because I honestly don't understand, the big thing now with these 6800's, if you have the system, is to use AA and aniso in DVD and video playback. I didn't believe it when i first heard it, but it does indeed make a difference. Do you have any idea why that works, or why/how it might work? and if that has anything to do with what we're talking about? Sorry for the ??'s, if you don;t have time no worries. I appreciate your knowledge though.
about that edit, and the hardware accel in .wmv Could there be any sort of difference or any sort of "assistance" that occurs in the rads, possibly the FX cards? Doesn't VMR9 mode work through the hardware (shader pipelines) in some way by its very nature? Its just not full hardware acceleration? To be clear, I'm asking, not saying..lol. I really don't know, and would like to. I was always under the impression though, that VMR9 used some of the videocard hardware, i think pertaining to color output space in particular?
I just looked it up, here is a VMR9 definition from google one of the first couple entries of course:
