Thats exactly why the 7000 series won't be all that great. Their architecture is old and over-used, they need something fresh - just shrinking it won't help all that much. (Unless i missed the news on a new architecture)

On the other hand, they shouldn't take too much after Bulldozer - less performance then previous architecture is not good for selling stuff.

That was a side blow to Bulldozer, as its efficiency sucks big time, while people were expecting an Intel killer. Regardless of the production process.

I'm surprised. 6850 performs well and is priced well for example. Imagine it with 1/2 the power consumption. "won't be all that great" doesn't come close to my expectations.

BTW, HD7000 series will be 4way VLIW architecture across the board (6800 and below is 5 way VLIW - less efficient). Apart from the high end 79xx card wich will be a new architecture called GCN

I'm not saying the cards are bad, but AMD has been milking the same base architecture for years, at some point you just hit a wall. They can certainly hide that wall with going to new processes and some jiggery pokery, but something fresh would do them good, too.

PS:
Half power consumption is rather unlikely.

power consumption for an existing architecture can't be halved without changing the architecture unless the architecture was very inefficient to begin with which is certainly not the case.

Wrong. After a die shrink you can operate on a lower voltage too. Expect noticeable efficiency gains as a bare minimum.

From one generation to the next, it has been normal to get twice the GPU for the money. 40nm to 28nm is a bigger step than normal, so it's reasonable to expect more than twice the GPU.

If my calculations are correct, the 6870 would be only 44% of it's current die size at 28nm compared to 40nm.

Kepler seems a lot more exciting than the 7000 series, and definitely the cards to be waiting on if you plan on gaming. (AMD drivers have been disastrous for a number of big releases recently, Rage in particular)

This resulted in both madVR and LAV CUVID having about the same GPU load ~80% while EVR was around 50%.
Then I decided to lower my upscaling settings in madVR to Bilinear for both chroma and luma (even though the luma wasn't important since both video and display were 1920x1080) and this lowered madVR's usage to ~70-75% which is still ~25% above EVR.
With which renderer did you test LAV CUVID? madVR generally does consume more GPU than EVR, because madVR does many things via pixel shaders, which is more "expensive" than using hard wired video processing circuits. Interesting would be:

(1) "LAV CUVID+EVR" vs. "DXVADecoder+EVR"
(2) "LAV CUVID+madVR" vs. "SoftwareDecoder+madVR"

I would expect you to get somewhat similar GPU numbers for "LAV CUVID+EVR" and "DXVADecoder+EVR". Not sure about (2). Depends on whether video decoding is counted as GPU usage. If it's not, I would expect you to get somewhat similar GPU numbers for "LAV CUVID+madVR" and "SoftwareDecoder+madVR", too. But of course the GPU numbers should be higher for (2) than for (1).

I guess those that don't look like Bob are probably soft-telecined, so that DXVA does not really do anything but let the frames pass untouched (weave). Just a guess, though.

Sure, in the long run there are things that can be done. One step at a time.

Radeon 5750 using latest drivers (11.10).
That's really bad. Can I have a log, please? Also, can you step through the video frame by frame with both EVR and madVR? Maybe when looking through both frame by frame you can see why it's smooth with EVR and not smooth with madVR? Maybe madVR repeats each frame twice to achieve double rate, while EVR really produces fluid unique frames?

It might be worth trying drivers 10.11. But I'd really be interested to hear your results when doing frame-by-frame stepping with your current drivers.

Maybe creating and uploading a madVR log would help. When creating the log, please try to reproduce the problem with the first pause, then when the subtitle disappears, close the media player at once. That will help making the log nicely short. Thx.

No, I meant 10.11, because other madVR users already reported that these old drivers help get smooth deinterlacing results, while newer drivers seem to make problems for some users (but not all).

But please check out my reply to mr.duck (see above). I'd like to get a log file from you, too. And I'd like you to try frame stepping to get to the bottom of the non-smoothness, too. Thx.

Does it only occur with Haali but not with LAV Splitter? Does it only occur with LAV Video Decoder but not with other decoders? Does it only occur with madVR v0.78 but not with older versions? Does it only occur with PotPlayer 1.5.29996 but not with other versions? I'm asking because you're asking a lot here. Finding, downloading, installing and testing these exact versions of all the various filters/player would take me quite some time, and I don't really want to mess up my own filter configuration.

I've tried once again, this time in fullscreen exclusive mode (tested only in windowed mode before), still no problem. I'm testing in XP, though, where there's no DX11 presentation mode. What happens if you use DX9 instead of DX11 in the madVR settings? Does that change anything? The DX11 path is known to be not as stable (yet) as the DX9 path.

Some unexpected behavior: When i hit ctrl+shift+alt+d I see no combing yet the annotation says de-interlacing is off.
If the annotation says deinterlacing is off, then it is off. So it doesn't seem to work as expected. Either madVR thinks activating deinterlacing isn't necessary (this can happen if the movie was fully soft-telecined and all frames are marked as progressive, even though the container is 60i), or activating deinterlacing failed. Seeing that other Intel users report that deinterlacing failed to work at all for them, my current guess is that the current madVR version isn't able to get deinterlacing to work at all on Intel GPUs. I'll check this out on my Sandy Bridge laptop. To be honest, my plan was to look at Intel in one of the next versions. For now I've concentrated on ATI + NVidia, because the majority of madVR users are using ATI + NVidia. But don't worry, I'll get to Intel soon enough.

The bigger the output resolution, the more GPU RAM madVR needs. It might be possible that 256MB is not enough for 1080p playback, I'm not sure. I plan to make the queue sizes adjustable soon, so you can save GPU RAM. That might make it work for you.

So do you get a picture or not? madVR has decoders on its own, but if they get used, you should see a picture. I guess you see no picture? I'd suggest that you try a different media player, just as a cross test. Also try getting the latest PotPlayer version.

Good to hear that the internal decoders seem to work well for you. As an alternative you could also try LAV Video Decoders, if you prefer using external decoders. What you describe sounds like a problem with the external decoders you'd been using before.

DXVA *deinterlacing* does work with madVR, just not DXVA *decoding*. Whether DXVA decoding will work in the future or not I don't want to comment on at the moment.

What does "don't seem to pause" mean exactly? Do they continue to play, line after line?

Showing different context menus for left and right click is not that unusual for tray icons. The right click context menu has more menu items. The madVR left/right context menus have a clear logic to them:

The left click menu is just a menu for the currently running media player, where you can do all kinds of things to influence the media playback. The right click menu contains all things you might ever want to do, including closing the tray icon process, changing tray icon settings etc.

The reason why the right click menu has so many sub menus is that it contains more functionality. Having all menu items of the right click menu in one level would be a usability catastrophe. The left click menu is so nicely simple because it limits itself to only control the current media player, nothing else.

I'm looking to build a 2nd HTPC for another display and thinking of re-using the 5450 there and upgrading the main HTPC in the theater room. Seems like both ATI and nVidia have pluses and minuses (as always). Are any of the new integrated Intel graphics worthy of consideration? Running Win7, and mostly HD material, not even sure MadVR is really needed, but I do like to go for the best solution even if it's not something I can really notice. :-) Thanks for any advice.
If you can wait, I'd suggest to wait for the new 28nm GPUs coming out early 2012. They should significantly improve the power per watt ratio.

As to ATI vs. Nvidia, that's really a tough decision. NVidia seems to have big problems with presentation glitches in exclusive mode. ATI doesn't seem to have that problem, but then ATI has problems on its own. So it's really hard to decide...

Maybe the bug happens just extremly random.
Still can't reproduce it here.

This doesn't happen on my PC. Also MPC-HC, XPSP3, but ATI 6850. It *could* be an NVidia driver issue. But then why does it not happen with the internal madVR decoder? That's really weird. Maybe nevcairiel can have a look at that? He's on Nvidia, but I don't think he uses XP.

Ok, seriously. madVR has several queues where it stores frames that were already decoded, uploaded to GPU RAM, fully rendered and dithered to output resolution etc and passed on to Direct3D for presentation. Ideally, all queues should be full.

Still using 11.10 drivers, haven't tried rolling back or switching to NV yet.
Haha. Yes, that's true. madVR analyzes the GPU behaviour once during madVR startup (so you don't have to restart the media player, just reloading the video should do the trick). If you change the GPU driver settings while madVR is already loaded, madVR will not adjust to that, until the madVR instance is destroyed and recreated.

Going back to madVR 0.77 and everything is fine again. Fullscreen exclusive mode works fine in both versions.

All files are correctly identified as progressive. Also disabling deinterlacing in the settings has no affect.
The only thing that they have in common is a frame rate of 59 fps. Maybe the new version has problems with that high frame rates?
The only thing that comes to my mind right now is that maybe your GPU is downclocking with v0.78 but not with v0.77? I don't know why it should. But then I don't understand what else could be going on. Your render queue is the problem, so it seems that your GPU isn't rendering fast enough. Which is weird, since your GPU should be plenty fast enough.

If you're sure that the GPU clock is ok then please create a short log with v0.77 (no frame drops) and one with v0.78 (frame drops). Maybe 20 seconds of playback each. Thanks.

"the same thing/problem" is rather relative. It could mean something totally different to you than it might mean to me. Could you please describe exactly which problem you have? Having smooth playback in exclusive mode while you have problems in windowed mode is not usual in itself. There's a reason why I implemented exclusive mode, after all. The key question for me is: Did things get noticeable worse for you with v0.78? Because that's what cremor is reporting.

I agree that the new 28nm GPUs (both ATI + NVidia) are probably worth waiting for at this point in time. Ok, we don't know exactly when which cards will be released. But I also expect a big jump in performance per watt. Which is one of the most important things for an HTPC.

Weird. Can you please try 0.76 and 0.77, just to find out which version exactly broke it for you? Also please try different splitters and decoders, just to give me more information. Thanks.

Are we talking movie content or native video content (e.g. music concerts or sports)? Double rate is the right deinterlacing method for native video content. For movies things are quite different.

Not true. Older madVR versions required you to deinterlace before sending the frames to madVR. With older madVR versions the GPU never deinterlaced at all. With v0.78 madVR performs deinterlacing via DXVA and scales afterwards, of course.

When the PC first starts up the the display rate shown in MadVR is 50hz +/- 0.25% and playback is rock solid however after a while this then starts to vary like mad as described above.

Reclock during this time always says the refresh rate is 50hz as does the TV and the Nvidia driver/Windows. A reboot will always cure it, but i am trying to get to the bottom of this.

@madshi - where/how does MadVR get its refresh rate timing from please ?
Ouch, this is bad. madVR has a very complicated logic in it which reads the current VSync scanline from the GPU once per millisecond. Then it looks at all the collected scanline data and tries to do some very clever math to calculate the exact refresh rate. It seems that in your case the scanline data sometimes allows different interpretations (50Hz and 75Hz). I've never heard of such a problem before. This will be hard to fix. Does this occur in windowed and/or fullscreen exclusive mode?

I meant "bobbing" as in "some kind of double rate deinterlacing", not some specific bob algorithm.

"Bob" is called that way because the image bobs up and down if its used. Its not a category of algorithms that all do the right thing and use both fields to create separate images.

Oh noez. How shall I call it from now on, then? I always used it as a synonym for deinterlacers that preserve the full temporal resolution.

madshi, you were mentioning improving 24 fps clips on 60hz screens.
May I suggest an option to make 50% frame blends?
(frame1)-(frame1)-(50%frame1+50%frame2)-(frame2)-(frame2)-
(frame3)-(frame3)-(50%frame3+50%frame4)

The funny thing is, in the CE (consumer electronics) world video deinterlacing pretty much *always* preserves the full temporal resolution. Because of that there's not really a word for it (that I know). I consider not preserving the full temporal resolution a bug, and it usually only happens in the HTPC world. In the HTPC world people often use "double rate deinterlacing" to name the correct solution. So maybe you want to use that instead of "bobbing". But if you talk to CE engineers, they will probably not know what you mean by "double rate deinterlacing".

(Just to avoid misunderstandings: All of the above only applies to native video content. Native movie content is a whole different thing.)

May I suggest an option to make 50% frame blends?
That is the solution I had in mind. Just haven't decided yet whether I'll blend in linear or gamma light. Linear light should be better, but it's also more expensive.

I read up on DXVA deinterlacing and it uses the deinterlacing your GPU supports (instead of having a native deinterlacing method). DXVA can even support 3:2 pulldown if it is implemented in the renderer. Imo best feature EVAR!

How can I do this? I have no clue.

There's a file called "activate debug mode.bat" in the madVR folder. It will exchange "madvr.ax" with "madvr [debug].ax". MadVR will now create a log file on your desktop. Zip it and upload it to something like mediafire.

It seems that in your case the scanline data sometimes allows different interpretations (50Hz and 75Hz). I've never heard of such a problem before. This will be hard to fix. Does this occur in windowed and/or fullscreen exclusive mode?
Thanks for the reply and info - It occurs in both. I also run TightVNC server to access the HTPC remotely from a laptop running at 1680x1050@61hz and I am just wondering whether this is causing the scanline data issue. I have just upgraded TightVNC to the latest version to see if this makes any difference and will do some further testing to see if I can isolate the issue.

Try drivers from 2010 like version 10.11
I meant how people hyped it up so much like that, saying how much it would beat the i5 2500k and it was one of the most disappointing things ever and underperformed compared to their Intel counterparts by heaps Well enough of that, this is hardly the place for hardware talk.
