madVR - high quality video renderer (GPU assisted)

[brazen1]

I'm sure you know much more about this than I do and I don't mind being corrected. From what I gather, Hynix is supplying the memory. It will be GDDR6. The higher end cards will use HBM2. 384 bit. It will be about 45% faster. NVdecode has been present in the 10 series. No one has implemented it in software because the older version of it, CUVID is all developers have to work with. I assume with Volta will come a new video codec SDK for madshi to tinker with using NVdecode.

NVDecode and CUVID is exactly the same thing, they just renamed it for marketing purposes, but the SDK didn't even change at all (short of the name in the documentation) - and there are no advantages over using DXVA2 or D3D11 decoding with madVR.
The decoding hardware in NVIDIA cards hasn't changed fundamentally for quite some time, only extended for new codecs - but they also don't really have to, its fast and works pretty well.

Hi, there are quite a lot of HDR and 10 bit remuxes knocking about now, perfect for KODI DS and MADVR playback, is anyone aware of a windows tool or app you can install, or anything I can use to check to see if my entire pipeline is 10 bit, it should be, my TV is set as 10 bit and I have deep colour set on my TV, my receiver is also capable or passing through 10bit.

I've compared 10 bit with 8 bit SDR rips and I cant see any difference, obviously it could be these were mastered in 8 bit and just upconverted to 10 bit and therefore any banding issues would remain, so I'm looking for a way to really know whether I'm getting any benefit at all from using 10 bit colour on my PC and TV.

I'm hoping something I play play in 10 bit and then 8 bit where I can see a difference is colour banding, something like this:

Check this thread for some attempts at testing full 10-bit output:

In short however, its not always easy to confirm this depending on the screens processing etc, but as long as 10-bit output looks good..

There’s nothing special about Volta. The Titan V is about 30% faster than a 1080 Ti, and that’s when it doesn’t perform worse. The consumer cards we’ll get later this year will be cut down versions so expect worse performance. I think Volta will offer about 20% more performance for the high end card, which is pathetic. 9 series to 10 series was a 50% boost. I guess they don’t have to try anymore since AMD can’t compete.

Volta won’t be game changer, especially not for madvr

@mytbyte and brazen1:
would it help if you could have a look at one of the movie files yourself? I could cut out the first couple of seconds from the movie and upload it somewhere (any suggestion for a suitable location?)?

You can't really extrapolate the consumer/gaming performance of Volta from the Titan V - its architecture is quite different to the consumer cards. GP100 also had a different architecture (different configuration of cores and control logic, and whatnot), it was just never used on any card one could buy.
The Titan V is the first "compute" focused Titan for a long time, basically since the very first Titan.

I fully expect a high-end Volta "Ti" card to actually be faster in gaming then the Titan V.

Well, I just got the IRQ Not less or equal blah blah error again, and that's with FSE disabled and using MadVR 92.10, but this was only upon exiting my media player and not while watching something.

Before the only error I'd get while exiting was the No Execute BSOD.

i'd look at completely stripping out your NVIDA drivers using DDU and then try 285.28.

If that doesnt work, if you have s spare disk run up a quick image to dual boot to test your system hardware, no point doing a full rebuild if something as at fault.

So im better off waiting

Its not only the performance boost but the new technologies might be worth the wait even knowing i really need a gpu with hevc hardware decoding now.

Hello, i am know watching a lot of 4K HDR 10bit content on my 65B7V OLED and I would like to know if I should keep dithering enable (error diffusion or ordered) ? Same question with all the artifact removals options ? Many thanks

[mclingo]

doubt you will see any advantage from HDMI 2.1 for a while and your whole pipeline will need to be 2.1, but its worth waiting to see if the new cards have it, hard to know how much more MADVR grunt these cards will have though, you may even find the current crop gives you enough, I'm happy with NGU sharp medium on my RX550 for image upscale and Lanczos for Chroma upscale, I get a superb picture all round.

if most of what you play is 1080p bluray quality you may not see much difference with higher end processing anyway, but it can be very subjective and also depend on your TV setup and how far away you are sat.

I have an LG OLED 65 inch and I sit about 6 ft away when watching movies...for the sickest experience possible

never disable dithering except for testing.
and select the type of dithering that looks best for you.
if in doubt ordered dithering.

artefact removal is there to well remove artefacts so your content has banding you can use debanding the is the same for HDR.

Well, upload to wetransfer and PM the link

OK thanks. I thought that with 10 bit videos and good it was not necessary anymore.

[Asmodian]

I do have UHD HDR blurays with banding in the source.

Dithering is always good, "necessary" is relative but dithering is fast and nothing is better if you turn it off. Dithering quality is less important at higher bitdepths but still beneficial.

Sorry, this isn't directed at only you but this question gets asked a lot:
NEVER DISABLE DITHERING!

Is the rx 550 you have able to decode 4k hevc 10 bits UHDBlurays without stressing the cpu??

What chroma algo can it handle while playing a 4k movie? Bicubic only or it can go to jinc?

Maybe the RX 560 thats 20$ more will handle a bit more??

I can have a rx560 for about $125 nearby... And then when nvidia volta cards comes i might upgrade or not. Rx 560 must be better than rx550 right?

[huhn]

the rx 550 is a total money robbery. a 560 has nearly double the processing power for little more.

make sure it is a Baffin XT not a Baffin XL. i better not comment more on this topic. i have no good words for this fist into the face of customer.

but if you want to use NGU you are wasting your money with polaris.

Baffin what?? It doesnt say. Its the MSI RADEON RX 560 AERO ITX 4G OC model.

Here is my setup

3rd gen I7
8 gig ram DDR3
250 gig SSD
RX 550
LG OLED EF950 4k
MADVR:
image upscale - NGU sharp medium
chroma upscale - Lanzos
I upscale everything to 2160p on PC.
PC:
desktop 3840x2160p
10 bit 4:2:0


Everything plays fine, no real tax on CPU, I could possibly push it harder with more tweaking but I decided I like the picture quality i'm getting.

I agree the 560 is a better choice, money was super tight at the time I bought this, I could use my GTX 1050 instead but I find my RX for stable on my particular setup, others would disagree and do frequently .

What I would say is that if you arent really into 3D then there really is no point getting an AMD card as it still requires FSE, if you are only playing 2D 4K movies go green.
