AMD, Intel and Nvidia driver issues and last recommended version

[VBB]

Interesting open issue in those new drivers:

Windows 10 Issues - When setting the refresh rate higher than 100Hz, the color format switches from RGB to ycbcr422. [3053990]

[SamuriHL]

Oh joy. I wonder what else they broke. LOL I'll check the HDR stuff later.

[Grimsdyke]

I encountered this problem a few weeks ago when I tried to setup a nice little htpc with an Intel iGPU but also already at 48 Hz and 50 Hz !! Back then I thought that the hardware/driver had problems with CRU.

[huhn]

extremely hard blocking on chromium based webbrowser in close to black details.
even using screenshoot fixes it so does playing it externally in a media player. i have no notice this on my nvidia system else i would not even assume AMD to be related to this issue.

i now have a confirmation with a different user with the same issue.

Hi.
Can someone tell me which is the best Nvidia driver for madVR with hdr passtrough sending metadata to the display?
I tried 442.74: it works fine on hdr but there is stuttering on 23.970 fps. Then I tried all the newer - perfect on 23.970 fps - but there is a bug after hdr playback stops...
None works fine at all?
What about AMD RX5700?
It works better? How are drivers?
Thanks in advance.

[VBB]

For pass-through, most of us have no issues with the latest Nvidia drivers. I'm on 457.30 myself.

Hi. The issue occurs only because I need to set hdr in passtrough - send metadata to the display.
After I stop hdr playback, the gpu continue sending hdr signal.
There is a known remedy?

[chros]

I reported this 2 times already noone replied. @VBB,can you test this? Thanks

[SamuriHL]

I use JRiver as my player and when I exit the player, it returns to SDR mode on all recent drivers.

[chros]

:) Yes this is how it works, but the question is what happens when you don't close the player but fire up an SDR video after an HDR10 one??? :)

[VBB]

It doesn't do that here, but I recall it used to with older drivers. Maybe six months ago or so. Playback stopped and the display would be stuck in HDR mode until you click somewhere with the mouse. Never bothered me enough to roll back. But again, I haven't seen this happen in a long time.

Note: I do have my player set to close after each playback, of course. Will test later with player not set to close.

[SamuriHL]

For me, in JRiver, when I hit stop, it shuts down HDR mode. I also have madvr set up to restore my resolution which probably has something to do with it.

[chros]

:) So the test case: hdr file is playing, you can hit pause or just let it play, then open an sdr video in the same window.

[SamuriHL]

Yes, stays in HDR. "Doctor, it hurts when I hit my hand with a hammer." "Yea, dumbass, don't do that." :D

[chros]

Thanks for the confirmation with rtx card, there is the bug in recent drivers, it started to happen in 442.92 :)

[funderburk]

Well, I'm always using the latest AMD and never had a problem so far.

[SamuriHL]

So given nVidia's extensive track record on fixing such things, we can expect the 3xxx super refresh cards to be out around the same time. LOL

[VBB]

I can confirm your bug now, chros :)

Set player to do nothing after playback stops -> play HDR file -> play SDR file -> TV will switch modes, but SDR content is extremely dark.

[chros]

Thanks guys, that's what I meant in my summary before, that this is nuts. Literally the last driver that is good (not perfect :)) for madvr is the 398.18. And that is 2 and a half years old!!! :D
And when the fix comes they start to FAQ up something else :) And amd drivers are crap, right? :)

[oldpainlesskodi]

Sorry,but for the price of 3090, you will get a much better payoff by upgrading the panel/display....

Just my 2 cents....

[SamuriHL]

The state of drivers is not what we'd call "awesome", no. I mean I'm happy enough with the latest drivers because playback on them is rock solid. HDR with metadata triggers correctly, audio driver finally works correctly, refresh rate is pretty damn stable out of the box.....that's a win in my book given how bad things CAN be with these things.

[chros]

Yes, it always can be worse :)

Unless you already have a best in class display, which if you can splash out on a 3090 I'd think you'd already have.
Plus some of these people would have their own companies and just write it off as an expense.
If you're buying one of these chances are the least of your worries is disposable income.

[Asmodian]

I finally got a 3090 and it is crazy fast for madVR, as expected. I posted in the madVR thread too but I can do 4K -> 8K -> 4K with NGU very high in 26ms at stock clocks, ~1900 MHz. Not that I want to but that is fast!

Using 457.30. HDR seems to work properly with these drivers, I haven't noticed anything else wrong either. Native HDMI 2.1 is great, that adapter was painful.

[oldpainlesskodi]

@ ryrynz - true.

I also got a 3090 and not only is it fast, but I did some power use comparison during Bluray and UHD Bluray playback using the same settings as with my 1080ti, and as expected it uses around 90W less for bluray (290W to 200W at the wall playing Dunkirk upscaled to UHD) and 50W less for UHD bluray (280W to 230W at the wall playing Pacific Rim chapter 2 using pixel shader tonemapping) to get the same quality. It also gives me about 10ms rendering headroom that I can use as I wish (or not). Obviously not the same story at full GPU load... No undervoltage yet, so power use expected to get even better for little performance trade-off.

I didn’t buy the 3090 for madVR use (a 3080 would be more than enough and more appropriate for HTPC use), but it’s nice to have that headroom and be ready to use tensor cores when/if they become exploited by madVR at some point.

All the below is with Win10 Pro x64 20H2. It's still my old i7 rig (details in my sig) as I haven't built my Ryzen rig yet (waiting for the 5950X to arrive).

Re problems (coming from a 1080ti with 442.74), I had, as expected, to reduce the number of frames read ahead to avoid stutter.

It seems to send HDR metadata fine in passthrough (457.30), but if you go to passthrough and go back to Pixel shader, the picture is corrupted and you need to change resolution (or reset GPU or reboot) to resolve. I never had that with my 1080ti, but I was using 442.74 so not sure if it’s the recent driver or the 3090.

I tried to go back to the earliest driver usable for the 3090/80 (456.38) and the last Studio driver (456.71) and it does it too, so I went back to 457.30.

One dropped/repeated frame per hour with the default drivers (no CRU), which is nice. CRU doesn’t seem to make a difference so I’m not using it for now.

As known, you drop out of HDR when right clicking to get the menu during HDR playback in MPC-BE, but you go back to HDR when the menu goes away.

As long as I don’t use passthrough and go back to pixel shader, I don’t have a problem switching between HDR and SDR. I get back to SDR when I return to desktop, which is what I want.

The 3xxx series supports 10bits over HDMI which is a nice addition, but unfortunately for JVC users it doesn’t help with the chroma up sampling issue, so 8bits is still recommended.

There are levels mismatch between SDR and HDR depending on the bit depth used, so you need to test both.

I used RGB Full in driver, full in madVR and full in the JVC and with RGB 8bits at 23p that seemed to work fine for SDR and HDR but I’m going to have to recalibrate as black are crushed a bit in HDR.

These are just first impressions after one evening checking the basics. I’ll post some impressions and basic benchmarks in the other thread when/if I find the time, but this is all I have currently re driver issues.

For JVC users with 3xxx I recommend for now to use 457.30 with RGB 8bits, full/full/full and pixel shader tonemapping. I was using build 113 for these tests. I’ll post back here if this recommendation changes.

For 1080ti (Pascal) users, I still recommend to use 442.74. I was using full/limited/limited but I was only using madVR. I plan to do other things with this 3090 so I need correct levels for desktop work and games.

[videoh]

Thank you for your reports on the 3090, Asmodian and Manni. Wish I could get my hands on one!

[ryrynz]

Wish I could get my hands on one!

So say we all.

[mrmojo666]

Hi guys,

just in case i repost here:
yestrerday i got a rx5700 xt but seems i lost totally deinterlacing capabilities, at the start i thought it was Madvr but even with vmr9 it's the same ..... anyone have similar experience with that card ?
I noticed that before with rx460 i had more option under driver video custom setting, now there is only brightness.
Already tried with DDU


driver 20.9.2
software deconding with software deint is working
any other tip is appreciated
thank you

No idea if there was a workaround in ffmpeg or if it was fixed in AMD driver, but D3D11VA VP9 now works in mpv on Navi. Playback seems to be fine at low power consumption, afaict.

[huhn]

AMD didn't fix it it still doesn't work with lavfilter 74.1 the workaround to ignore the flag that says it can't do it in bitstreaming is still needed.

tested on 2020.10.1

[aufkrawall]

It now also works with regular ffmpeg + ffplay build by gyan.dev though.

[huhn]

and why shouldn't they add the same workaround?

[huhn]

that's been the case since pascal.
they clock far higher than the specs say.

1900 is "low" for the card it's not even trying.

[Klaus1189]

If I compare different cards, i mean different AIB 3080s or 3090s. How do I get the „best“ binned? Or at least better than average?

[huhn]

you don't.

without OC they end up at pretty much the same boost clocks.
a good binned GPU is only useful for OC and without OC testing the card you will not know.

[Klaus1189]

So just get one I can and if that card works, no defect or anything, it will be good? Just a thought: Alternate prices for 6800XT were ridiculus +200 € over MSRP

[huhn]

the 6800 is a paper release just ignore it for the next weeks the real price fight start when demand is delivered. currently nvidia has no reason to lower prices because AMD has to stock.
they a very compative and unlike nvidia perform good at 1440 and show "issues" with UHD. maybe a bandwidth issue so time to see if we see a bandwidth issue or a Vram limitation first.

get a card with a good cooler and good is everything else is out of your hand.

[Klaus1189]

good is everything else is out of your hand.

Sorry, what do you mean by that? :)


I could have gotten a RX 6800XT but for that price - no thank you.

[huhn]

if you get a defect card you get one if it has coil whine like crazy happens.if you want Samsung Vram and not micron for application X it's random and out of your hand.

[el Filou]

Would it be possible to add a note to the first post that hardware deinterlacing is either not working at all (apparently with DXVA2) or if it works (apparently with D3D11VA) it gives very bad quality i.e. not motion adaptive, on Radeon RX 5000 series?

I know deinterlacing isn't used much, but for some people who need it can be an important information.

[huhn]

they are both broken in the complete same way.

want DXVA2 "not" to combine just use DXVA2 scaling for everything and you will get the same low end quality as with the video app because it is doing the same.

i'm testing and reporting on this for like 13 month now.

[Klaus1189]

Of course ;) Which version is first affected?

I got another question to you all if you open taskmanager and look for vram, do you also have stated dedicated VRam of your GPU but also sytem ram that is used for GPU if it is needed? Is that a feature of any kind? I never set it up that way.

I know integrated GPUs in CPUs use system RAM, but I do only have CPU without integrated GPU and a dedicated GPU.

[huhn]

all driver version with no exception.

Is that a feature of any kind? I never set it up that way. Yes I have that on all my machines. Windows 10 allows up to half of system memory to be shared with a discrete GPU.

[Klaus1189]

Does that help in certain circumstances?

[aufkrawall]

and why shouldn't they add the same workaround?
I'd rather assume that it was added in upstream ffmpeg (though I didn't check your claim with upstream LAV Filters), but I can't find a corresponding commit.

The broken Navi deinterlacing is a bummer, though my impression with Polaris was that its quality was crap vs. Intel anyway. Good thing mpv has automatic copyback for yadif by default when enabling deinterlacing.

[chros]

Thanks for the confirmation with rtx card, there is the bug in recent drivers, it started to happen in 442.92 :)
I've sent madshi a pm on avs to let his nvidia contact kmow about this, we will see what happens...
