the new amd rt5700xt support 3d frame packed playback for now. But if they will follow nvidia and remove support for 3d, nobody knows

Excellent, thanks!

It would be nice if they supported it in the future - once our cards break we're going to be scanning ebay for used ones. Even with stand alone players this will be the case.

Worst comes to worst ... can tell MadVR to output in Top/Bottom format ... then can tell TV to output 3D in Top/Bottom

if you use 4K LG OLED ... this should not result in any resolution loss

downside ... cannot watch 3d rips in 2d (as switching tv to 2d will show you top/bottom picture) ... solution - create symbolic link to your 3d rip ... name one mkv another mk3d ... then use madvr profiles to output one in top/bottom and another in 2d

plus side to this ... you using madvr to do chroma upscaling and horizontal stetching in 4k for 3d ... and for 2d you also using madvr for upscaling to 4k

Thank you for the link. It sort of helps, maybe. If someone could point me to the custom timings thread. And if you could maybe explain to me in a little more lamens terms.

Neat idea - didn't realise the LG would do SBS at 4k - just tried it now and it enabled the mode. We don't then need 3D frame packing! Fantastic

Don’t do SBS (side by side) ... do OU (over/under aka top/bottom) ... 2 reasons:

1. Most players will overlay their play control on top or on bottom of entire screen ... when watching this on SBS in 3D it will be garbage ... but on OU it’s passable (control will be vertically stretch and only one eye will see it)

2. For LG OLED ... it polarizes horizontal lines for 3D ... so one line for left eye next line for right eye (you can see it if you don’t put 3D glasses ... the image will look like interlaced video) ... so for OU, OLED just alternate over and under lines without performing any scaling ... for SBS, OLED will have to discard every other vertical line scaled by MadVR and then stretch it across the screen (basically waisting MadVR scaling)

PS. AMD ditch their support for frame pack 3D in drivers years before NVidia

PSS. Those who upgraded to 1903 will likely need to upgrade their NVidia drivers and loose 3D frame pack to fix 1903 problems

AMD cards still support frame packed 3D, what support are you referring to?

hmmm ... i distinctly remember searching if AMD still supported HD3D after NVidia ditch 3D Vision from newer drivers ... was going to jump camps from NVidia to AMD just for this

read somewhere that HD3D was no more included in AMD latest drivers and gave up ... and lock my 1070 on last driver that supported 3D Vision

for the love of god ... cannot find where i read it from ... so my apologies if i was wrong ... AMD boys and girls can confirm if latest AMD drivers support HD3D as i have no AMD GPU (if it does ... then next upgrade for GPU will be AMD for me)

While Over/Under trick is nice to have in case all GPU drop 3D ... i i still prefer outputting 3D in framepack as switching between viewing 3D and 2D is nice and easy

PS. Does hd3d works straight away with madVR ... read somewhere that needs 3rd party software to actually use HD3D ... TriDef seems to be preference for AMD users ... but TriDef seems out of buesiness ... any other alternative to TriDef ... will be no good if I buy AMD with HD3D but then cannot use it

because 3DHD is pretty much dead it was never alive.
but madVR uses the OS 3D API not some middle ware stuff so 3D on AMD just works for now.

3D on nvidia still works BTW. but will clearly not going to run after this try to make it work in madVR i leave that to user of 3D.

Hello everyone, I'm looking for your thoughts on this scenario.

CPU: FX-8350
RAM: 8GB DDR3 1866 CL 7
GPU: R9 270X 2GB
No hardware decoding
HDMI 1.3 output

In your expert opinions, Is it possible to play 4K HDR Bluray remux using madVR?

QB

HDR tone mapping would push the GPU to its limits, but it's doable with 'scale chroma separately to save performance' enabled. You'll probably have to set conservative queue sizes to stay under the 2 GB VRAM limit.

You can test the decoding with this: http://jell.yfish.us/ Use the 120-mbps-4k-uhd-hevc-10bit.mkv
Mind you, UHD Blu-rays don't reach such high average bitrates, it's a worst case test with max bitrate.

Same problem. Same solution.

Interesting thoughts... I'll explain why I want thoughts on this setup once I get more thoughts from you guys... Basically I want to see if my pre-conceptions match all of yours and solve a riddle that has been bugging me for weeks now

Sorry to be coy, but I don't want to pollute everyone's opinions.

looks like the 5700 XT is doing fantastic for NGU.
NGU very high 23 ms for doubling while idling at 350-1400 mhz
50-250 watt so don't take these number seriously.

i do a better test later.

edit:
asmodians 240 hz test doesn't work properly it is batch dropping and the video freezes for more then a sec.
i got ~21000 when the driver didn't crash.

the card can do
NGU aa very high chroma
image doubling NGU sharp very high plus chroma mid all together in ~33 ms

and for what ever reason it doesn't like to buffer the display rate is unstable:
https://abload.de/img/rx57000xts1k7t.png

BTW. my version is very loud.
the redeon setting thingy totally bugged out i'm done for now.

The 23ms sounds impressive, but the very loud part less so... Unlike an RTX card, at least you don't have to worry about possible stuttering during video playback with the present queue set to anything higher than 1.

@ Hunn,

Yeah, I'm pairing mine with a Ryzen 7 3700x, and a PCIE 4.0 mobo and 16gig of 3200 hrz DDR4 - will be here all and set up tomorrow.

madshi released a bunch of envy information this morning. One of the things he CONFIRMED is that madvr development will not stop, a commercial version of the software will be coming at some point, but a free version will remain. So that's good!

@ mclingo2 - it's ok, unless you use wattman to auto overclock, but TBH, I have not found a need to overclock.
