Based on feedback that how amazing madVR tone mapping is, I've chosen a Non-HDR display at a very good price.

I noticed something little strange today, using NGU AA low for chroma, and image doubling with NGU Sharp medium, the render queue stays most of the time 7-8/8, but sometimes it shows 6-7/8. I'm using 3440x1440p display, the card is gtx 1050 ti. Rendering times are ~ 21 ms.

As long as you don't actually get any dropped frames, fluctuations in the queue are just normal operation.

Hi, There is a bug for all 5700 users at the moment, AMD HDR API is broken and not sendin BT2020 colour space to HDR tv's, this is likely why you are seeing unsaturated colours?

Turn on windows HDR, then Switch to passthrough and untick meta data in MADVR and have another look, can you report back what your see.

thanks

after 7 years of excellent work my intel 2700k is finally going out to pasture (ebay) - i'm upgrading to a ryzen 5 3600, however i'm sure i've heard some issues about ryzen and video output / madvr etc, anyone know of any issues I need to be wary of with MADVR?

the slightly unsaturated colors are due to the COMPROMISE ON HDR TONE & GAMUT MAPPING function, which I repeat is forced to click to take advantage of the madvr tone mapping at 60hz .... with the PASSTHROUGH HDR I do not need to click on COMPROMISE ON HDR ... . for 60hz and the colors are correct, even using the Windows API.
The only difference I found between the AMD and the Windows API is that the latter is brighter .... but I always use Madvr tone mapping for 23.976 and 24hz, the vision is better with the addition also of a calibration in SDR DCI-P3

the trade for quality option has no effect on path through.
the point of path through it that the image is not touched and you get different results depending on the API which shows there is clearly an issue.

Don't know if they are that similar, but I have no issues using Ryzen 7 3700x, obviously with a discrete GPU.

why should a CPU create issues with video output?
that's not how it works.
it's not effect the video driver in any way it is not effecting the video output in any way.

I just thought I'd read somewhere there was an issue, glad to be wrong.

that TRADE QUALITY FOR PERFORMANCE option, has no effect on the hdr passthrough I also know for what I have specified that I have used it for the tone mapping of madvr

What mclingo meant is that there is/was (?) a bug affecting RX 5700 users, where if madVR itself switches the card to HDR mode, it then outputs Bt.709 colour space instead of Bt.2020, so the image is seriously (not slightly) undersaturated.
If you did not encounter this issue when you used passthrough and let madVR do the switch then it means something is different on your RX 5700 system, or the bug has been fixed.

The bug is still there in the latest 20.1.2 drivers.

Minor fix:
It then outputs Bt.709 colour space flag instead of Bt.2020, so the image is seriously (not slightly) undersaturated. If on your TV you can forcefully select BT.2020 color space, then the image will be normal.
AMD APU with Vega iGPU has same issue.

Yes, that looks like what I would expect from that bug.

Man!
On a Plex media group on Facebook...
People trying to tell me their Firestick is a better renderer than a decent HTPC with MadVR/LAV upscaling, etc played thru Jriver MC or equivalent....
Some people's kids...

I would say a too much rough representation. In reality is not so scary.
