Only those who do not have a PC, because the tone mapping performed by madVR is superior to any other consumer device today on the market. And applying the 10bit to SDR material makes no sense |

Then you would be wrong. madVR is used on many PC monitors.

What are you trying to accomplish? With DisplayCal, it takes just a few minutes to calculate the additional LUTs. All you need to do is run a calibration in the native color space ("wide" for the LGs). Once that's done, in the 3D LUT tab you select the color spaces you want to calculate for your individual LUTs. DisplayCal will put them all in the correct slots in madVR, and madVR will automatically pick the correct one for the content you're playing, even for HDR, as long as you're converting and not passing through.

re the colour saturation issue on AMD cards, if you set MADVR to 8bit it fixes it as you know but you lose HDR switch, would a good workaround be for MADSHI to create a force 8 bit toggle switch for all SDR, just for AMD users. This would force 8 bit on all SDR material but leave HDR as 10 bit .
Should be possible?

This is easily achieved with a profile, madshi does not need to be making workarounds for bad drivers that will hopefully be fixed.

Then using an srgb monitor space mode, it's color correct ? If using an A-rgb or p3 space mode, then it's oversaturated ?

Yes, if you set "disable calibration controls for this display" madVR assumes BT.709 (similar to sRGB for our use case).
If you are using P3 set "this display is already calibrated" to DCI-P3. Sadly madVR does not have an Adobe RGB option for "This display is already calibrated" so you need to use another calibration option to get correct colors on an Adobe RGB screen. Adobe RGB is a color space useful for professional print work so in that sense it makes sense to leave it out of video options but there are a lot of Adobe RGB wide gamut displays out there so it would still be nice to have it.

... you mean like adding CRU solely for NVIDIA cards

blocking 10 bit for SDR would be ok if the issue would be present all the time like it was blocked on nvidia because nvidia broke it and there was no except everyone got the problem but as far as i can see it right now that's not the case her.
custom rates is useful for AMD and intel user too and you know that... |

If the 4Khdr material contains a color that's only in p3 space (outside of 709 space). Does hdr_sdr process not clip/map that color to something in the 709 space ?

because madVR can output what ever you want the HDR->SDR doesn't change this.
if an bt2020 SDR file is played madVR will do the "same". i have no clue if the madVR gamut mapping (not HDR related) using a roll of or is clipping or something else and i don't know that for 3D LUT too. i guess it's clipping. |

Yes, that is my question.
How is Madvr mapping the gamut from the P3 colorset embedded in BT2020 down to 709.. Which is why I asked originally, if Madvr 's hdr-sdr process is expecting a certain end colorspace.

H all,
after reading all the post available everywhere in the web i'm really surprise that its seen so little have issue with those SO annoying stuttering with RTX new card. Coming from a simple GTX 1060 with no issues at all i upgrade to RTX 2060 AMP from Zotac and start with the nightmare to be unable to watch smooth playback, so i follow advice from some of your, going to FSE that i have never need to use it before on GTX card, testing all scaling algorithm and getting nothing better, the only improvement but still not ideal its to add with FSE a lower GPU queue, to its minimum and do not present to much frame in advance, it works for some and look like it really depend from the source, on some video it will have a minimal impact or worst not at all, and im taking HD UHD on MKV AND BD ISO M2TS i really start to feel a bit part of the few or even alone with this issue, it look like it work fine for so many of RTX owner, nothing on that in the bug report, i thought that odd. Only have this issue with video and not in game. @madshi if you read this by any luck i know you are very very busy on the render improvement HDR (great work for all the member involved that some brilliant brain storming over there) and also your new project but i'm wonder if that stuttering issue on RTX card is it something that you are willing to take into consideration cause there is something going there with those RTX . Thx. Seriously this make me mad without the vr , stating to think maybe to ask a card replacement is that only last option ? if there is some light there from someone facing that same issue ? sharing some thought please let me know. My Equipements and playback tools: mardvr 0.92.17 MPC HC MPC BE jriver Media 25 ( fse in jriver and HDR on jvc its a pain) I5 8600k 4.20GHZ 32MB RTX2060 1000 watt power su / Panasonic fz800 JVCdla 7900 marantz 7010 Thanks.

I see that you use full 4:4:4 RGB color space at 60hz, maybe that's the problem, and not the AMD drivers. There are very few chains that can manage 4K HDR in full RGB 60hz, let alone 10bit, but it's not an AMD problem Last edited by If6was9; 12th April 2019 at 11:41. |

here you go https://forum.doom9.org/showthread.p...05#post1870305
this help most RTX user. BTW is well known the issue. just hope the next major nvidia driver does something. |
