Maybe madVR should disable DXVA for HDR content? Most wouldn't be aware of this limitation.
My 960 2GB wouldn't downscale 4K HDR 60FPS to Full HD even using DXVA for long without stuttering. If I start playing this content will need a 1060 at least. |

Yeah I don't get what's causing it, RAM usage is low (apparently) the GPU utilization isn't high.. but it just can't cope. non HDR 4K 60FPS is fine, I haven't tested many HDR clips but this one stutters almost straight away no matter what I change.

In FSE mode, the "display" stat is wrong so it still stutters. It's as if MadVR isn't detecting the refresh rate change made by other applications - maybe it's being started too early? It'd explain why letting MadVR handle refresh rate changes works fine, even without FSE.

Its a bit of a known limitation that other refresh rate switchers can cause such issues if they don't do the switch before madVR is loaded entirely, otherwise it might not pick it up properly. Using the madVR switcher has certain advantages anyway, the app doesn't have to guess the frame rate, madVR gets told by the video decoder.

if you don't want to use FSE or overlay there is is always a change the composition rate will not match. http://bugs.madshi.net/view.php?id=204 changing the screen will disable the madVR display mode because they are created for that one screen. in your windowed issue you have composition rate issue and in the. in your FSE issue the issue comes from a program whatever that may be... using the wrong refresh rate.

I'm afraid to me this looks like a bug. This happens with 10 bit sources, regardless of HDR encoding or not. This is not an issue with EVR, which must use the same DXVA drivers. If this gets fixed, the next issue would then be the proper HDR -> SDR encoding before RGB output to the 8-bit monitor. Here, EVR color output must be adjusted by the player to get good looking HDR, which is annoying. If madvr could get this right, it would be a win

There is a driver bug that causes wrong colors when getting 10-bit data back from DXVA2 decoding/scaling. madVR is very good at HDR -> SDR and it provides multiple ways to accomplish it. I certainly approve of the quality of madVR's HDR -> SDR and I don't need to fiddle with the settings to get good results. Just don't use DXVA for anything.

I have scripts to enable stereo 3d in nvidia, and I tried using profiles to enable/disable 3d, but it seems running batch files on profile enable is broken? I haven't had any replies to my 3d queries till now, have people completely given up on stereoscopic 3d movies? |

videos may need downscaling now and who knows what the TV does with that input. i highly recommend a custom refreshrate with 3840x2160p23 . and please be aware that getting closer to 23.976 doesn't mean it is getting better. |

Here is a tutorial to improve accuracy of a custom resolution:

Since there is no "OFF" option (or at least one that I can find) for mVR image downscaling, chroma upscaling & image upscaling, can you please tell me which option(s) for these three sharpening functions would most simulate OFF? I am using mVR with a low power GPU on a laptop and am soon going to add in a Darbee to the mix because I need to reduce all the taxing GPU/CPU load I have been putting on my laptops with a projector. But of course I still want to use mVR because of smooth motion and the various other awesome features, so when I add the Darbee I would like to start at a "normal", non mVR sharpening operations (for want of a better term) and increase sharpening slowy step by step up from that point and see how it goes... thanks guys very much

That makes no sense. If madVR changes the size of the video, it should do that in high quality. If you use a low quality upscaling (or even worse, downscaling), information is already lost. A post-processing box can't fully recover that. The best bet is always to use the highest quality as early as you can.

Let's say I was using Haali as my renderer instead of mVR (which I don't want to do just say for comparison sake), which mVR sharpening settings would emulate Haali because I know that using Haali isn't cpu/gpu taxing... Thanks for any further tips... Last edited by andybkma; 14th July 2017 at 10:36. |

I created some profiles and rules for madvr. Now I want to create an extra profile for low quality sources, which I can switch to with a keyboard shortcut.
Is there a way to show the active/chosen profile name in madvr's stats window? If not, will it be integrated in a future version?

MPC-HC suddenly takes 20+seconds to open a file, status is "opening...", it's fine if I don't use MadVR as renderer.
This happened literally over night. I already updated my GPU driver, reinstalled Madvr, installed an older version, reset all settings. Could it be my HDD? Got a gtx 1070 and an i7 6700k |

@ Madshi.
I made an inquiry with AMD regarding their HDR switching method. Apparently you CAN use their API for on-the-fly HDR switching. 'Thanks for the email. We do provide the AMD GPU Services (AGS) library on GPUOpen that ISVs can use to switch HDR displays into HDR mode on-the-fly from their application. This does not rely on the Windows 10 Creators Update “HDR and advanced color” toggle in Display Settings - we’ve supported this since last year from Windows 7 and onwards with the 16.40+ drivers. http://gpuopen.com/gaming-product/am...s-ags-library/ Please be advised that this service request will be permanently closed if you do not reply within 10 days. If more time is needed to respond to my e-mail above, please let me know and I will ensure that this service request remains open for you. In order to update this service request, please respond, leaving the service request reference intact. Best regards, AMD Global Customer Care' |
