madVR - high quality video renderer (GPU assisted)

[Rittberg]

Hello,
My system Win 10 x64 , with RTX 4070 super , projecting the image to Sony VPL-XW 7000es.
In order to watch 4K HDR materials I am using the MPC – HC + MadVr ,
The MadVr is calibrated according to the guide in the following link:
https://nicko88.com/misc/madVR settings/
I find that with the above-mentioned calibration selecting “tone map HDR using pixel shaders” in MadVr – dark scene looks excellent.
But when selecting – “Passthrough HDR to display” the darks scene looks with less details but from the other side the all picture is more vibrant.
Is there a way to select “tone map HDR using pixel shaders” option, and to keep the vibrant picture?

Thanks for any Idea .

stuttering is driving me crazy! I have windows 11, tried vsync in gpu, power adaptive, high performance in windows, frames in advance to 1 and 3. nothing is working. It was working fine until I had to replace my m.3 drive.

Have you turned off 'Hardware Accelerated GPU Scheduling'?

[toki]

It's off in mpc-hc. I have it on dxva2 (native)

[Asmodian]

It is a Windows setting.

For Windows 11 it is in System -> Display -> Graphics -> Advanced graphics settings.

so the advanced graphics section kept crashing everytime I tried opening it, ran scans, now it's open, turned off acceleration. Now testing. Will report back... Turning it off seems to have fixed it. Now I'm afraid to update graphics driver, lol. Thanks for the help

ok, it didn't fix it, still doing it

Same for me, Disabling HAGS doesnt fix it! I have also tried MPCVR but the stutter (presentation glitch) issues seem decoder independent as that renderer gives the same glitches on Win 11 24H2.

I had to revert to windows 11 23H2, that is the only way to fix it.

Hope either MadVR gets patched, NVdia fixes their driver OR M$fT fixes its shitty OS.

Fingers crossed..

You guys don't have to use Windows 11.. 10 will still be receiving updates to 2032.

Also disable low latency mode in driver settings.

you can also install the newest beta it will not show gliches anymore at least for me the counter isn't there anymore.

Hi!

Is the HDR rendering supposed to be this obnoxiously resource intensive? At first I couldn't figure out why the GPU usage goes so high, went to nearest neighbour on chroma upscaling and such.
But it turns out it's the HDR tone mapping using pixel shaders. It prevents me from having a smooth playback with UHD files.
If I disable it GPU usage drops to like tenth of what it was. But then of course I can't watch the HDR files.

trade quality for performance yes it is supposed to be like that.

Which option makes the most sense to be traded?
"compromise on HDR luminance channel quality" seems to free up the most performance. "don't measure HDR frame peak luminance" is barely noticeable. "compromise on HDR tone & gamut mapping accuracy" is somewhere in the middle.

[huhn]

you are asking the wrong person.
i barely experimented with that.
if i remeber corectly "compromise on HDR luminance channel quality" does barely anything positive negative while "compromise on HDR tone & gamut mapping accuracy" is day night. "don't measure HDR frame peak luminance" sounds like it is the most important thing if it comes to DTM without it you are just TM...

which beta? Measure 207? for me there are still glitches with that one. (on win11 24H2)

[huhn]

beta 208

Quick question if anyone can answer, I'm too lazy to pull my gear out to test:

So long as MadVR is passing metadata to the display, does it matter if Windows HDR is on? Watching a little bit of content on my C1, I don't see any concerns, but I haven't tested extensively.

[huhn]

just a different API that's it.
it is usually preferred not to use HDR toggled on in windows with madVR and let the other API take over.

please don't use this "logic" for a lack of a better word for other software or games where this is different. Microsoft wants user to use windows HDR for HDR.
