madVR - high quality video renderer (GPU assisted)

[Sunspark]

You didn't say what you were using, but if you aren't, try putting decoder in D3D11-Automatic and the renderer settings in D3D11. Uncheck exclusive.

[mclingo]

yeah got all that, apart from fse is ticked

[Amuat]

At least one downside of not using exclusive mode is that it takes more resources to render a typical 24 fps video at your default monitor refresh rate (assuming of course it's a typical 60 or 120 Hz or such), which exclusive automatically changes to one corresponding to the video your playing. AFAIK auto-HDR doesn't trigger either without it. But the first one is what makes it a non-option for me, as I really don't have the resources to spare.

As a sidenote, I also experience the freezes mentioned on top of the occasional constant skipping of frames, but I experience those brief freezes during other tasks too, so I don't think it has anything to do with madVR (or MPC-HC) in my case.

FSE does not exist anymore.
if it still would work it would in theory be faster not slower.
it does not change the refreshrate and it can be run at any refreshrate.
the refreshrate doesn't cost performance it only cost performance with present a frame every vsync just stop using it if you can pay for it.

@Amuat Since it's happening with other tasks, a good starting point would be to scan your machine for bad RAM. https://www.memtest86.com/

I'm sorry, I didn't quite catch what you meant by that, could you please clarify a bit?

Oh, I've actually recently upgraded from 8 GB to 32 GB, ran an exhaustive diagnostic test with a Lenovo program that took several days (everything was supposedly fine), reinstalled Windows, upgraded BIOS... I don't know what the hell is wrong with my system. There are no sounds of any overheating either when it happens.

He's saying that FSE doesn't exist in default current configurations of Windows, that you have to take steps to disable the new behaviour in Windows in order for exclusive mode to work again.

Also says that the mode is not related to the refresh rate, it will work at whatever refresh rate your monitor is able to switch to.

Try using a different video renderer like evr custom presenter.

That's exactly what I was saying, it automatically switches the refresh rate to match the video you are watching. Also disabling 'present a frame for every VSync' did absolutely nothing to reduce the performance cost of not using exclusive mode. And if you really need to change some settings for it to work on Windows 11, I must have done that unknowingly, since when I use it the 'device info' option on my OLED really does show that the refresh rate is whatever the video is in, not my native refresh rate. Or then I just don't understand what it means that it's not working by default. Anyway, I will continue using it as it works by my standards.

Windows changed how the desktop compositor works. It has nothing to do with refresh rate.

Exclusive mode does not switch the refresh rate to match the video on a PC. If that is happening, you turned on refresh rate switching in either the player or madvr itself.

Yes, I have the relevant settings set up in both, but the refresh rate change only triggers when entering exclusive mode. I don't know if it's that or something else, but I really do have speedier rendering with exclusive than on regular full screen.

Hi, i'm still getting these dropped (not skipped) frames a couple of times in movies the picture actually hangs for a good second or so but there is nothing in events and usually about 4 frames dropped. I've tried different AMD drivers and also switch to DXVA rendering to no avail, doesnt happen with any other renderers like MPC. Anyone think of anything else to try, its no my processing though as i've tried different settings and i'm only about 20-30ms anyway. Nothing in system or app events either so it has to be something to do with MADVR rendering specifically.

I have bought more ram recently though but I am sure it started a while after that, I dont want to take it out though as my Cooler covers the ram so I have to take it all apart and add new CPU paste every time i replace / move the ram.

Any further suggestions as to the cause, or any diagnostics I can try, ram tests all clean and no others in other apps.

Not the subtlest method, but if it was me, I'd take an hour, swap the SSD and try a nice & clean Windows install on a spare SSD (the old one is used as a backup), with the bare minimum to play a video, just to understand if it's software or hardware related.

I'd probably go Win 11 too, since it's the standard now.

I would like to create 3D LUTs for madvr. I will use madvr with a projector.
Should I create two different 3d luts because my target luminance in SDR is 16 fl, but with HDR (tone map using pixel shader) is the projector's maximum light level, maybe around 40 fl?
Otherwise I know that I should create only one D65, 2.2 gamma, DCI-P3 3D LUT.

Usually, I set madvr and projector to limited range, but the gpu to full range. However, now I have a Declink 4k mini recorder card, which I would like to use to connect some sources to my htpc. In this case should I set madvr, gpu and projector to full range? And waht about the different source devices? They send YUV limited signal, not RGB.

Even easier: use Rufus to create a Windows 2 Go USB flash drive, which you can then boot on without having to "install" Windows per se (similar to a Linux LiveCD). Very handy to verify if a an issue is related to a Windows install.

it would be a lot of messing about and would take a lot long that than as my PC is built into my living room wall, its not super accessible. I was hoping for some advice to what people thought might be causing it.

[Sunspark]

Do the Rufus suggestion. My assumption is that you probably still have a USB port accessible unless it's actually been drywalled off.

You boot from the USB connection using the UEFI boot menu.

Is there a guide on how to control sony projector via madvr ip control function? I would like to change picture modes on the projector based on the input signal.

[TheGameMaster]

My system, on it's own, went from using NGU-Antialias for doubling to super-xbr. And I can't figure out how to fix it. Regardless of doubling setting in settings, it still runs super-xbr. I uninstalled and re-installed everything trying to fix it, an it still does it. If I change it to a non-doubling setting for upscaling it will change to that. But when I change to a doubling setting it always runs super-xbr. Is it a reg setting?

Thanks,

Rodney

A curious observation I made the other night. I have known for awhile now that overlay mode ignores Windows night light, but apparently, it does not ignore f.lux.

F.lux's colour change is passed on to overlay mode. Very interesting. I wonder how this is being achieved.
