madVR - high quality video renderer (GPU assisted)

[Klaus1189]

What player do you use? Please try MPC-BE and configure MPC Audio Renderer

[mclingo]

ive tried KODI DS, KODI DS better build and MPC-HC, all same issue, i'll try BE but I cant see that making any difference

@mclingo:

Have you followed ALL the steps in my last post? It's the only way you will get custom resolutions to work with madVR optimization.

[mclingo]

ill have a go

[mclingo]

Remove all custom resolutions - i removed my custom in MADVR and reset GPU, its now not showing in AMD control panel so they are all gone.

stuck here -

Reset CRU - what do you mean?
open CRU and remove standard timings - from where?


please be clear, i've done this a gazillion times, i just need to get it right once

[QBhd]

In your CRU folder... there is a reset-all.exe... or you can just delete the active and inactive settings for your TV

I have posted the link where to find the standard timings.

but I guess I will do it yet one more time:

[mclingo]

you mean delete the standard resolutions in extension blocks / TV resolutions + HDMI support sections?

[QBhd]

yes... those are the timings that are overriding everything. And be sure to reboot... even after a madVR optimization you need to reboot... restarting the GPU is not a sure thing

QB

EDIT: you just need to delete the 4k ones... like in my images

[mclingo]

i cant set 23.975 in AMD, it just drops to 23.000

[QBhd]

it's tricky... sometimes you have to enter the timings at the bottom first and hit create... then go back in and edit the rest... also be sure to set ALL the values or your 23 resolution may come up as 24

QB

[mclingo]

ok, got everything locked in exactly as in screen shot, but its even worse, now down to under 10 mins

[mclingo]

Getting somewhere now, the timings to start with didn't work for me, I had to push mine to 23,977 in and to get close 23,976 in madvr at the moment I'm showing 3 hours no drops, if this holds I owe you a beer mate. Does this we can no longer rely on solid 23,976 support from amd, it looks like it, wonder if it has anything to do with upcoming very on the way.

[Klaus1189]

My RX 5700XT is solid 23.976, no issue here, also with all other refresh rates. Would by it again. Price is also good, not cheap but adequate

[tp4tissue]

How are you guys achieving these numbers.

If i put in 23.976 in CRU, I only get 23.9755 readout on madvr. Where do I go from here ? I can't input 23.9765 ,

CRU actually reads 23.977 in its table

Does anyone have a good guide for nVidia custom timings?

I am just running stock nVidia 23Hz which gives me 1 frame repeat every 6.5 minutes or so and I would like to try to increase this time I guess to see if I can improve it.

[Klaus1189]

Play a 23 Hz file for at least 10 minutes and create with CRU a custom resolution using a calculated one in madvr

[mclingo]

its really odd some of us AMD users are getting solid timings and some not now, this never used to be the case, I guess at least CRU's work, i'm getting some sense of what NVIDIA users have had to put up with for years.

[Klaus1189]

Do you have more than one tv or monitor connected? Could that also cause issues?

[QBhd]

Don't forget... my custom resolutions that I linked to are only meant to be a starting point. You start there, play a video for 10+ minutes then optimize, reboot, and repeat.

As for 23.976 support with AMD... it's good enough. As I showed with my testing today, it all depends on your output. If I use Direct Sound HDMI, I get no frame drops/repeats expected... If I use Direct Sound to my PCI-e sound card I get repeated frames every 18 minutes... and if I use WASAPI Audio Renderer the repeats go up to 3-4 hours (if it even does the calculation in the first place). And these different values are all out of the box AMD/OS/Standard timings.

Your "issue" has nothing to with 23.976 support. I know this issue very very well... If I was to guess, the OS just wants to use the EDID's "standard timings" above all else. CRU will override this, but it has limitations. For example you can setup a 23Hz timing, but not a 24Hz timing. I watch lots of content across all of the 23, 24, 25, 29, 30, 50, 59, and 60 "Hz" ranges... this is when I was banging my head against the wall for weeks since I could optimize some and not others. I would even get to a point where I would optimize for 24, but it was changing the 23. Or the 23 would use the 24.... it was a frustrating mess trying to optimize.

As I said in my "guide"... it was only desperation that I stumbled upon the heart of the problem... I just started deleting EVERY 4k resolution I could find in the EDID with CRU... not just the extensions, I went full nuclear on all 4k resolutions.... And then I got to a point where the OS and madVR only showed one, the rest were all "missing" modes. But at this stage you can create your own (either in madVR or AMD) and just like that I could optimize all of them. I then went back and reset everything to out of the box, and slowly worked through which timings were the ones that were overriding all... And that's when I made that "guide", especially after tyguy reported the same thing I had been seeing.

So who is to blame? LG for the EDID? The OS for ONLY using the Standard Timings, which cannot be edited since there are no details to edit? AMD for not being able to make their custom timings override the Standard Timings? madVR for not recognizing the difference between a custom resolution and the actual resolution being used? Maybe all of the above? I just know how to fix it through hours and days and weeks of troubleshooting.

just for laughs, i've not lost all HDMI audio, nothing there at all, nothing in control panel like its not even installed, its now my week, i'll probably have to wipe the lot with DDU and start it all again... ffs
