device -> "your device name" -> hdr -> passthrough... -> send meta HDR metadata to... -> use Nvidia's private API.

leave windows at defaults.

You mean Nvidia Use Default Color Settings ? in Change Resolution ?

this is about madVR not the nvidia control center.

the HDR SDR conversation takes a lot of processing power but that to be expected but that doesn't mean it is resource hungry.

You can turn the quality down in madVR if you want to, there are a lot of options for the HDR -> SDR conversion and some change the performance a lot.

Shouldn't it work well with default settings?

I think the colors are better with MPC video decoder+EVR-CP

change the HDR brightness settings in madVR.

you can check the nvidia power settings to they shouldn't be at "optimal".

the white details are clearly more clipped on the be conversation.

So basically the most important statistic is MadVR's estimation of a frame repeat/drop every x minutes rather than the raw calculated refresh rate?

Start from the "CVT Reduced Blank" default timing option.

Sadly the most important stat is the reported repeated/dropped frames, even madVR's estimate is not accurate (madshi has stressed this point many times). You have to see what actually happens if you want it perfect, nothing can measure the true clock rates accurately enough.

Hey, ok I understand how to enable HDR.

but performance question.

When watching in Exclusive Full Screen my rendering time MS is very high
Windowed mode works fine.

If I'm using 4K resolution + HDR or without HDR for that matter.

What should I lower so I can watch movies properly ? I watch usually movies and series 1080P and 720P MKV , now I use

Chroma Upscaling NGU AntiAlias- Very High quality
Image Downscaling Jin - Scale in linear light On , activate anti-ringing filter - relax On
Image Upscaling NGU Anti-Alias - Luma doubling Very High all the rest is let madVR decide

which options can I change without affecting the quality of the picture ?

I have
3770K
1080 GTX

Drop back those NGU AA settings.. easy. Did you really need to ask? Is madVR really that hard to configure? =/

I know, I just lowered in the upscaling in dobling . luma doubling to High or Medium. that fixed it.

It's not hard, but I just ask a simple question , you saw how simple was that. Why getting mad ? it's a forum , there are many options , there are many issues. didn't you ever asked a question and you got the same question you gave ? what would you feel...

Always think about what happen when you get the same answer you wanted to give.

Actually, it is for a lot of people, especially new users and people who don't understand video technology very well.

I think madshi has said a few times that making madVR easier to configure is a major priority before he'll do a 1.0 release.

Can anyone help explain why I'm getting dramatically different performance with kodi-dsplayer+madvr vs mpc-hc+madvr ?

kodi-dsplayer+madvr+lavfilters (external) = >50ms rendering time
mpc-hc+madvr+lavfilters (external) = ~15ms rendering time

Same renderer, same settings, same decoder filters.
I have kodi set to NOT manage madvr, so it's the exact same settings as when I close kodi and run mpc-hc (both are x86).

Whats the difference I'm missing here?

Are GPU clocks the same during playback with both of them? Maybe with kodi the GPU is in lower power state for some reason.

Luma doubling quality is more important than chroma upscaling quality. Lower chroma down to medium before lowering the luma doubling quality.

I would assume so, as I've set the power mode in the nvidia control panel to Adaptive instead of power save. However, how would I go on making sure? I can run something like GPU-Z, but how would I know what it shows while playing fullscreen?

Are Kodi's GUI & OSD still available when using madVR? The player's interface rendering might interfere with the video renderer, I know it does with MediaPortal.

They're available by design, but this happens regularly even if I don't have any GUI elements displayed. Either way, I would assume this shouldn't have that kind of dramatic effect on performance. It basically makes it unusable if it's by design like this.
