Yes sure but the chroma and scaling part can be a really heavy burden on the System depending on the actual input and goal but everyone needs to decide this actually himself and MadVR gives those option to decide it but getting this really avg user friendly is a pretty daunting task.


DXVA Chroma = 150W



NGU-Low = 300W




In motion detecting the difference is like impossible, but the consequences are huge and there is nothing that makes aware of them in the GUI there is no indication about Performance and GPU Shader efficiency at all.

So it doesn't surprise me at all that many users actually experience dropped frames overall in some configuration overtasking their system for a very questionable gain.

The small CPU overhead compared to EVR-CP or EVR-Sync is pretty unproblematic as you said at least on Nvidias Driver

and these power consumption number come from what?

even with a titan X it is going to be hard to reach 300 watt...

I bet it's overall system consumption measured by PSU or external power meter.
But high CPU usage with madVR is weird thing. Looks like software decoding.

130W
290W

What my Energy Provider is going to calculate with,not far off actually

And yes total system power still 2x as much is counted with Ngu-Low and the Shader usage also indicates it

Even in Germany power prices aren't so high that you'd have to worry about that, unless your media habits are quiet unhealthy...
And you are not even forced to do NGU chroma for 4k content. Jinc or eben bicubic might be well enough.
DXVA2 scaling and decoding are poison for image quality, we had this several times. If you don't care about quality, then, well, don't.

Yeah i see though madshi did already improvements on the GUI logic Nearest Neighbour and Bilinear seem to be completely avoided and DXVA prefered only after that you can higher the Shader overhead like you wish and also the Ordering is actually in the Overhead order though NEEDi3 falls off somewhat being Compute and behaving differently.

Seeing that Lanczos4 overhead and knowing you get that on Intels GPU for free lets you also wonder why Nvidia isn't moving on.

It's pretty nice at just 140W roughly 10W above DXVA in it's MadVR Shader incarnation.




Ok so if image upscaling is DXVA2

changing chroma upscaling to Nearest Neighbour or Bilinear has no effect and stays on DXVA but if image upscaling is not DXVA2 it can be changed to either, interesting.

300W - what GPU is that with ?

I think I measured about 110W (will check later) base unit - from the wall power meter NGU-High (Xeon 1225v3 + overclocked 1050 Ti)

4k playback is broken for me. GPU usage is at 99% but the card stays at low clock levels. More upsampling just increases render times. 1080 video plays fine. Decoder queue is at 128 but render queue is at 0-2.

It was working fine a couple of days ago. I don't remember for sure but I think it started after new nvidia drivers.

did you change the power settings back to adaptive.

you have to change this with every driver it is simply like that.

Seems to have solved it thanks. I guess they recently added the optimal power default setting, because it wasn't there before.

they change the power setting from adaptive to "optimal" about 6 month ago.

and it is not rare that a driver update reset this option to optimal.

looks like it was doing it the first time for you.

GM204 GTX 970

i tested this heavily now for 4K nothing above Lanczos4 makes really sense here Realtime.

And Lanczos4 Performs also really well on Nvidias Shader Compiler, it shows really great and stable Render times and a visible improvement over Nvidias default DXVA.

So all in all it has a great overall Balance that really works out well

under 5ms most of the times super nice latency




PS: Yes after suspend Refreshrate shifted again to 60

Hi,

I would like to ask a question:

I've tried a 10bit pattern on madvr to understand if my tv supports 10bit output and seems it is.

Activating 10bit output in madvr produces a strange effect on 8bit videos, their colors become over-saturated (exclusive fullscreen 10bit), if i go to windows mode (8bit) they are ok.
The question is: is that normal ? it is not possible to play 8bit content correctly if output is set to 10bit ?
It happens both with mediaportalp and mpc-hc.

thank you for any answer.

that is bot normal and color saturation shouldn't change.

try a level test pattern judge from that result and stick to 8 bit.

In my case I couldn't see any color difference between 3DLut calibration and the factory REC709 calibration. So, in my case, I disabled my 3DLut profile in madvr, as it ate a bit of luminosity overall.

could you please be more specific? what pattern do you suggest to try? do you have a link ? thank you

We are on a trend that mostly every avg Consumer Device now reaches REC 709 pre factory perfect, professional calibrators thus start to concentrate on P3 and above and even P3 is pretty nicely hit for a relatively nice price pre factory, great times

Not only REC 709 Mastering quality reached AVG Consumer but also P3 is pretty fast on that way future content is dictating it it goes pretty fast now

Wow, I did'nt know this topic is dedicated to 3k$+projector members

P3 is not reachable on my cheap projector, as far as I know.
