madVR - high quality video renderer (GPU assisted)

[noee]

You're right, I can only get to med. High pushes it up into the high 40s.

[huhn]

i get about 11 ms with med and i'm talking about the NGU renderstep alone ignoring the other steps.

and don't forget a 960 is about 30% faster card.

MPC-HC/EVR-CP does support XySubFilter. Or do you mean it uses yet another interface?

He uses MPC-BE, which does not, as far as I know. Additionally, LAV Video only uses this interface with madVR, so with any other renderer there would be no conflicts.

[sneaker_ger]

Ah, MPC-BE. I didn't read carefully enough.

[Aleksoid1978]

MPC-BE support XySubFilter long time ago.

trying to understand why my CPU is getting hammered by MADVR, thought the processing happened on the GPU, DXVA hardware decoding and everything on the shaders, the CPU should not be touched surely?

If I use NATIVE instead of COPYBACK the CPU use is halved suggesting some of MADVR's work is happening on the CPU, is this nornal?

I've only got a lowly I5 2400

[huhn]

even with DXVA native i get easily 12 x more CPU usages than EVR. in my eye it is should be investigated.

[dvd1]

how to figure out if the video card GPU is at the limit?

[huhn]

same answer as last time if your AVG rendertimes are over the frame tiems you will drop frames because the GPU can't handle it.

or in short if you drop frames your GPU is usual over it's limited

What video card do you have?
For only monitoring you can use GPU-Z
https://www.techpowerup.com/gpuz/
For tweaking such as changing memory clock and adjusting fans and such there are free software for that, both for AMD or NVIDIA.
I use EVGA Precision which is for NVIDIA GPU's.

Some features run on the CPU: film detection & reverse pulldown; black bars detection; and possibly hdr "measure each frame's peak luminance" but I'm not sure about that last one.
(Edit: and when using native decoding, those features cannot work obviously)

12 times more? How high would that be?

I only get around 2-2.5% with DXVA2n/D3D11VAn, which isn't much more than EVR or the crappy Windows 10 video app.

Copyback modes weirdly show higher CPU usage with madVR than with EVR, especially D3D11VA-CB.

[huhn]

with EVR about 2% at ~1.5 GHZ with madVR about 10-12 @ 3.4 ghz

Very slow? Perhaps a bit slower. Madvr runs fast here on polaris RX 480. Lot faster than in the beginning.

[huhn]

can you please use number...

just to give you an idea a 1060 can do NGU very high for 1080p->UHD with normal chroma.
that's easily 2x of that what a RX 480 can do. that'S has nothing todo with "a bit" slower.

I don't think that is normal or your CPU is really slow.
6700k stays at 800MHz here when using native decoding and balanced energy profile.
With modern CPUs like Skylake or Ryzen it's btw. better to set power profile to maximum performance and let the CPU itself decide the clocking (tools read out full clock then, but that's not true). I have to set C-States to auto for this, checked it with a wattmeter.

I don't have numbers, sorry. There are lots of numbers in game benchmarks. But these do not apply here.

I confirm that the RX 480 cannot do NGU very high.

[huhn]

create a folder with ShowRenderSteps in the madVR folder and you can get numbers.
