Turning D11 off returns to 23ms.

I haven't experienced this neither with v17 nor with 18. Something went wrong on your side.

Windows 8.1 64bits

Madvr v0.88.18 (same problem with 0.88.16)
LAV Filters 0.65 (using DXVA copy back)
Reclock 1.6

Hhmmm strange, I just saw this only in v16b , but it's gone for me with v18 (never saw that before).
What driver and videocard do you have?

I discovered this problem yesterday, I was in madvr 0.88.17.
So I came back to the .16 version but still got the same problem, and .18 did not sovled it.

AMD 7870XT
Driver version : 15.20 (up to date)

A question, does NNEDI doubling works on GPU? Can it be offloaded to CPU? I'm kinda trying to figure out if I can play a SD video on 1080p by means of NNEDI doubling (32 and 16 neurons; for luma and chroma) and lanczos 3 + AR upscale on top in a HD 6000 of an Intel NUC. A report here says not but he could probably by setting 128 neurons or such which would be a waste.

I also just saw super-xbr as a faster alternative, maybe that one can be handled by the iGPU?

Yeah, that doesn't look too good. It's bad that no problems are reported in the OSD, but it still stutters. What happens if you show the madVR seekbar in exclusive mode instead of activating the Ctrl+J OSD? Same stuttering? I suppose you're rendering on the NVidia? What happens if you render on the Intel instead?

It behaves the same way whenever an OSD element is drawn (debug OSD, seekbar, filename, playback time, volume change, etc...) and it still exists in v0.88.18.

My laptop has a mini DisplayPort which is connected directly to the Nvidia GPU so the intel GPU is not involved in the playback. The previous results are with that port.

When I connected my TV to the HDMI port, which is tied to the Intel GPU so the Nvidia CP doesn't even detect an external monitor, I observed strange behavior depending on when I run the media player with the Nvidia GPU or doing everything on the Intel.

1. Run with Nvidia:

Do you see the strange present stats? Also, the 23HZ refresh rate changes depending on which GPU I run the player with. As I said, the TV doesn't show up in the Nvidia CP so no custom resolutions are involved.

2. Run with Intel:

I'd appreciate it If you can shed some light on why this happens.

And yes, the same stuttering happens in all cases but it's much more random on the Intel and happens only a few times in a couple of minutes.

It runs on the GPU, and the CPU would probably be too slow to handle it in realtime at all.

very unlikely!

super xbr is very cheap that may work.

Dogway · 15th July 2015, 11:24

Yeah, just finished running some testings, but super-xbr isn't too very nnedi3 alike IMO. Maybe Lanczos + AR is all there is to it.
I wonder what should be the minimum power a GPU should have for NNEDI3? On my PC it works fine with a 750Ti.

What's the point of lav when it's included in mpc? Just use mpc nightly.

would be nice if someone could update this tool to properly work with mpc-hc x64 (nightly) and LAV filter x64. (sorry for OT)

I think I'm getting crazy.

I am using a GTX660 (driver 353.30), connected to a Pioneer LX-6090 (Kuro 9G). Using madVR and LAV Filters I set up everything to output 10bit. madVR OSD agrees with me. Nvidia control panel allows me to select 12bit color resolution.

Now the thing that's driving me crazy is that once in a while I get, when the TV switches resolution to 24Hz, the info bit in the top corner (this is a TV small info panel on screen) stating 36bit mode. But this happens once in a while and, for the most part, I get the "regular" 1080p info bit, with no 36bit mention. It appears to be totally random. I just started a movie, got the 36 bit thing, recalled the info panel with the proper remote button, again 36 bit. Stopped the movie, restarted it... just 1080p, no 36 bit. NOTHING changed.

This morning I went out and bought a new HDMI cable, high speed and everything (Panasonic cable)... no difference.

Well, I'm overriding only the Video part of the internal lavfilters with the external one: the internal one gave me more GPU usage a while back (e.g. half a year ago, I haven't checked nowdays), don't ask how and why, 'cause I'd think in the opposite way.
(I'm using cuvid in lav video for acceleration.)

Could it be that "image doubling - always" is broken?
It doesn't use NNEDI3 for 1080p -> WQHD here.

Edit: My mistake, stupid Windows Update driver for Windows 10 doesn't include Cuda/OpenCL...

Never-ever use Windows Update drivers for anything other than Windows' native drivers (System Devices, USB Hubs, etc). I still have no idea why Windows updates do not include proper GPU drivers from the manufacturer.

Would Chroma Upscaling also lose meaning if TV is set to output only to 4:2:2? 4:4:4 looks awful on my TV due color luminance issues.

huhn · 15th July 2015, 19:45

yes it is downscaled again same as with 4:2:0 so the benefit from chroma upsampling is way lower on a 4:2:0 or 4.2:2 screen compared to a 4:4:4 screen.

there is no other "official" way to get the newest nvidia driver for windwos 10.

I have a 4:4:4 screen and when I play a bluray I got this :

h264 8bit 4:2:0 -> NV12 8bit 4:2:0

It make sense in a way because the source is 4:2:0 but shouldn't chroma upscaling output in 4:4:4 ?

that what madVR get's as an input the output of madVR is 8 or 10 bit RGB which is 4:4:4

What do you mean by "official"?

Nvidia has been releasing drivers for W10 for a while now.

Thank you, indeed it makes more sense
