latest FSRCNNX32
NGU Sharp - High
NGU Sharp - Very High

To make things as fair as possible I've downscaled the image with Bicubic/Catrom, which is exactly what FSRCNN and FSRCNNX were trained for.

Here are benchmark numbers, for 720p doubling:

Nvidia 1070:
FSRCNN16: 15.270 ms
FSRCNNX16: 26.397 ms
FSRCNN32: 46.290 ms
FSRCNNX32: ? (estimated: 80.021 ms)
NGU-Sharp High: 3.940 ms
NGU-Sharp Very High: 11.800 ms

AMD 560:
FSRCNN16: 14.289 ms
FSRCNNX16: 24.412 ms
FSRCNN32: 45.235 ms
FSRCNNX32: ? (estimated: 77.282 ms)
NGU-Sharp High: 12.970 ms
NGU-Sharp Very High: 37.100 ms

These are very weird benchmark results, to say the least. We know that NGU doesn't run as well as it should on AMD Polaris GPUs. But FSRCNN(X) running (ever so slighty) faster on my AMD 560 than on my Nvidia 1070 is just plain weird.

Look well, very expect NGU can be used at AviSynth also can NGU use for Deinterlacers to replace nnedi3(QTGMC)?

Not yet, NGU is currently only in madVR.

on W10 suddenly there is tearing in Full Screen mode, even with Exclusive Mode enabled. Doesnt happen with EVR (Potplayer) or VLC.
If I disable DX11 renderer in Madvr and switch to Fullscreen, screen becomes black with sound on the background. Player freezes and I have to kill the app via taskmanager.
Using Nvidia gtx1060 and gsync monitor

I even clean reinstalled the drivers

People managing to get 10bit / 12 bit on FULL RGB 4:4:4, are you using monitors rather than TV/HDMI/ Receivers?, when I choose 4:4:4 full RGB I lose both the 12 bit and 10 bit options in my AMD control Panel suggesting its just not possible to get 10/12 BIT FULL RGB on current HDMI specs.

With Windows 10 you need to use 385.28. Select 4K23p, 12bits, RGB full, 4:4:4, apply. Then if the content goes above 30p, the driver will automatically switch to 4K60p 8bits 4:4:4, which is what you want. It doesn't work the other way around.

No idea about AMD, for nVidia see above. I'm using a JVC projector and have no issue to get what's in my sig, at least at 23-30p.

My TV is a 10 bit panel but I can only select 10bit in 420 mode, when I put my TV in 444 full RGB 10bit is missing.

Although i've not tried it for a while and there have been a few firmware updates, might try it again.

I don't think this topic was particularly relevant for you since you know exactly what your video pipeline is doing.

By "I don't want to dither if I don't have to", I assume you mean "dither further than I have to", since you'll need to dither down to 10bit from MadVR's higher internal representation.
But it's those kinds of wordings that made me bring this topic up in the first place. If someone were to assume "10bits, great. Just like my input" as the take away message, they could be dithering more than needed because something in their pipeline downconverted along the way.

It was more a cautionary mention rather than "everyone needs to not do this", but I think it got a little muddled along the way. Oops.

Your TV might have a 10.2gb HDMI max bandwidth, or your cables might not be good enough to pass through more than that. Make sure you select 23p when trying any chroma/bit depth combination, in order to make sure you don't cause a bandwidth issue (or at least you limit it).

I wonder if something is getting lost in translation here. I'm saying that I cant get 4:4:4 FULL RGB 60hz 10bit, pretty sure this is unsupported with HDMI 2.0ab/b, this will only be possible with HDMI 2.1

I havent tried dropping to 23/24 hz as I wouldnt operate my desktop at that.

[clsid]

UHD 4:4:4 60Hz 10bit requires HDMI 2.1
With HDMI 2.0 the maximum is 30 Hz for UHD 4:4:4 10bit.

You didn't specify 60p in your post. That's beyond HDMI 2.0a. You need HDMI 2.1 for that. So why are you wondering why you can't get it, if you know that 4K60p 4:4:4 10bits is beyond your HDMI bandwidth?

[mclingo]

how are you managing this then, is your desktop set to 420 60hz and you have script or something to drop it into 444 fulll RGB before you play a movie, or do you have to change it manually every time?

One way to work around this is to manually change the refresh rate to 30 or 24 in the Nvidia control panel. Save it and then change the bit rate to 12. Save again. Then change back to your normal setting. When you launch an appropriate video, the nvidia driver should switch to 12 bit.

With nVidia (using 385.28 if Windows 10), as explained many times, you select in the nVidia CP 4K23p (apply), then you select RGB Full 4:4:4 12bits (apply). That's it. Then if the content needs more than 18Gb/s bandwidth in 12bits (say you play 4K60p content), the driver switches automatically to 4K60p RGB Full 8bits 4:4:4, and back to 12bits when the playback is over. There is no need for a script. But it doesn't work the other way around. If you are in 4K60p when you select the bandwidth, then you CAN'T select 12bits, you're limited to 8bits, simply because it's not possible to select more than 8bits in 4K60p 4:4:4.

pretty sure that isnt going to work on an AMD card, will give it a go though, think i'll just get a black screen.

[Goeggel]

Sorry if my question has already been answered somewhere else, but I haven't found out yet whether my issue is expected behaviour or whether it is an issue at all.

My setup:
Windows 10 Enterprise 1709 64bit
Zoom Player 14
madVR v0.92.10
Nvidia GTX 980 385.69
Marantz SR6011 AV receiver (HDR ready)
Sony XD9305 TV (HDR ready) -> manually set into HDR mode (BT.2020)

When I play HDR content on the PC through the receiver to the TV (for example the Exodus UHD_HDR_24p.mp4 demo trailer), HDR seems to be fine. Colours seem fine to me at least.

However when checking the info screen with CTRL+J, it shows the source as being 10 bit, but output is "D3D11 exclusive 8 bit".

Shouldn't I be seeing "D3D11 exclusive 10 bit" as my whole chain in theory is 10 bit ready? Or is this because of the infamous Nvidia driver or Falls Creator issue?
Any way to get 10 bit output?

[huhn]

to send 10 bit to the GPU driver you have to set your display to 10 bit.

[petran79]

An issue with Madvr:

If I disable DX11 and set video to full screen, screen becomes black and cursor blinks. I have to kill the app. Problem is that if I restart the app, video acceleration is disabled, even if I enable DX11 again. CPU reaches 90% usage. Have to restart Windows.
