I test it with one frame from the movie Howl's Moving Castle (DVD Release). I can upload samples tomorrow.

Thx.

Two examples for chroma s-xbr vs. NGU:

NGU:


s-xbr 100 AR:


With this sample, s-xbr has problems with kind of "inner haloing" or "outer darkening" (how you like to put it).

NGU:


s-xbr 100 AR:


Here s-xbr is quite blurry and there is a lot of dark haloing.

Maybe it's just me but I'm wondering if a lighter value of "soften edges" and also "add grain" could be offered (between off and 1). When scaling very low-resolution content the differences can be fairly visibly substantial. There may be some utility in a smaller nonzero setting.

Still testing but NGU looks great to me so far.

[aufkrawall]

I agree that finer steps for soften edges could be beneficial for some users.
I myself got used to the sharp edges quickly, though.
As long as there is no bloating...

You know the whole thing is blurry right? Not a good test for chroma. Nearly every chroma upscaler has dark haloing and super-xbr is one of the least haloing upscalers along with NNEDI3. When NGU is updated to be guided by luma it probably will do it too. What you're seeing here I think appears beneficial because of the type of content and how poor the resolution is in the same way bilateral would. I'm expecting super-xbr to be eclipsed by NGU for chroma when the upgrade comes.

Just a couple of quick observations on NGU, madshi:

I can easily double 480p and 720p sources at high quality with my GTX 1060, but on 1080p even the "medium" setting gives me about one frame drop per second. I've been using NNEDI3 32 neurons with no problems. So don't get rid of NNEDI3 until a slightly more efficient version of NGU is available.

Also a caution. NGU works great on D3D 9, but I get massive frame drops on everything at both NGU strengths when using D3D 11. This is on Win 10 Anniversary Edition. Not an issue for me, but if people run into the same problem, this is why. Maybe for now you should disable D3D 11 if NGU is in use.

Love the results, though! Great work.

EDIT: 1080p now works with no drops with NGU medium. I just had to turn off SuperRes (which was at 1).

What content? What are your stats? What else you running with NGU?

480p, 720p, 1080p. I changed nothing except turning off D3D11, and then everything works fine with NGU. Could be a bug in NGU, or a Win 10 problem. I doubt if madshi did much (if any) testing on Win 10 build 1607. No idea if the same problem exists on Win 8.1.

I haven't played with it on my 960 yet but try a few earlier driver versions. I'll post my experience with it shortly.

And why would it be better with even blurrier super-xbr?

super-xbr is far from blurry or soft for chroma if using ~100+

NGU looks very nice! I really like NGU High doubling with animated content.

Nvidia Titan X (Pascal) 375.95, Windows 10 x64 14965.rs_prerelease.161104-1700, I also used the test build of madVR (91b). Final resolution 2560x1440.

Default settings except using windowed overlay, ED1 dithering, and a 3DLUT. Chroma upscaling = Bicubic75, Image upscaling = Lanczos3, Image downscaling = Bicubic100. This is total average rendering times without any empty files with funny names.

Titan X (Pascal)

Luma doubling
1920x1080p24 (2038 MHz)
NNEDI3 256 - 28.6 ms
NNEDI3 128 - 16.7 ms
NGU High   - 18.0 ms

1920x1080p24 (1430 MHz)
NNEDI3 64  - 13.8 ms
NNEDI3 32  - 9.9  ms
NGU Med    - 9.7  ms

1280x720p24 (1430 MHz)
NNEDI3 32  - 5.8  ms
NNEDI3 64  - 7.5  ms
NNEDI3 128 - 11.4 ms
NGU High   - 12.0 ms
NGU Med    - 5.6  ms

Luma and Chroma doubling
1280x720p24 (2038 MHz)
NNEDI3 128+128 - 19.5 ms
NGU High+High  - 21.6 ms

Compared to NGU, it of course is.

[ryrynz]

First thoughts on NGU.. Jesus it's sharp. Thins lines more than I like.. I find I have to use a soft scaler like softcubic 50 to tone it down to something that actually looks natural, but I'll play with the edge softening as well and see how I go.

Yeah soften edges is a must for lower resolution animated content I can stick with Jinc when using soften edges.

The question is if I can make things look better than my anime setup current combo, lot's of screenshots tonight I think..

See above comment.

Yeah I figured you had something else running..

I have no issues with D3D11 and NGU on either setting on my 960.


We'll I've reached a conclusion, I won't be replacing NNEDI3 with this at least for animated content. If an option comes around to it being a bit more relaxed in style like NNEDI3 then I'd take another look. The edge smoothing helps and so do some of the softer scalers when used in conjunction with it but it's not enough to improve how it creates lines, it just helps mask the issues.

Yes, NNEDI3 is softer but I can work with that through post processing it doesn't deform lines as much as NGU and is cleaner to boot which to me is far more important than anything else.

Yup.

Does it fix the problem?

for my environment Ctlr+J still doesn't work.

Windows 10
Nvidia GTX860m(optimus)

Me neither, nVidia GTX880m, Windows 8.1.

There is something odd about the fixed file... when unpacking, the RAR wouldn't overwrite files until I clicked yes to remove the archive after unpacking. Very strange never witnessed this before. Maybe the same thing is happening to you? Ctrl+J does work fine on my Windows 10 machine once I figured this out.

Finally, I figured out in which circumstances the OSD will reject to show.

When run mpc-be directly, ctrl-J will show the OSD correctly. However, if I start mpc-be via 'Run with graphics processor' with my GTX880m, the OSD failed to show when ctrl-J pressed.

This is quite weird behavior I never met before. BTW, I do have Optimus with this laptop, if it means something to the developer for debugging.

I unpacked it and then copy and past them to the madvr directory(overwrite).
But't CTRL+J still doesn't work.

Thanks, I will pass that then.

Btw. I tried this new NGU algorithm. Does anybody else notice a high pitching noise coming from the VGA when this algorithm is enabled ? It's like when you are in a game and there is 500+ FPS in the menu.
