Yeah, I understand. NGU isn't tailored to this sort of content and NNEDI3 does particularly well here. If you ever did another version of this that went a little less towards ground truth then I'd give it a shot, this sort of content needs something a little less aggressive with it's line prediction.

That would certainly help, I could take care of this in my script but that wouldn't solve my main contention with this.

Here's a test build for those of you who still have problems with keyboard shortcuts and NGU not working:

http://madshi.net/madVR91c.rar

Installation instructions:

1) Make sure you're in release mode.
2) Overwrite the files.
3) Activate debug mode.
4) Create a short log file and upload it somewhere for me to look at (don't attach to this forum).

I'll try my luck with D3D11 shaders, maybe that solves the issue.
I'm ready to do some tests. Let me know if I can do some testing for you.

well maybe wait for a working RX 480 driver...

i would down grade to a better driver but i can't remember a driver that doesn't have serious issues and is working with the RX 480.
They bring new beta drivers every week atm, but sadly just optimized for new games instead of bringing a bug free fro multimedia use.

I don't have time right now to try this, but 0.91b doesn't work for me either (keyboard shortcut). 0.90.24 doesn't have this issue. (Optimus system.)

Thanks for the new version!

I did a reset of the Settings and the NGU High render time lowered to 18s with the same Settings as before. Dont know why, but the IQ look better now as before IMO.

It's not supposed to work. It's supposed to create a log file with information that might help me figure out why it's not working...

what does this mean specifically when watching a (non animated) movie? that the algorithm only makes use of half of the picture or picture information so to say? that it is incomplete atm?

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

the install and unistall batch file of that new version dont work for me. when I execute it nothing happens e.g. the black cmd window remains opened without anything happening (admin rights activated). I do have an optimus card.

is there any other way to install this manually? I did regsvr32 madvr.ax and same with madvr64.ax, but in mpc-hc madvr remains not installed in fact. its working fine with 0.90.24 though.

Some chroma upscaling algorithms like Bilateral and Reconstruction use the luma channel, which has twice the horizontal and vertical resolution, to guide the way they upscale the chroma channel. This can be very helpful when there's a lot of overlap between the chroma and the luma (e.g. if a change in color is usually accompanied by a change in brightness), but it can also lead to artifacts where they don't match well enough. NGU for chroma upscaling doesn't make use of this technique yet.

Here is my smart log download link.

In debug mode ,when I press CTRL+J it shows the OSD.
But NGU doesn't work.

Thanks. Are you an Optimus user? Or are you running any external software like FRAPS, f.lux, GpuZ or Reclock which might access the GPU, too?

How does the speed compare to older methods? Is it slower than anything? Or between some of the old ones?

However, texture detail which is lost during downscaling cannot properly be restored. This can lead to "cartoon" type images when upscaling by large factors with full sharpness, because the edges will be very sharp, but there's no texture detail.
I don't like these add noise "enhancements". Which reminds me:

So what if the movie is essentially (perceptually) grainless? (Which will be more-and-more common as movie digital cameras get better)
Then this will add a grainy halo. Wouldn't a de-grain filter be more useful? (for actually grainy movies)
It would be nice to optionally disable at least.

yse,I'm an Optimus user.
But none for the others.
Also I didn't met the same problem before 0.91.0.

GTX 1080 user - NGU doesn't pull more than 90W of GPU, it's almost as if it doesn't access all of GPU power.

How do I explain it... With NNEDI 256 and im doubling I can pull 210W from GTX 1080, but with NGU the render time grows to ~60 ms, and the GPU just doesn't get more usage, tested powers and usage / frequency using HWiNFO

As it looks right now, there's also a problem with routing the usage of GPU clocks. The GPU stays at low power even with NGU set to high in both Chroma and IMG doubling.

I tried a few different configurations and situations, running Nvidia Driver 373.06, the latest stable Nvidia driver.

Seems that no app, nothing can flag NGU to use the GPU properly. On a similar note, NNEDI 256 will start dropping frames before hitting 100% GPU core, but NGU doesn't reach 40% of GPU core usage.

I don't use FRAP, f.lux, GPUZ, Reclock or other software that might access the GPU, but I have no iGPU installed (Clevo P775 disables iGPU entirely, no Optimus, no tricks).

Are you using the "ShowRenderSteps" empty file hack?

Im on win7x64, I had the shortcut problem with the official but but the first fix you did fixed the issue for me (madVR91b).

Yes, I was.

Totally forgot that it was on and it might affect it.

Cleared it out, tested, 230W max power pull on GPU, max OC clocks achieved.

Nice job!

The visuals are amazing, so much sharpness. At first I almost through why do we have an edge softening algorithm, now I get it

Now time to fix my setup and settings, because my actual settings add blur and over sharpening over certain edges...

Something I noticed recently, whenever I play a really low resolution video (under 720P) there is an audible feedback coming from the GPU, like a high pitched sound, which is not related to the fan. No idea what it is...
