It was an example, I don't know if it's possible to make it sharper without destroying the picture.

Of course not. "Sharpness" can only exist in an original picture. Every other attempt to filter a soft image only increases contrasts, but restoring or even creating originally lost sharpness is impossible. For reasons, see Wikipedia: Gibbs phenomenon, plus try to imagine how to discover which summands were added to a sum, how many valid results this question may have (as results of any scaling are all weighted sums). The best one can try is limiting annoying side effects like the mentioned "ringing artifacts", but the result may still be an artificial "plastic" look.

Hello.
Not specifically related to madvr, but maybe I will get answer without creation of separate topic.
I failed to find any similar issue with google and forum search.

I have a problem with chroma shift 0.5 pixel to right and 0.5 pixel to bottom on any 4:2:0 video any player any renderer when my monitor is connected to my NVIDIA 1060 (driver 388.59, not the freshest at the moment).
At the same time my old integrated Intel HD3000 doesn't have such an issue.
Here are some illustrations for horizontal shift:
V plane, taken in avspmod, doubled in size:
1) as it is in the original video
2) as it is shown by Intel graphics
3) as it is shown by Nvidia graphics

Ultrazoomed example

Win7, Version of madvr 0.91.11, default chroma scaling but I think it doesn't matter as far as it is the same issue for other programs.
Please help or say where should I go. Thanks.

Are you using any DXVA scaling options? This is a known issues with Nvidia's DXVA scaling.

Changing the video decoding method might also help.

Switching to DXVA (copy-back) in LAV decoder fixed the issue.
Thank you, guys Warner306, Asmodian.

DXVA2 (native) - the default value, if I am not mistaken.

Is it true your new algo will be a SVP killer?
FSRCNNX is already sharper than NGU-AA, the SSIM variant is even more sharper.
Everybody knows the madshi's new algo is a motion interpolation one.

That would make sense. It is known to do that.

Great. Some screenshots would be nice. I'm just picturing you looking cross-eyed at the screen trying to figure out which image looks the sharpest. We're always glad when you stop by to share your observations, though.

I really don't. Has he mentioned it elsewhere? I cannot recall he elaborate more on this in this thread.

Never trust someone who asks for a new version regularly or calls project dead.

I tested latest Nvidia 398.36 drivers.
23.976 without any custom mode, default:


It's better then before(~23.971).

looking at upgrading my lowly RX 4GB 460 to 570/480/580 - would 4GB be fully adequate or is there any advantage in MADVR for 8GB ram?

Yea, the latest set of nVidia drivers definitely has improved things and made movies watchable now. Which is great. Is it perfect? No. But it's better.

4GB seems to be plenty right now...

Nice one thanks, just picked up an 4GB RX 580 for 160, nice to see GFX cards coming back down to sensible prices, hoping to maybe get NGU sharp medium or even hight at least on this, I know polaris is a bit pants with MADVR but just too many issues with NVIDIA right now, AMD have their own issues too but I have workarounds for all of them.

@madshi: What exactly is causing not any single optimized pixel clock (regardless of what high estimated compatibility it has) not being accepted by the GPU driver? Is it a problem specific to Windows 10 due to a api change or a GPU driver related one?

It it easy for you to fix?
