I disagree! I can see the differences mostly in high action scenes like fights or even war movies. But close fights mostly. Ofc landscapes and faces or screenshots like we see on screenshot websites several times doesnt show any differences.

Chroma upscaling isn't affecting the picture as much as you think it is. Action scenes are not the instances where you'll see differences. You should back look through this thread for the comparison posts and screenshot yourself. Sounds like placebo.

You have no idea what you're talking about.

You'll only notice chroma difference in things like red on black texts/backgrounds, and even then the differences are minor.

Depends on the scene, I've seen some quite large brightness changes on some scenes that are mostly mostly red/pink even without SuperRes enabled. Super-xbr 150 I believe is the brightest of them all.

What can be the cause when there are a lot of repeated frames? My render queues are full and stats are around ~25ms. I read here in the thread that the 1809 update to Windows 10 could be the problem, so I rolled back to 1803 (using an older backup image). Same problems. Could it be the newest Nvidia drivers?

Think you'll find it's related to the refresh rate and the content you're running. Show OSD plz.

That seams more likely yes. I do have a new TV btw, so I will look into that

It cracks me up that so many people spend so much time debating/arguing about chroma.

Yes, there are differences between algorithms, but gpu usage is more wisely spent in other areas.

I use Lanczos3 and I don't feel like I'm missing anything. I've compared all the algorithms extensively. It's the least important of all the scaling settings IMO.

IIRC madshi uses Bicubic 60 (the horror).

I am still on Bicubic 75 and SoftCubic 80.

Although, I use Sharpen Complex 2 (post processing) in MPC-HC to bring out details in the picture - it works well with SoftCubic 80.

so he waste time and effort on chroma only scale like reconstruct?

and even if he uses bicubic 60 why should i care and do the same?

So what you are basically saying - as I don't want to misunderstand you - is that when I buy an OLED: If it doesn't have PC Mode, then I want to be using Game Mode?

On the Panasonic TX-55FZ800E, they have arranged it so nicely, that Game Mode can be used on any picture mode.

Any alpha/test builds of madVR Photoshop plugins planned for 2018 or even 2019? They would be SOO awesome! For example, current Photoshop tools that can de-noise well always leave ringing, which in itself, is pretty much noise. MadVR has excellent anti-noise WITH anti-ringing capabilities! I bet madshi could straight up sell madVR Photoshop plugins to Adobe for some $100K+!

This is why it was removed after all and I was a big fan of it up until it was removed.
I'd be curious to see NGU AA (on chroma) low vs medium. I'd like to reduce my settings from medium to low for less fan noise

This is why it was removed for chroma upscaling but not completely. I think there is a good reason to prefer it for image upscaling in some situations as I explained some posts before.
For chroma upscaling I use Super XBR and I don't think I need anything better.

Yeah that's looking good, you could reduce the queues unless for some reason you need them that high.

Partially because it used OpenCL and madshi didn't really want it in madVR any more, but NGU AA was created to replace NNEDI3 and although it's not as sharp it does handle edges better.

You wouldn't notice the difference in motion, what you will find is that the color graduation will be smoother due to more sample points? and I find there is less ringing with higher settings.
Take a look along the edges of the folds of the cloak, especially the color graduation of bottom middle fold.

NGU AA low vs Medium Bear in mind this is enlarged 300%.

The jump from NGU AA low to medium is greater than medium to high, personally I prefer medium as my base quality setting but it's relatively minor at the end of the day. I say change it to low and be happy with the lower noise.

there is a shader version of nnedi3.

Yeap, and if you enable adaptativesharpness by any reason it will be even brightest. Super Xbr is good but the brightness is a problem for me as green is not green anymore. everything green looks like sativa or lettuce. Back to nnedi3 again

Im tempted in returning to Lanczo or Spline with adaptativesharpen enabled. But im not sure.

not what an chroma scaler has to do with adaptive sharpening and you should really read what ryrynz said.

and a chroma scaler will never turn something white is literal impossible.

I had my queue sizes at 8, but I got a lot of dropped frames. That went away when I put them higher. Why that is, I don't know.
