We could say the highest upscaling section in madvr surely is a monster, 1080ti basically deals with every games but it can't 100% smoothly run the ultimate upscaling setting at all, not even close. My friend just pre-ordered the 2080ti, but he doesn't think the new card could break the ice, madvr is already another 3DMark...

Yes madVR has some demanding filters for video processing. So what? Some algo’s for video processing even can not be done in realtime at the moment. So please stop posting nonsense ...

We are already very close with the 1080 Ti. My Titan X (Pascal) can run 480p30 -> 4K with NGU AA very high chroma upscaling, debanding & RCA, doubling twice with NGU Sharp very high, upscaling with Jinc, smooth motion, and ED1 dithering. My card is watercooled and overclocked, and I have soldered extra resistors to the current monitoring circuit to double the available power, but madVR didn't go above 120% power too often even before that.

720p -> 4K is harder, I need to use NGU high for the quadrupling step. However, NGU high is a lot faster than very high for a very small difference in quality, a 2080 Ti might be give more headroom but it wouldn't improve quality noticeably for anything <60fps.

Why NGU Very High for chroma? you know that's taboo around here. I actually didn't notice it was you posting this at first haha.

When the time comes for Avisynth/Vapoursynth you guys upscaling 480ish anime are gonna love Awarpsharpen, blows the pants off NGU sharp.
I have a fairly simple script that does wonders for 720 and 480 animated content and you mix that with NGU AA and it's just amazing ^.^

I always use NGU high for chroma when actually watching things.

But the GPU is easily capable of using very high for chroma if desired (chroma upscaling isn't very hard with 480p anyway). I have a lot of headroom with my normal 480p30 settings. I also usually use NGU AA. I don't like Awarpsharpen or NGU Sharp that much, they can change the look of the lines too much. Old SD Anime is supposed to look like old SD Anime.

Using RCA high + NGU AA very high quadrupling can get a little tricky though, sometimes RCA High + NGU Sharp looks better than NGU AA to me (it takes a bit more GPU power too).

Rendering times for 2.40:1 movies are ~17 ms GPU load ~ 42%, for 1.85:1 are ~20 ms GPU load ~ 50%. The question is it really good idea to use error diffusion 1 for dithering, which bumps up the rendering times plus 3-4 ms, or to use ordered dithering?

Difference is minimal but if you got nothing else to spend the available card performance on then I'd use it. ~20 is still on the low side for 24fps.

I've got a question for those of you with AMD crads...

Is there anything I need to know when I want to change my nvidia and use a amd rx480 instead?

I need the more powerful gtx1070 in my gaming rig.

Is 23,976 working with amd? what about hdr switching?

Then I guess, I'll leave error diffusion 1 on, and basically these are my optimal settings for GTX 1050 ti. Will test more to see if there are dropped or delayed frames.

HDR switching is now working with the latest driver but wasnt for a few versions, i'm currently using 18.8.1, seems very stable.

There does seem to be an issue with colour space though which i've logged to AMD. For some reason 23,976 SDR playback can massively overblow colours in some setups, not all, it does it with mine. There is an easy fix though, just callibrate for a BT2020 display in MADVR. This doesnt affect HDR playback or playback at 60hz and may not happen if you put your TV in PC mode, I use BLURAY mode to get access to motion interpolation which isnt available on PC mode on my TV for some reason (2015 LG OLED).

otherwise 23,976 playback is solid, frames skips / repeats are measured in days on my system, even for 3D MVC playback.

You should be able to get NGU high running on the 480 for both upscaling and chroma as its very similar to my RX 580 card.

Ok, sounds good. Thank you! Pc mode only works with 60Hz on my LG Oled, not in 24Hz. But I will give it a try...

Are you on Win 10? Which Version? I am still on 1709 and I don't know if I should update Windows...

Hi sunset1982, I am still using my RX 480 and all works well. I don't use HDR much.

What is the difference in the doubling options:

"...only if any upscaling is needed" and "...always - supersampling"?

@Siso supersampling will always double and then downscale, even if the source definition is equal or higher than the display definition

I see, thank you. So if I upscale 1080p only, I'm good with "...only if any upscaling is needed", right?

"...only if any upscaling is needed" will always double as soon as the source definition is smaller than the display, e.g. if you have a 1920x1080 source and a 2560x1440 display it will still use doubling.

Where "...only if any upscaling is needed" gets problematic is cropped video that almost matches the display resolution, like slightly cropped 1080p on a 1080p display. You usually do not want to double 1440x1046 before downscaling it for a 1920x1080 display.
