As long as the average is below 1/refresh and you don't get dropped or repeated frames, it's fine. The max could be a problem if your buffers / queues are small.

Of course, a 3D LUT cannot react to dynamic metadata, which could be seen as a drawback. So far, I don't think it matters much, though.
using MPC-BE with internal codecs could work as a work around.

madVR should get the bt 2020 information but not the HDR infos and if i'm not mistaken that is what you want.

i will for sure try your new 3D LUT.

Good point, I will try that, thanks.

I'll likely post it in the madVR/Argyll thread on AVSforum when it becomes available. Currently the changes are only in version control.

Is it me or is there no difference between chroma upscaling with super xbr compared to nnedi... my gpu can handle both fine. But i don't see any reason to use up the additional resources. Am I wrong in my assessment?

No, your assessment is accurate. You've discovered how difficult it is to detect changes to the chroma layer.

There are some clips where the difference is more visible, but it's usually really hard to tell, especially in motion. The only reason to use high quality upscaling for chroma is when you have a lot of power left over - chroma usually only has a quarter as many pixels as luma, so high quality upscaling is relatively inexpensive.

Oh, sorry for quoting you on the wrong reply.

At any rate, we both can agree that the thinning is very aggressive, that's totally true! I just happen to enjoy it with a lot of content

NNEDI3 128 does look quite good. 256 looks a tiny bit better, but my 1080 GTX tends to get hot with that setting and the render times are at about 39 ms, which is too close to the frame time of 24p content. Should I lower the setting if the max sometimes hits 45 ms, but the average is around 30 ms? I'd ideally want the max under the 41.7 ms of 24p content?
You're playing FHD content and getting these times?

I imagined that after getting an 1080 I would finally be able to do 4k + NNEDI 256 neurons

As Ver said the differences are extremely minor. Super-xbr is your best bang for buck and the main choice I think for most in the forum as it's relatively inexpensive in comparison to NNEDI3, just make sure to tick anti-ringing.

I wouldn't recommend 256 neurons it's really not worth it, don't let the max render time get that high and accept that extra heat and noise for something you won't even notice.
There's significant diminishing returns past 64 neurons.

My monitor is 1440p, so I can't really test 4K unless I downscale.

Cheers, I'm curious.

That's why I'm pretty much sticking to Jinc for all my scaling needs.

You can't see a difference in sharpness between Jinc and NNEDI3 64 neurons?

I can, but NNEDI3 has more artifacts. It tends to look more processed. Not a huge issue with chroma, but it doesn't look too good with image doubling.

Guys, Check your OSD after installing the Anniversary update as 14393.10 broke NNEDI3 on my GTX 960 and may likely bork other setups too.

NNEDI3 was working fine previously just prior to the update, I simply reinstalled the graphics drivers selecting a clean install and it's working fine now.

Thanks. Yeah, those big updates do tend to break drivers - it's pretty annoying.

It's because the Windows update deletes OpenCL driver. Happens for every big update to Win10.

YES. MY findings:

OK. Here's my fun-times with MAD-VR and 4K + HDR. Running 0.90.23 in MPC-HC with a 12 core XEON and GTX 1080 on an HP DeamColor z32x 4K monitor.

Windowed: like butter. Even with the window nearly the full size of the 4K display. GPU clock :1.8 GHZ, load (with all HDR processing enabled: 75%) No dropped frames decoding 4k60p HDR.

Full screen exclusive: Drops frames like mad with both 4K24 or 4K60. GPU-Z shows the GPU clock is WAY lower at 835Mhz and fully loaded. Unusable. Even dialing back settings, frames still drop.

Really odd.

anyone uses Nvidia DSR with MadVR on MPC-HC with a 1080p display.. is it recommended for 2k or 4k then downscaling to native res?
