Clearly, highlight recovery comes first..

It's just as he's always said, buy the best card you can afford. ^_^ Performance wise it's Nvidia over AMD.

where that is true, with amd cards being so cheap its hard to know how close they are price vs performance, do you get mid range nvidia or a high end amd, its not that simple anymore unless money is no object.

I thought madshi ran ATI, what does Nvidia boards have that madvr makes better use of..

Something about NGU runs much better on Nvidia GPUs...

I just bought a used rx 580 $135, after the amd vega 7 announcement.

Since they haven't announced any mid-range product, there's nothing to hold out for this year.. Might as well get in on the Used Miner cards while they're still available.

the price differenve of a used 1060 and a used RX 580 is 30-40 bucks. and the performance difference using NGU and only NGU related scaler is about 100%-200% faster in favour of nvidia.

he said a year or longer ago that he had a 1070 and a 560 or 460.

pretty sure he has a RTX cards now to play around with the tensor core.

I have a 1060 in my kitchen pc..

The used 1060 on ebay looked slightly more raggedy than the used 580, so I went with 580.. This is for my basement pc.

i'm guessing MADVR is generally more optimized for NVIDIA, it certainly feels that way and MADSHI has closer links with NVIDIA. It would be nice if he could take another look at polaris and see if he can do anything with it, given the number of AMD ex mining cards out there getting snapped up and great prices,

But I'm guessing his radar is already pretty full.

the market share of polaris cards is close to none existing and this will not change.
https://store.steampowered.com/hwsur...lcome-to-Steam

and NGU runs great on none polaris card so how can he optimize for nvidia all run the same shader.

nnedi3 runs faster on AMD so he optimizes more for AMD? what is this reasoning...

If none of huhn's recommandations work, you can also try an older driver that still works with your newer card, or file a bug report with AMD.

Another trick: if you use your HTPC mostly for video, you can set your desktop at 720p and configure the media player to switch to 1080, then in the Radeon control panel you configure 720p with 3% underscan and 1080 with 0%. You'll still have the issue with GUI elements at the edges being cropped in MPC-HC, but it's a lesser problem than having the desktop GUI cropped IMHO.

using a gamma processing option to get mathematical incorrect results is totally fine by me it' the users choice even if it is just used for the same reason we use different gammas for SDR to make dark part better visible for example.
I'm not sure going from 2.40 to 2.20 or 2.20 to 2.40 at the display is ruining HDR. Either way, it doesn't look half bad. I got the best results with 2.40. I can only relate my own experience.

which probe are you using. My i1d3 works well, but my spyder5 messes up dark tones and causes crush.
I got similar results with two different displays when changing the gamma settings at the display and madVR. It could be some deficiency of the gamma tracking near-black, but who knows. They don't crush black with SDR content.

Same for me, as I said before.
Yesterday I checked 2.4 gamma with black and white clipping of hdr10 test patterns, again, and there's no issue at all.

Yeah but thats steam, those figures are going to be massively skewed toward gamers, you cant call that "the market share", Most HTPC owners could own AMD cards, we just dont know.

NVIDIA cards arent just a bit faster according to some, they decimate AMD in NGU, surely further optimization is required, got to be a reason for this?

the reason should be an architectural difference that can't do the needed calculation fast enough or yet another driver bug.

NGU and polaris release time is very similar and it was very fast known that polaris doesn't perform well if i'm not mistaken i was one of the first if not the first to notice and investigate on this.

not only was it hard to even get your hands on an polaris card when they where released the mining boom killed that product totally for the gaming market. if you now add the well known NGU problem it's not very great idea to get one if you want to use NGU.

fermi was decimate by GCN 1.0 for nnedi3 too this got better with kepler and was fixed with maxwell where AMD didn't even compete anymore and just refreshed old cards over and over.
and even then AMD was still faster and AMD had a bug where it lost about 50 % performance while decimating nvidia.
the 7850 and the r9 270 classics.

good old times. the fix not getting an nvidia card if you wanted nnedi3.

Does madVR have any API to display Overlay, like as Ctrl+J?
