The gamut would have to also be shared between the two formats unless your display has a setting to display each gamut accurately without a conversion. You could create two profiles: If (HDR) "BT.2020" else "BT.709"

Sorry, that's not quite what I meant and this might be a TV specific question. With this conversion, can I make my SDR mode perform like the HDR mode, minus the tone-mapping that would be done by MadVR now, if I calibrate it to max brightness and output in bt.2020? Or would using HDR mode still be the best option, especially on my TV? I ask because HDR mode is a bit finicky and I have a lot less control over the calibration.

It is a better option for a projector. Some still choose to use HDR -> SDR by sacrificing some brightness with HDR content for madVR's tone mapping. It partly depends on the brightness of your display in HDR mode.

i personally don't like bicubic 150 but that should be more than good enough. there is the possibility to scale chroma and luma differently which may not work with super xbr so NGU low maybe has the upper in this case.

yeah already doing that with argus monitor, useful little all in one fan controller tool, my GPU runs at 20% until it hits 60 degrees, it steadily climbs from there.
I've also logged a ticket with saffire to see if i have a fault with the fans or whether I can buy any quieter versions, its a current card so hoping I can. cheers, EDIT - got my figures way off, must have been thinking about another card. My current sapphire rx 580 nitro+ 4gb is only silent under 40% fan, if I run MADVR at NGU sharp high for both upscale and chroma it taxes my card about 70% GPU. I've found that if I set me fan curve to to run at 40% fan right up to 80 degrees it remains at a stable 75 degrees whilst running fairly silent, this was with a 4k HDR movie which seems to tax the card much more than upscaling from 480p to 4k for some reason... go figure...

In any case, this has NOTHING to do with the build you linked to, which is an experimental build for HDR conversion with pixel shader. I'm only saying, please post here about official builds, and there if you can help the work in progress instead of wasting our time. If you have any questions about upscaling 480p content, feel free to ask here but don't use an experimental build that had a bug to make a point. It's ridiculous.

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...

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.

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 ^.^ Last edited by ryrynz; 30th August 2018 at 01:37. |

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?

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?
