My 1080 GTX can do NGU doubling to 4k res in combination with edge sharpening, detail enhancement and error diffusion dithering in around 28 ms. That's enough for every 23 or 24 fps movie and even for 29 fps videos.


What is not working for me is the custom resolution functionality on Windows 10 1803.
Yeh, my 980ti can just about manage NGU High, it sounds like a aircraft though after a few mins though....

noise is the biggest problem for me now with MADVR, its so bad on my RX 580 i've had to move back down to NGU Low from HIGH, have been getting high with sub 20ms rendering which is pretty good for polaris.

Thought about watercooling my card but to expensive and too much of a faff.

I've done as much soundproofing as I can, you can only go so far before you ambient temps get too high, my PC is now idling about 45 degrees which isnt great.

My previous card, RX 460 used to be very loud and could barely manage NGU LOW though so upgrading to the RX 580 was still a good buy for me as I can get NGU LOW on 40% GPU fan which is pretty much silent.

you should check benchmark to see how a card is performing in term of temps and noise.

i can't remember a card i brought that was even remotely loud.
if it was the r9 270, 760, rx 480 or my 1060 "all" where properly cooled and never good loud at all temp and not problems too.

and i don't even use a case fan...

there is no way other none reverence cooled mid range cards are that bad. try a custom fan curve and don't forget 80 degree is save for a modern GPU. or even lower the power target, under volt and/or under clock the cards.

Regarding chroma upscaling is this true? I saw it in a guide:
"The sharpness of the algorithm used in chroma upscaling section should not exceed the sharpness of the algorithm used in the image upscaling section. It could be the same, but not exceed it."

Its basically pointless to use a sharper chroma scaler then Luma. If you have processing power to spare, use a better Luma scaler instead.

Thank you for the info. In my case I can't use anything higher than Jinc for luma upscaling.

while i totally agree that you should not use processing intensive scaler on chroma if you have to scale luma. but i disagree on the sharpness.

i personally use super XBR 125-150 on chroma and super XBR 100 on image scaling.

I guess you use image doubling, right? I'm on 2560x1080p monitor watching 1080p movies, and I see no point in using image doubling, image upscaling imho is enough.

even on a 1440p screen doubling can be cheaper.

ngu AA low and super xbr maybe cheaper and may give you better results.

but yes i'm doubling and without doubling i personally pref super xbr 100 for chroma.

That may be true, but after the doubling is done, it has to downscale it.

yes it have to be but even then it doesn't mean it is more expensive.
2x scaler are so good in madVR that is may be worth it and downscaling has a very very high level in madVR.

I'll do some testing with the doubling, is SSIM 1D 100%+ scale in linear light and AR-relaxed a good downscaler?

Madshi says GTX 1050 = underpowered with latest Madvr setting, which means RTX 2080Ti is a must, haha

s.
my card nearly hits nearly 50 decibels at full load which is apparently normal for this card, i've never hard a card thats quiet at full load though, pushing that much air has to make a decent amount of noise.

Mine is silent up to about 60% fan

Come on, it's a non-optimized test build with a bug (no x64 support), don't be ridiculous! It's been fixed in build 10, two posts down (https://www.avsforum.com/forum/24-di...l#post56716852). Please don't comment here about the experimental work being undergone there. Anyone installing these test builds should understand that they are a work in progress. Post there if you can contribute, otherwise wait for the next official build and discuss it here.

Is the HDR -> SDR tone-mapping work done in the other thread beneficial for use on an LG B7 in HDR mode (bt. 2020, ~750 nit max, etc.)? Or is it only useful for converting to rec 709 and ~120 nit?

actually currently no video card could run the highest setting of madvr-upscaling, like upscaling a 480p video to 4k, even the 1080ti drops a lot frames, my friend tests it with a common anime video (x264, 500MB, 20mins)

You can set madVR to tone map and then pass the result to the display in PQ with HDR metadata. But you would have to find a target nits that disables the display's own tone mapping. And, even then, the display might still alter the input in unwanted ways. You would have to experiment with this setting in the hdr menu (process by pixel shader math).

HDR -> SDR can output to any brightness or color gamut. The problem is your SDR calibration would have to balance both formats. SDR is most accurate close to 100 nits, while HDR is most accurate close to 1,000 or 4,000 nits. So it isn't easy to balance the two with a reasonably bright display.

A noisy fan is common with a budget card. I made this mistake once and wouldn't make it again. I can't believe how bad the fans are on some GPUs. The gaming models can be nearly silent under load.

Try installing MSI Afterburner and creating a custom fan curve. You can keep the fan at idle or at a low speed until the GPU becomes very hot. If the card never gets past this temperature with your desired settings, then you don't have to worry about excessive cooling, which the default fan profile will usually do.
