https://pasteboard.co/IaK4q6j.pngThe above comment, is that for my version? 43' doesn't have Full UHD Color I don't think.

Edit: looking at the picture, and I've noticed it with another movie too, is that it flips in the middle of prensentation. Goes from correct coloring and so on to washed out looking like in the picture.

you are upscaling 2160 to 2679 why?

To simplify things, set the GPU to 8-bits at 60 Hz and don't worry about 12-bits. It won't lower image quality or create banding.

Given the peak brightness of your display, I would convert HDR to SDR with pixel shaders. Set madVR to BT.709 and either 2.20 or 2.40, whichever gives you the better HDR picture. The gamma setting won't impact SDR content.

edit: it's me doing pan & scan - scale to 16x9

now if someone could help me with the gpu spike. It went from like 61% to 97/98% after upgrading to the 4k tv. is that normal?

Did you move from hd to 4k?
If you were running 4k previously did anything else change? Bit depth, frame rate, hdr etc.

I went from a 1080 tv to a 4k tv. The only thing that changed was the nvidia control panel. It started with RGB/Full/30Hz when I first plugged it in. Then I switched it to 60Hz. It will only do ycbcr 4.2.2 Limited at 60Hz. I can't choose anything else at 60Hz. Nothing else changed. I have tried Clear Action on/off, film mode on/off game low latency on/off. I have changed chroma upscaling/checked everything in trade quality for performance and so on. Nothing is really getting the gpu spike down. Also, I did find Full UHD Colors under a different section. It's on now.

ok, screwing around with it some more shows me that if I run mpc-hc with controls still up, not going into full screen, gpu usage is at about 76%, full screen gives me 97/98%. I swear this can't be right for a 1660ti. Everybody said these would be good because of the extra vram, but this has all given me kind of a headache so far.

then don't do that and it should be fine.

It sounds like you need to change your settings, madVR can bring pretty much any card to 98% usage when upscaling 4K. Both the number of input pixels and number of output pixels matter when scaling so doing 2160 -> 2679 is going to be very hard. Downscaling or especially not scaling at all is much faster. If you are watching 4K going from downscaling to upscaling, when switching to full screen, is going require very different settings.

Are you playing UHD movies? These use the HEVC/H.265 codec to highly compress the video, which puts a huge strain on the CPU if you're using software decoding.

The 1660ti has a dedicated video processing chip for encoding/decoding HEVC. Go into your LAV Video settings and choose hardware decoding. From the dropdown list, choose "NVENC". Once you do that, your CPU usage should drop way down.

As far as GPU usage goes, you shouldn't need to do any scaling for 4K UHD movies. With no scaling to do, madVR will not tax your GPU to the degree you're seeing. If you're upscaling 1080p movies with NGU, make sure you're ONLY doubling (not quadrupling then downscaling) and play around with the strength settings. Your GPU should do at least NGU High for luma upscaling with no problem.

well, taking scale to 16x9 drops down gpu from 98% to 76%, but the video still stutters and I really want to be able to watch these movies in full screen.

Also, the CPU barely has any load on it, it's all on the gpu side.

Then I think you must be doing unnecessary scaling, either up or down or both. My GTX 1080 doubles 1080p to 4K fullscreen with much lower usage than you're getting--50% on average. I don't have any UHD movies, so I can't give you a comparison there.

I just tested with dsplayer and it has dropped gpu usage massively. I'm only getting 40% tops using it instead of mpc-hc

Edit: I also wanted to add that I haven't completely set up dsplayer again. I just tried to run it with fresh install and it dropped cpu usage by almost half. Will still have to see as I continue to set it up proper.

Edit Edit: it's definitely madVR. As soon as I switched to madvr profile it went right back to 97%

Post the settings you are using, either in screenshots or in a list. It's either the driver for the 1660 Ti or something you have checked in the control panel.

Are you at least outputting to the correct resolution?

it's the beta build of madvr doing it. I went from last public build, giving me 59% to last beta build giving me 97/98% I'm just going to start fresh with madVR. Since it's a new tv, just going to try and setup everything fresh and take it step by step.

That'll likely be the new tone-mapping settings which you don't require.

now I have a problem of video stuttering when trying to pass through metadata with passthrough.

Well if everything's fine with it just use the last public build...

Do I still get calibrated picture with hdr to sdr 3dlut or it's just for tone mapping?
