If you set the polling rate really fast you can get a better idea of the real load, something like 100 ms.

Depending on how the workload is structured, you would want an average load that takes into account bursts and idle periods. GPU-Z seems to not do that. Spiky 0/100 graphs are not very useful.
madVR is rather special in how it works load-wise, because it has practically no CPU limit, so when it can work it'll work 100%, but it has a hard frame rate limit, so it doesn't have endless work - ie. very spiky behavior. An ordinary 3D renderer would be CPU limited and/or capable of rendering an unlimited amount of frames, so it would either always cap the GPU, or be limited consistently by the CPU, but not simply by "time".

Just can't justify a Graphics Card more expensive than the TV I just got, so it is what it is. |

Also use DXVA11 native in LAV filters not copyback, it's way faster. Although the 3GB version of 1060 has less shaders than the 6GB one but I think it should handle 4k hdr well on 1080p screen. But you'll see I meant exactly this for a starter: Quote:

video card upgrade = dozen of presentation glitches every second
Hi,
I just upgraded from a Gigabyte Radeon HD 7870 to a XFX Radeon RX 580 GTS and now I get dozens of presentation glitches every second when playing any video if the HDMI Scaling slider is set above 0% in the AMD Radeon Settings GUI. I tried updating the Radeon drivers to 18.12.2 (was on 17.12.1 with the old card). but still get the issue. I've also tried restoring madVR's default settings. And I tried it with the same madVR settings I used with the previous card. I also tried the previous version of madVR. Never had this issue with the 7870 and I had the HDMI scaling slider set to 3% (which is where I also need it set for the new card). Thanks, >g. |

Peeps are just cranking the upscaling to arbitrarily high setting to saturate their cards. I'm not sure we can call that Performance.. at 2 meters from my tv, I can't even see the difference between bilinear chroma and nnedi.. I guess you could make a case for scaling 4K up to 8K tvs.. I have an old 7970, and it can do 4K jinc chroma, shader to SDR in 15ms..

My question is, How does changing the Sent meta data from rec2020 to dci-p3 change the image, if at all. How does changing the peak nit part of the meta data affect the image.. If, there is a change at all, what does the tv DO with that meta data, does it pop into different modes.

But, then again, it is madVR - after all. |

I am mostly playing UHD mkv rips and was wondering which madvr settings actually affect the picture since I am neither upscaling or downscaling.
Seems like only the settings under Devices, Processing and Rendering would make a difference, and Scaling Algorithms would not---but if I were to change NGU Anti-Alias to "High quality" it would obviously affect performance which begs the question: what are Scaling Algorithms doing to files that do not need to be scaled? |

Chroma still needs to be scaled. It's not about resolution. Chroma data is stored in 4:2:0 and needs to be scaled to 4:4:4 or 4:2:2 depending on what you're sending to your display. However, whether you can tell the difference between NGU High AA or bicubic75 or not is an individual thing and only you can decide with your eyes if you can see a difference.

I've got a 1060 6gb and I've got quite a few things enabled yes. I've had to change some of my settings recently because of new HDR tonemapping options that will be in the upcoming madvr release. It's a little more punishing than it is in the current release build. It's always a trade off of performance vs quality which is why you see so many people shelling out cash for 1080's and 2080's to make sure they have some breathing room. Everyone's configuration in madvr is going to be different based on what content they're viewing and what they're looking for in terms of quality.

the difference should be the image dynamic until it hits it max brightness then it does what ever it wants. as i said before there is no clear answer. Quote:
and as a fun fact 8 bit RGB has more BPP as 10 bit YCbCr 4:2:2. chroma is for most scenes not important up to a point that bilinear will be enough but as soon as an image get's chroma heavy or even based (red text on black background as an example) it shows significant differences especially on BDs where you are now literal using an good scaler on SD.
