Hi Madshi,
thank you for your great program, it really improves the video quality on my 1080p display compared to other pc video players, or when using a stand alone bluray player (assuming the source video file is of good quality) Q1) is there a way i can set my display max nits in madvr ? i am using madvr on my win 8.1 pc to play some 4k hevc h265 rec2020 video files, which i output over hdmi to my 1080 display (which is accepting 1080p 12 bit 4.4.4 RGB full) . in madvr settings i am using DXVA2 for down-scaling wich gives me a gpu load of 72% and uses 90% of my 3gb vram (the other custom pixel shader settings like SSIM cause a significant rate of frames being dropped and i get micro stutters) some of the 4k video files are HDR (which i know is not part of the SDR specs), but my 1080 tv display has a spec of 380 nits (compared to most older 1080 displays only going up to 150 nits usually) i know that some of the higher end stand alone 4k bluray players (like the samsung or panasonic) allow you to select a max nits setting when outputting the 4k HDR video to 1080 (for ex on the samsung player i would have been able to set it to 350 or 400 nits iirc) can i similarly set a max nits setting in madvr for my 1080p downconversion output ? (i remember discussion about this taking place in the madvr forum, but cant find the settings) note: i am aware most HDR movies can range from 500 to 1000 nits (or even higher w dolby vision ?), but my display relatively low 350 nits ability would be nice to be able to use for higher luminance detail available from some of these HDR source files Q2) is there a simple way i can save my preferred presets for different resolution video files that i might be playing ? (eg 720p, 1080p, 2160 4k files etc) - for my pc hardware i can use higher quality settings for 720p and 1080p files, but for 4k files i can only just play them and have to dial several settings down Q3) when playing 4k files (with my limited settings ) my GPU reports 72 or 75% GPU load, and 93 % vram used for ex, but my i7 cpu is only at 20 or 25% load. - is there a way i can offload some of the video tasks more to the CPU and then be able to enhance other settings in madvr that are GPU load dependent ? i have tried different "video decoder" selections in mpc-hc, but it doesnt seem to alter this (am using dxva2-copyback as this was suggested by you in an earlier setup guide iirc) pc specs: win 8.1 (64 bit) w most recent video drivers and updates, i7 4770k, 32 gb ram, 1060 3gb GPU using mpc-hc 6.3 with madvr latest version |

One more thing and I am unsure if there is an issue with madVR and my TV. The one easy thing I seem to have is NV HDR is ativated quite easily, which is a blessing on having read back over multiple threads on it not for some people due to drivers et al. But if I select the OSD for the TV once activated, sometimes it says BT 2020 and SMTPE 2084, but mostly only if I change a setting in the settings side of the TV. The majority of the time it will say RGB for colour space and 2160p24, but sometimes it will say 2160p24SMTPE 2084 for video and BT.2020 for colour space. it looks to be getting the right information from looking at the madVR OSD, so is this an issue with my TV not being very clever and I can just ignore it, or do I need to mess with drivers to get this correct information. |

Have a look at this guide for the presets, under profiles. Also the target peak nits under HDR, but would assume you have seen this ? Last edited by madjock; 7th January 2019 at 16:49. |

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 ![]() ![]() 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. |
