madVR - high quality video renderer (GPU assisted)

[huhn]

the difference is a VP9 profile 2 decoder.

3 GB will work for sure if NGU is not used. it should work with NGU and well you may need tweaking.

Whilst not strictly related to MadVR, one last thing to share for those with a Samsung SUHD set with MadVR - set your display to Games Console and set picture mode to Game for SDR and HDR material (Colour Space set to Native for SDR and Auto for HDR) - this disables virtually all image destroying features, leaving you to enjoy MadVR in all it's glory.

That rule pretty much applies to most TVs - in Game Mode or PC Mode, you basically get a "dumb" screen that just displays what its given.

Hmm, my present queue isn't filling up anymore, it stays at 0-2/15 and I'm dropping frames all over the place. I probably should have noticed this before but I haven't watched a lot of videos using MPC-HC in the past few days. I just went back to the previous GeForce drivers (391.35) so I think it must be the Windows 10 April 2018 update causing it. FSE freezes for me, too. Is this what others have been seeing? I don't have the game bar or any other overlays enabled.

Edit: Going to try the hotfix driver (397.55), saw some people reporting it fixes FSE mode.

Edit2: FSE mode seems to be working (and queues fill up in FSE mode), though there's a big delay so I'm wondering if I just didn't wait long enough before. Windowed mode is still busted. I noticed that FSE mode also switches my display mode back from 60Hz to 59.95Hz, annoyingly.

Edit3: Okay, I got it to use 60Hz by explicitly adding 2560x1440p60 to the list of modes it's allowed to switch to.

Yeah, that's what I thought, but with the Samsung SUHD's, PC mode activates crap that Games Console set at Game Mode deactivates.

[huhn]

only Pc modes stops downsampling on Samsung screens and it is often only available at 30 and 60 hz.

so GL with gaming mode and full glory madVR on Samsung screens.

if chroma subsampling is not image destroying feature than what is one?

I don't do gaming, so my rig is exclusively set as a HTPC, and 99.999% of all content I watch is 23.976.

Anyway, sorry for being off topic, was only sharing my findings that may help other Samsung SUHD owners who use MadVR.

What about the LG OLED TV's ? B6 , C6

for HDR you need to choose Game Console/HDMI instead PC Input , And choose HDR Standard Picture mode

what is GL ?

Yes. I and others have reported that 4k uses about 3.5 GB.

[huhn]

it is possible to make 3 GB work(i can even make 2GB work) but i stay at my Vram statement get a 4 Gb card for UHD.

Sorry I don't have an LG.

I have no idea what GL means.

[huhn]

GL=good luck

So which mode should I use ?

Windows HDR Enabled + Madvr 10bit + HDR Passthrough + TV GameConsole/HDMI Input + Full Windowed or FSE ?

Windows HDR Disable + " + " " + " " + Full Windowed or FSE ?


Because Windows HDR gives 8 bit + Dithering in Windowed and maybe FSE I think, and MadVR gives 8 bit when Full Windowed mode.

So which is the best choice ?

Would I notice any quality differences between 8bit Windows HDR and Madvr 8 bit Nvidia ? and also differences in MadvR 10 bit FSE ?

It is unknown what Windows does to the image, but the images should be identical between the two.

The best set up is to use the Nvidia private API (passthrough - send metadata), so you don't have to toggle HDR on and off. This is clearly most convenient.

To get 10-bit passthrough, you must enable fullscreen exclusive mode until there is a fix a the driver level for banding with 10-bit HDR passthrough when set to windowed mode. SDR playback is unaffected by this bug.

Edit - looks like Warner306 and I commented at the same time

Ok thanks . FSE is so annoying, takes ages until the images start to play when going in FSE. out is ok

[truexfan81]

evga 1050ti fw latest nvidia driver, windows 10 1803 madvr 0.92.10
any idea whats going on here?


thanks

Try small buffers, I like 6 for GPU buffers and 4 fames presented in advance. I have noticed that smaller buffers perform better than giant ones.

Also, it looks like you are not using the default flush and wait options? Put those back to the defaults.

Can you actually see any difference with 10 bit compared to 8 bit? I simply use 8 bit all the time, 10 bit is very unimportant for madVR's video out. Dithering FTW.

edit: I got it, had to add another profile for my image enhancements to turn them off for 50/60fps videos.

[Asmodian]

The reason this wasn't immediately obvious when looking at the OSD was because you turned off all the "wait" options in the "when and how shall the GPU be flushed:" section of windowed mode, "after the last render step" should be one of the wait options so madVR can report rendering times.
