AMD, Intel and Nvidia driver issues and last recommended version

[Klaus1189]

It depends on your model and what you need, for example do you need 3D support? RTX or GTX model?

[xabregas]

GTX 1660 SUPER, no 3d support but i have 4k HDR screen even knowing i dont play a lot of HDR videos. But usually just watching bluray 1080p videos upscaled to 4k and im very confused about this studio vs gaming driver. What is the best for madvr? studio or gaming? I know my gpu is very new and only the last 2 drivers work.

[Klaus1189]

Use the latest GRD or SD, it shouldn't matter, as long as the version number is the same. GRD is updated more often, SD rarely.

[SamuriHL]

The latest nVidia drivers, knock on wood, have been pretty stable lately when it comes to video playback. No major issues with them on my RTX cards thankfully!

I signed up at vanguard beta program, but didn't received an email

[mclingo]

i didnt either mate, guess thats a no then

i think they've changed something in 20.2.2 AMD, colours look right but image doesnt have the right brightness, can somsone else install to see if you are seeing what i'm seeing.

[mclingo]

this might look fixed for people with low nit displays or projectors but the picture is very dim compared to Windows HDR turn on, this suggests its with still not outputting Bt2020 or its somehow sending the wrong meta data or something, this is really odd.

[SamuriHL]

Maybe someone with an hd fury can check what's being output for you.

huhn is running a navi card but not sure what display, might be hard to see what i'm seeing without a bright display, ideally someone with a NAVI card and an OLED.

It's busted, so don't bother - switch to Win HDR, press play...all fine...fast forward/skip, and it seems to flip to limited range (at least on my rig).


Back to the last lest busted version.......

Do they hire monkeys?

EDIT - and no, the AMD API still does not switch to BT2020, outputs 709....but they also manged to break the Win HDR toggle when you fast forward/skip, as explained above.

How can I check that?

[mclingo]

I think you may have some issues with your rig mate, i'm seeing no issues at all apart from the image being a little bit dimmer than windows HDR. Toggle is rock solid here, tested KODI DS and MPC-HC, skips also fine in both.

if you have FSE turn off your movie might just be popping in and out of HDR mode if you move your mouse, put FSE on and try again, i see what you are seeing in MPC-HC with FSE turned off when i move my mouse, this is normal.

[mclingo]

lets see what DMU and Huhn report back, sure this is BT2020 now, just too dim.

I ask because the colors do look right to me, but that doesn't mean there could be still something wrong. I also think it is a bit dim too, but usable nevertheless. Fast forward does not produce any problem here.
Did you wipe the old driver? I used the AMD Cleanup Utility, linked in the first post.

But it looks like things are getting better now ;-)

[oldpainlesskodi]

Ok, I'll try again to rule out FSE. But my display was still reporting 709 with the AMD toggle, and 2020 with the Win HDR toggle, but i'll double check and report back.

[oldpainlesskodi]

Yep, rolling back to 20.1.4 - have double checked the variables I can think of, so, at the moment, my original post on this driver stands as is on my set up.....if it's working for you guys, would be good to understand the difference.

[mclingo]

you should not roll back just jet, you need to find out whats going on. its not really clear whats happening for you, is this all happening in KODI DS?, is windowed mode on or off in KODI, how are you determining what output is being sent to your TV?

[oldpainlesskodi]

1 - Kodi yes.
2 - Windowed in Kodi - no, always keep fullscreen, but tried FSE and windowed in Madvr.
3 - TV reports 709 in the latest AMD driver with HDR playback, and using the WinHDR toggle, like I said, it reports bt2020, and looks fine until in Kodi you press next chapter, and then it lose's all of the dark/lower detail, like its gone to limited range. No such issue with this on 20.1.4 - I have triple checked.

Like you said, lets see what others find.

[mclingo]

hi, your TV actually reports what colour space its receiving? and if you turn on windows HDR it reports bt2020 and with it off bt709?
