AMD, Intel and Nvidia driver issues and last recommended version

[Asmodian]

Sleep works fine for me too. Hmm...

[hotripper]

They acknowledge the bug but dont say how theyre able to recreate the issue. lol. Could be anything.

[hotripper]

Customers = Beta testers!!! Apply at Nvidia. com

[nevcairiel]

Why would they tell you how to reproduce an issue? They are happy if you don't encounter it.

In any case, there is a Hotfix driver thats supposed to fix it:

[hotripper]

It would be helpful knowing as to avoid reproducing the bug, in general, until a fix is released, which has been.

What does the CRD mean? 385.28 version seems unstable.The video images running on 385.28 version often go green while the playback.Furthermore,win10 18.09 and player often crash after changing screen refresh rate,for example,into 50hz(non-standard screen refresh rate)

[suanm]

The most point is that 385.28 version results in the wrong level of video images (images go grey)

[Asmodian]

Odd, 1809 does have a new WDM version and 430.39 is the first driver that supports it. Have you tried 430.39 or 430.53?

CRD means Creator Ready Driver, less optimized for games and more for creative applications. Supposedly, there is apparently little difference at the moment.

To fix the levels simply go into the change resolution section of the Nvidia control panel and set it to "Use Nvidia color settings" and set the output dynamic range to full.

Hello,master asmodian.
If i go into the nvidia control panel
and 'set it to "Use Nvidia color settings" and set the output dynamic range to full',Seems MadVR doesn't work anymore.All depends on nvidia control panle i set up.If so, that kind of the change actually gets meaningless.Because all i want is based on madvr.The major purpose is to play 4k uhd hdr movies with madvr.if madvr doesn't work anymore,all really gets meaningless.

[suanm]

i did a simple test for 430.39 version running on MadVR.Sure the levels of 430.39 running on MadVR was right while the plackback of 4k uhd hdr movies.Unfortunatedly my cpu burden rate was heavy,it was up to 100%.So i gave up 430.39 version.

[Asmodian]

430.53 is the hotfix driver for that issue.

This is not true. Setting those simply tells Nvidia what to do with the RGB data madVR gives it. Nvidia always does something with it and if you use the same setting as its defaults you get the same results.

Nothing madVR does controls how Nvidia's drivers set those settings, they simply default to some value for your display or you can manually set them. It is "use default" or "use as set", neither of those are "application controlled". If it defaults to limited for your display the drivers will compress whatever madVR sends. The drivers always assume the video they get (madVR's output) is full range, so if you set madVR to limited as well you get double range compression. With the drivers using limited range it is impossible to get madVR's full range output to the display as full range.

This applies to bit depth as well, whatever bitdepth is set is what is sent to the display, madVR cannot control what the driver does with the data it sends. If madVR sends 10 bit with the driver on 8 bit it will dither the 10 bit video to 8 bit before sending it to the display. If madVR is set to 8 bit but the driver is set to 12 bit it will convert madVR's output to 12 bit and send 12 bit to the display. If it defaults to use YCbCr 422 it will convert and mangle madVR's RGB output before sending it if you leave it on "Use default color settings".

I like setting those manually, that way you know what is happening to the video data. If you use full range RGB at the same bitdepth as madVR or higher nothing bad will happen to madVR's output.

@Asmodian
Thank you,master asmodian,for what you explain clearly.
I don't actually understand the relation between what MadVR does(MadVR outputs) and Nvidia control panel until you explain it above.So i will reset nvidia control panel to as you said or as you set.I will give up the default on nvidia control panel and set it to nvidia color control.Set desk color depth to 32bit,output color depth to 12 bpc,output color format to RGB,output dynamic range to full.If i do like that,whether I need to set MadVR to exclusive mode or not? Or i just need to set MadVR to windowed mode? if i set MadVR to windowed mode,nvidia will convert 8 bit color depth into 12 bit.If so,actual video effects or video images quality should be the same as you said above,doesn't it?

[Asmodian]

Yes, either windowed or exclusive are fine with those settings, no quality loss.

Klaus1189, you might want to add to the first page the link to the 430.59 hotfix posted by Nevcairiel that resolves the high CPU usage in 430.39 (especially until there is an official driver resolving this), and document it for 430.39.

Done.

Need offtopic info

so anyone found a fix for the stutter issues on rtx cards with the latest drivers? im stuck on old firmware because only way to avoid the stutters but missing out on this HDR update.

Download this

Also mentioned in first post. The second note in Nvidia section.

I'm using 430.53 with my LG C8, but I don't seem to get the 10-bit or 12-bit options in the control panel anymore. Was looking to play movies with the 23Hz option in RGB Full @ 12 bpc in HDR.

I'm only getting the 8 bpc option, any ideas? In the past I thought I had the 12 bpc option.

[Asmodian]

I have a 12 bit option for 23Hz RGB using 430.53 on my C7.
