Curious if the drivers expose any additional functionality over the 2xxx cards. I don't think we've yet seen anyone get their hands on a card so it'll be nice to see if the drivers are stable for them, what functionality hdmi 2.1 exposes in the driver if any, and the performance in madvr. Can't wait to see that kind of info.

I tried most drivers before that and had to revert all the way back to 442.74 to get predictable, reliable HDR<>SDR auto switch with NV API in madVR. Even 442.92 had some issues. Not sure why the more recent drivers stopped working, maybe an OS update? This is with 1909 and a GTX 1080ti (full config in sig). YMMV.

And what about this audio issue?

I don’t have these audio issues but I use HDMI bitstream as I need it for immersive sound. Bottom line is that here, with 1909 and a GTX 1080ti, only 442.74 or earlier works fully as expected (and I’ve only tested RGB 8bits). I use CRU so the better refresh rate of the new drivers doesn’t make a difference.

That's a bummer. Please let me know if I should update the Nvidia section.
If you have a spare SSD laying around, would be nice if you could set up Windows 10 2004 fresh on it and test the new driver. Would be interesting if the driver behaves the same on 2004. You can just put the old one back in the pc and the pc will work as nothing would had happend. I did this before on my own. I know it will be some time, but what what do we all for testing our stuff ;-) |

So I think I'm going to cancel next week and wait until we know more about the 3080ti as it might be on TSMC 7nm according to rumours, which might make it a bit less power hungry than the 3090. I don't really believe they'll move the already released card to 7nm, but that's still a slight possibility. This means that I might attempt to upgrade the OS anyway, but it's unlikely I'll find the time until early November due to work. I'll let you know as soon as I can test this. I image my drives before any big change, so I can always go back if there are more issues with 2004 and no improvement. For now, I would update the nVidia session and mark 442.74 as last known fully working driver re HDR for GTX and 1909 or previous, at least if your video chain detects content and automatically switches to the correct calibration (HD Fury Vertex/Diva/Maestro or new JVCs). Unless anyone confirms a more recent driver works, we can't rule out something in my config for course.

I'll check later this morning to see if they broke it again. They had fixed that in one of these recent driver versions. I'll need to find a working hdmi cable to hook the integral back up.

I don't think the issue is the same with more recent GPUs (or maybe a more recent OS).

EDIT: Found a working cable. Yes, on build 19042 of Windows 10 I am indeed getting proper metadata with 456.71. So there does appear to be a difference after all.

I noticed 1 issue (?) straight away, that I haven't before (not even with 442.92 SD): - 12bit nv output - madvr OSD is enabled - mpc-be/hc fullscreen window: madvr reports 10bit - but when seekbar comes up at the bottom: madvr reports only 8bit! I don't remember whether it worked like this or not previously. Quote:
The issue with HDMI audio is: - you have setup speaker config (e.g. to 5.1) and properties (e.g. to 41kHz) of NV HDMI device in Windows (under Sound in CP) - if you click on Configure again and cancel the dialog (or hit escape) then it reverts back to default (!) stereo 48kHz config This doesn't happen when you do the same with the Properties dialog.

I disagree, 12bit is the ultimate solution

I had to make an image of my SSD so I thought I'd give a quick try to 2004.
Bad news: the behaviour is the same with my 1080ti. 456.71 causes a fake HDR mode that prevents the SDR calibration to be selected. 456.71 was installed after the update, so I tried a full clean install with CRU, same results. I had to revert to 442.74 to get the expected behaviour. So the OS has nothing to do with this. The good news (for me) is that the OS update finally resolved my super long start for the nVidia cPanel. I'm back to normal start time of a few secs. So unless I find some unseen downsides, it looks like I'm going to stay on 2004. I'll update the thread if it wasn't the case. Again, this is only for GTX as I haven't tested the new drivers with GTX. I have also only tested RGB 8bits

That's seriously crazy that you have such wildly different HDR results on the 1080ti than I do on my RTX. What the hell is nVidia doing lately.....sigh
