Best Nvidia driver for madVR with hdr passtrough sending metadata to the display

<< < (2/3) > >>

furgiuele:
Thanks for the contributions.
I currently use an RTX 2060 card with 442.74 driver and switching from hdr to sdr works fine.
I don't use the pc for tone mapping because I have the Envy pro that does it downstream.
I have tried all the latest drivers with the 2060 and it always gets stuck in hdr.
I have now ordered two new cards to test if there are improvements, one 3060 V2 OC ed. and one 3050 but I would like to locate a driver with which the hdr jamming does not occur.
If anyone knows, I'd really appreciate a tip.

Yoo, how do you like the Envy? That's sick.

Also thanks for the tip about the driver version, I think on my dedicated renderer machine I'll try swapping to that driver. It only really does MadVR so I'm not hugely concerned about compatibility elsewhere.

Frankly, the 3060ti does all the 'rational' scaling / processing I realistically need. The 3090ti I use in my workstation can ramp up NGU to very high even when quadrupling. The differences are not huge (even viewed close up). One small benefit is that with rational scaling settings, the 3090ti chugs along pretty silently. The system is physically located elsewhere but if that's a concern for you, it might be worth thinking about.

Out of curiousity with the Envy, do you handle scaling on it or at the source PC?

furgiuele:
I upscale video resolution (->4k), chroma and luma with madVR on pc.
I use the Envy for all other sources, in the sense that it allows to obtain the improvement of madVR (upscaling, tone mapping, colorimetry calibration, etc.) without going through the pc.
When I use the PC as source, I share the video rendering between PC and Envy and the result is excellent (madVR upscales resolution, chroma and luma, Envy performs tone mapping and calibration).
Now I will try to replace the video card of the pc and I'm trying to identify a driver compatible with the hdr / sdr transition...

That makes a ton of sense :) Thanks for explaining how you do things.

I was messing around with my own cobbled together 'Envy' implementation for a while, I *think* I figured out the broad strokes of how they've set it all up. It's very cool to be honest.
Do you happen to know what capture card (or any identifying features on it) is used in the Envy system? Capture cards that *actually* do 7.1 audio are rarer than you'd think.

furgiuele:
HI.
I don't know what capture card is used in the Envy and I never opened it to avoid losing the warranty.
I can tell you that it works great, the lag is imperceptible.
I don't know how it goes with the audio signal because in my system it is installed after the preamplifier (Trinnov A16), so it only receives the video signal.
But I think it transfers the audio signal without modification or loss (bit perfect)...
Hopefully someone can point me to a Nvidia driver for the 3 series that goes well with the sdr/hdr transition...
