: "HDR passthrough is broken with old drivers (including 398.11)"

I've updated my above post with a sample.

@Manni, can I ask what exactly "broken" means? Which metadata values are affected?

Also, what does OK mean? Are *all* the metadata values correct? (maxCLL, maxFall, mastering values, mastering color coordinates, white point?)
Broken usually means that HDR passthrough sends bogus metadata (usually the same for all titles). It can also mean that madVR doesn't manage to switch to HDR using the API, and that it stays in SDR. This is what happened to me with 398.11, and why I updated the driver to the latest. That solved the issue. I don't need HDR passthrough except for testing, and I need it more (and more often) than 3D, as I can use another source for that. No idea what broke it. Probably an OS update. In fact I wasn't able to install 385.28 or 398.11 without getting an error from the driver.

OK/correct means that *all* the metadata present on the disk is passed through, whether it's correct/complete, incomplete or invalid.

Correct.

696 with passthrough, 669 with 760 nit tone mapping. Not sure what you're expecting from this?

EDIT: Selected GotG2 when testing by mistake. Retesting now with GotG. One moment.

713 for passthrough, 669 with 760 nit tone mapping for GotG.

Very strange ... Thanks for the explanation!

Now I know (thanks to @SamuriHL's test) that 385.28 (on 1607) is fine as well, as you always told us so.

Can you do 1 more last test please, if you'll have time for it?
- use madvr pixel shader with the above posted GotG sample ("master luminance" 0.005/4000 ; maCLL/FALL 577/512)
- set 760 nits at real display peak
- What happens to the metadata values of: maxCLL, maxFall, mastering peak ?

Madshi said, they should be:
- mastering peak: 760
- maxCLL: 760 / 3 = 253
- maxFALL: ???

Thank You!

That's what I thought, but let's go over to the LG Oled thread.
Thanks for testing!

I don't see where they're changed in the OSD. I simply see:

master luminance: 0.005/4000
MaxCLL/FALL 577/512

So I doin't know if that's what you're looking for.
