Blender 5.0 Introducing HDR Support On Linux With Vulkan + Wayland (phoronix.com) 11
Michael Larabel writes via Phoronix: The upcoming Blender 5.0 3D modeling software application is introducing High Dynamic Range (HDR) display support on Linux when making use of Wayland -- no X11 support for HDR -- and Vulkan graphics accelerator. HDR support for Blender 5.0 on Linux is currently considered experimental. Enabling the HDR support on Linux for the Blender creator software requires having a High Dynamic Range display (of course) and be running on a Wayland desktop, enabling Vulkan API acceleration rather than OpenGL, and enabling the feature currently deemed experimental. Additional details can be found via this Blender DevTalk thread.

I hear more than 8bpp works kind of ok with AMD on X, but it definitely doesn't work well with Nvidia... Which also doesn't work well with Wayland. Looks like users who want HDR can choose between AMD or Intel, and Intel is going away.

I believe we've been over this before. It appears I failed at making you understand.
You cannot explain to me what you do not understand.
>8bpp is not HDR.
If they weren't talking about higher bit depth, it wouldn't matter which display system was involved. The most popular format for HDR displays to support is HDR10 [wikipedia.org], which involves 10bpp. You can view HDR content on 8bpp displays, but you won't get full fidelity. Remember Half Life 2: Lost Coast? (Apparently Riven also used HDR techniques, can't say I noticed.)

X does not support HDR, period, end of discussion.
I can make HDR images on my camera using Magic Lantern, and have done. It uses the technique where they're generated from bracketed exposures. They are striking even on a normal display with a typical color gamut.
Same name, different thing. I can see how that would be confusing for some people.
Even displays with 8bpp panels can get more out of having a HDR signal (including >8bpp) so even I would like to have it, with my cheapass LG43UT80[00].) Unfortunately, I have an Nvidia card.
Repeat after me. HDR is not >8bpp.
They are entirely separate things.
You can have an HDR transfer function and color space with 1bpp if you like (though less than 10 is painful)

10bpc has worked on X for NV for literally decades, now.
However, that is not HDR.

Nowhere did I say that X did HDR.
What I said about this being the domain of AMD is that Nvidia drivers for Wayland don't work well. And this is becoming a problem for Nvidia more and more in general, which is ironic because I've always used them specifically because AMD was bad at drivers. Last I looked they still were on Windows, maybe that's better now, but I don't care about that at all.
The other thing I said was that 10 bpp is a requirement for output in the most commonly used HDR Display output format,

This is similar to what is called "HDR" in images (which are also not HDR, and very much not 10bpc (though they can be that- or even more!)
HDR support in Windows did not exist until Windows 10.
The other thing I said was that 10 bpp is a requirement for output in the most commonly used HDR Display output format, which is still true.
No, that is confusing TVs with computer displays. The "HDR10" standard does require 10bpc, but that is not "HDR". That is "HDR10, The Standard" (A collection of technologies someone may want in order to sl

HL Lost Coast does not use HDR
It renders in HDR, then it does cute tricks to represent the HDR content on a normal display. This still improves the visuals in both bright and dark areas, accomplishing a huge percentage of what you expect from HDR.

The scare quotes ship has sailed, that's always going to be called HDR.
HDR support in Wayland is accomplished by allowing the clients to set color space and giving them floating point pixel buffers. NV does all of this just fine.
It does, what it doesn't do is work reliably.
The NV drivers are still fully featured.
IME they've been problematic when I've tried Wayland. I've been sticking with X11 as a result. It's then disappointing that 30 bpp does not work well with Nvidia with X, but sadly

No, it does not.
It simulates what an HDR image would look like for you with things like blooming, slowly adjusting the contrast to simulate your eyes adjusting, etc.
There is nothing HDR about its rendering.
It's a very cool effect, but it results in a loss of detail, not an increase.

Sure, I agree with that. However, it's entirely distinct from what is called HDR on displays.

Depends how we define reliably.
As mentioned, AMD recently had a color space application fuckup for HDR as well. Do we consider the A
