[INFO] nVidia 436.02 breaks HDR in QZDoom

Forum rules
Contrary to popular belief, we are not all-knowing-all-seeing magical beings!

If you want help you're going to have to provide lots of info. Like what is your hardware, what is your operating system, what version of GZDoom/LZDoom/whatever you're using, what mods you're loading, how you're loading it, what you've already tried for fixing the problem, and anything else that is even remotely relevant to the problem.

We can't magically figure out what it is if you're going to be vague, and if we feel like you're just wasting our time with guessing games we will act like that's what you're really doing and won't help you.

Okay, since so many games are affected there's a good chance there will be another driver update in a few days that fixes it.

Just for info: only the vulkan backend has true HDR support and is controlled by the vk_hdr cvar. The OpenGL backend uses a different cvar (vid_hdr) and may be removed in the future as I cannot find any Microsoft documentation anymore for the feature it is based on.

I used both in testing.

This issue also applies to Heroes of Hammerwatch. Monster Hunter World is fine, but needs HDR to be enabled prior to going in game, as does Divinity Original Sin 2.

Are you using the OpenGL or Vulkan backend?

Just letting people know in case they have the same issue.

It was working fine the previous day, but after upgrading my drivers I find that previous and current GZDoom versions have the same issue, but nVidia has not broken HDR as such because I can view HDR videos via Microsoft Edge just fine.

Games require manual enabling of the HDR option for it to work, and others just wont display HDR, it just goes to SDR (Planetary Annihilation), but it otherwise works fine.

nVidia has broken something in regards to switching of HDR in this driver update.
