Problem with Vulkan's HDR

Postby p0n1at0wsk1 » Mon Nov 23, 2020 8:37 am

So, I've updated GZDoom to the latest version (4.5.0), and that's now what I see when HDR is on (for example, in Heretic):


And that's how the game looks like when I turn HDR off:


For comparison, this is how it looks in GZDoom 4.4.2 with HDR turned on (on my display it makes the image a bit darker version of the image above):


And without HDR it looks basically the same as in 4.5.0.

So, the question is: is that how HDR supposed to look like? It makes the game too dark and faded(?) on output compared to the previous GZDoom version, where I could just increase the brightness setting with some contrast above and the image will be more or less visible on my display (unlike the latest version, where neither brightness, nor gamma correction will help).
FYI, I have the latest version of Windows 10 (20H2, build 19042.630), GTX 1050 Ti with the latest driver version (457.30 to be exact), a display with HDR10 support and 2560x1080 resolution (native 21:9).

EDIT: Oof, seems that I wrote a slightly wrong driver version. Also, I wanna say that I made these screenshots with default brightness, gamma and contrast settings.

This bug may have been introduced by the srgb to linear fix I got Rachael to apply. Undoing that commit will probably fix it.

I can't really test anything HDR related anymore as I sold my HDR monitors.
