Nvidia RTX Hdr issue

[Tecloudwoo]

Current Behavior

The Nvidia HDR RTX doesn't work properly with Wind Waker.
During 2 second it's correct.
After that, the colors are washed out.
Only for this game.
I don't know, Nvidia seems to find 2 HDR signals or something else

Expected Behavior

The other games as Zelda Twilight Princess, or Nintendoland display correctly Nvidia HDR. It's the normal behavior.

Steps to Reproduce

• Activate Nvidia RTX HDR
• Launch Cemu
• Launch Wind Waker HD

System Info (Optional)

OS: W11
GPU: 3080ti

Emulation Settings (Optional)

Set the preferred swapchain to DXGI in the nvidia control panel.

Same problem happens with Breath of the Wild.
Even after swapping the preferred swapchain to DXGI it does not solve it.
I noticed that the washed-out problem only happens with Vulkan. OpenGL works fine.

I have the same issue. Even with RTX hdr off, if I have HDR enabled on windows it provides an extremely washed out image when the game starts if vulkan is used, Opengl seems to be fine.

could this have to do with auto-hdr?

is auto hdr turned on or off for you guys?

-Select Start , then enter settings. Select Settings > System > Display.
-If you have multiple displays, select your HDR-capable display at the top.
-Turn on Use HDR, then select More options (>).
-Turn on/off Auto HDR.

Auto HDR is fully turned off at my end. Not sure if maybe autohdr changed something in the registry though? I HAVE used auto hdr with Cemu in the past.

I have Auto HDR turned off too on the Windows 11 settings.
By using OpenGL the problem does not happen, I can turn RTX HDR on fine, by using the Nvidia control panel setting below (this should work for Vulkan too):

With Vulkan I can see that for the first 2 seconds the image is ok and then becomes washed out.
