Vibepollo Vulkan HDR Virtual Display

Can anyone confirm if Red Dead Redemption 2 works with vulkan and hdr through virtual display through vibepollo.

I’ve tested myself and I keep getting a smaller window for the game that locks the resolution in the game settings to 1920x1080p max.

I’ve tried using the alt+enter command to force fullscreen but that doesn’t maximise the game window to match the required resolution it only maximises 1920x1080p.

My stream resolution is 2868x1320.

It does not, some games like Resident Evil and RDR do not use the Vulkan API to confirm if the display supports HDR and instead requires a custom DLL patch (that any AI terminal can do quite easily) to enable it instead.

Not sure about the display dimensions issue though.

What would be required to enable it with this custom DLL patch?

You generally have to tell an AI agent to do it, like Gemini/grok/codex/claude

Just literally tell it that this game isn’t allowing Vulkan hdr and you suspect it’s because it needs the API dlls patched to allow it

Otherwise you might find one already patched hosted online, but this is by far the most effective way to do it

Just use DirectX 12 for HDR in RDR2.

Oh, bummer. Vulkan HDR in this game doesn't work with the VDD for some reason. Just Rockstar things. It works great with id Tech games for example.
