Next Gen HDR - best tool

Hello everyone,

I’m playing the next gen version (dx12) on PC and want to use HDR. I’ve read somewhere that the native HDR is only a brighter SDR version.

Has anyone experience with it? Should I use the „native“ HDR and leave it be? Is RTX HDR or auto HDR better? I saw that there is a new RenoDX HDR mod on nexus https://www.nexusmods.com/witcher3/mods/10900

Thanks in advance!
