This vid doesn't look great on my monitor. Native Valheim HDR support in Win10 looks better than that on my monitor but I could believe the local dimming isn't fully utilized like the author suggested. I would like to see more contrast in tombs and crypts.

Valheim HDR is subtle. Red runes on a rock at dawn is most obvious. The atmosphere gradients or something feels smoother but they are pretty smooth already in SDR.
