The extreme brightness of island, deck and IFLOLS ligths is still an issue on v2.9.20.15384. This screengrab was taken on Sept 28th 2025.
It ends up being possible to distinguish light sources (and seeing the deck) when getting very very close, although it's almost too late for most visual corrections at that point. I tried disabling DLAA/DLSS and light bloom effects and it didn't change anything (restarted DCS each time I changed a setting to make sure it took effect).
I'm in VR on a Pimax Crystal.
