Larian Studios Forums Baldur's Gate III Baldur's Gate III - General Never ending noxious fume explosions

If I throw a burning torch into noxious fumes they start exploding seemingly endlessly. Pretty cool effect but very CPU/GPU taxing. Is that working as designed? Can't imagine what will happen if I lit the other fumes nearby.

I think it happens if there is a source that keeps on producing noxious fumes. Often there is a vent to discover. Sometimes the source is some kind of plant. Once you block the source (with crates, vases, baskets or other objects that are large enough) the fumes will stop spreading. Once a source is discoverd, it can be highlighted when you mouse over it. That can help moving or throwing an object on top of it.

Indeed, it's a trap so there is a vent there. OK, so working as intended, thanks.
