FPS is significantly degraded in areas such as the Tangled Shore or upon entering the Clovis Bray Exoscience lobby on Europa. Some destinations have far better performance than others in the same instances of large amounts of action on screen or heavy lighting/effects. Reducing my settings in-game does very little to alleviate any of these drops. I was consistently striking an average of around 132fps before Beyond Light dropped on near max settings, but I can drop as low as 30 when first landing at the Tangled Shore now.
