I just ran a settlement mission, and the settlement had drills, and my FPS dropped from 60FPS everywhere else in game to under 20 FPS. Elsewhere, though, it is fine.... getting between 50-60FPS in station concourses, for example. Running settings between Ultra and High (used Nvidia GeForce Experience optimized settings). GTX 1660 SuperI think some occlusion culling isn't working after update 5 at some places. You can check at ARAI'S MINE on IAH BULU, one of the best places to farm in Odyssey, it's a big extraction settlement, go there and just wander around, inside buildings eventually the frame drop will happen(while inside building try to look to the drills direction).
