Problem: Bug / Performance
I find an enormous number of vultures spawned on top of each other on the rock ledge near the little lagoon NW of the Sentinels (Coordinates -8863.192, 232536.547, -18613.434) They also seem to spawn in a line off the rock and drop to the ground as I walk into range.
The number of birds appears to increase the longer I am playing, to the point where FPS can drop in this area from 60 to 10 as i move through the area. I climbed the rock, killed the birds and got 1 fps for at least 45 seconds until it processed. Came back 20 minutes later, killed the overspawn of birds again, 1 fps again for minimum 1 minute.
edited to add no mods installed. Vanilla play.
