When i first entered the game i managed to get great frame rates maby around 150 fps. Then when i got over to the base i got around 110 which isn't bad at all. But here's the thing, the game started running worse and worse no matter what i did to a point where i got 30 fps only after about an hour. I think i found out why though, since whenever you run into an object in the game it gets physics and ragdolls around. But because of the way this game is made the physics of the object never really goes away. So basically whenever you touch something you load in the physics of that object, but those physics never unload no matter what. This is espasially bad in the base because that's the area with the most loose objects. The game only temporarily unloads something when your quite a bit away from it and also looking away from it. This is why the game runs 10 times better out in the forest especially when not looking at you base. So this makes it so that the more objects you run into the worse the game will run until it is entierly unplayable.
