I'm having real problems with NPCs not loading, having to stand up to a min in a location I know they are before they show up.

Second but I think related issue is that some world-objects such as bridges and in some cases stairs are not "really" loaded and I just run right through them.
Also had alot of cases of falling through the world.

I don't have the best rig in the world, but it is over minimal requirements.

Anyone know if there's any reason this is happening? or are the minimal requirements just not really minimal requirements?
