Hey! No, it is not a problem with your PC. What you are seeing is quite normal, although people claim that the LOD distance used to be higher before the patch. In reality, as far as I know, before the patch, the LOD was identical to what you are now seeing from a distance. The patch added a higher LOD which only gets culled at a short distance. This aggressive LOD culling is indeed annoying, and should be fixed, but is not identical to the NPC pop-in I am describing. You can see that if you slowly back away from the house on the video, the wndows will "disappear" again (in reality, it gets "fogged"). In contrast, the NPCs I am talking about remain in place once they have spawned, and if you slowly go away from them, they will be visible from a distance from which previously you could not see them. In sum, we are talking about two related but distinct issues: The aggressive LOD culling introduced to lesser system load (probably) which is a feature (although I hope they change it) and NPC pop-ins, which is a bug, probably of the streaming algorhitm.
TL;DR: No, your system is fine, and we are talking about another issue, which is related
