Odd problem (LOD, I think)

[Oraiu]

I've been noticing a rather strange problem wherein Skyrim seems to load the long-distance LOD textures when I'm close to things. It even fails to load the collision models of buildings and trees. I've attempted to reinstall Skyrim, and it seemed to only fix it temporarily.

System information and such:

I have Skyrim on Steam and launch it through skse_loader.exe. I have Script Dragon installed for iHud.

 

Preemptive thanks for any help!
