This one shouldn't be too much trouble for those with the know-how, many of the ruins around Skyrim use LOD geometry so far removed from the full detail version that it's pretty damn jarring when they fade in, quite a large amount of locations around Whiterun have no LOD at all, it's possibly the one thing I had expected Bethesda to have perfected by now but I guess we had to pay for those mountains somehow.

To be honest I expect someone is already working on this but I thought I might as well throw my penny into the well
