Fascinating...
So about that Technical support I asked for? Here's some details that might help:
Northern shores of Solitude: Draw distance drastically increased. Castle Volkahir looks much sharper in the distance now, tree LODs along the shore are a substantial improvement.
Around Fort Amol, standing on the Whiterun side of the bridge, trees on the other side of the Fort are LODs. It takes less than ten seconds to reach those trees, that's how close we're talking. Those should not be lods, those assets should be loaded in, which is what was happening before and isn't happening anywhere else I've been since installing (I haven't been all over Skyrim yet though). See screenshot.
Northern Whiterun plains: From the northern side of the northern bridge on the crossroads of bridges (next to Honningbrew Meadery), start walking towards Loreius Farm, by the time you get to the Northern tip of Whiterun, parallel to Dragonsreach, terrain begins pops into life (the transition point between grass and snow). It was doing this before, this was the reason I installed DynDoLOD, I wanted to eliminate that.
Enhanced Landscapes mod, Barren Marsh option. The entire marsh is covered in LODs. No assets, which is as it should be, just ugly, flat, 2D, low res monstrosities that look like they're straight out of Daggerfall.
There's four simple examples of the inconsistencies I'm getting. I asked about draw distance because Castle Volkahir looks significantly shaper than it did, and on the approach up the mountain, on the road to Riften, I'm seeing Mountains in the distance in the direction of the Hot Springs, mountains that I've never noticed before and don't appear to be the kind you can travel to and climb. I don't know whether this is a result of my ENB or this mod, so I'm trying to determine precisely what this mod changes. Is it just tree lods or more?
