Saw the last TEK and you mentioned optimizing Skyrim.
Could you please try uGridstoload=11 and uExteriorCellBuffer=144?
The default grids to load is 5 - that's why you see the grass and trees poping up when you walk around.
I've been dying to try this but couldn't 'cause my lowly FX-6300 can't handle the extra scripts that run when you jack up the uGrids settings.
So, what say you?
