Thanks for the suggestions -
I've met this as well, if you turn on 'tb' in the console you'll see the actual grid lines and can see where your current ugrid radius extends out to. But yah I've noticed it isn't always a straight up 'x' radius around you and that thing with the grass going up into the hillside near whiterun is an example where it doesn't seem to just extend out evenly all the time. If you have tb on and then tfc to frecam and just zoom back into the sky you'll notice that the grid radius isn't centered on you in that spot but more centered around whiterun itself. Not sure why that is but yah you're not alone.
Thanks for the reassurance that it's not necessarily my incompetence or my system, likely an engine limitiation.
I tried tb and tfc, and the gridlines extend well beyond the area I'm getting grass popping in from.
I've been here a while, but not had a system that's allowed me to push things to see what they can really do! I was used to playing Oblivion at 15fps!
Did you increase uExterior Cell Buffer to a value appropriate to your uGrids value?
D'oh! I had indeed increased the uExterior buffer (to 100), but somehow had left the original line in as well (at 36) so presumably the latter took priority. I deleted the original. but still no difference unfortunately. I also went through both ini files to check I hadn't done the same thing elswhere or made any typos.
Here's my skyrim.ini in case it's any help in troubleshooting the issue:

I'm forcing AF through CCC, but letting Skyrim handle AA.
