yeah I enjoyed SI as well. it was a refreshing visual change from the main game
as far as mods, I usually use the following.
- Quarl's TP3
- UI mod
- BT mod
- All the downloadable mods from bethesda
- couple of other various graphics mods like better looking NPC's, lagoon water mod, better looking sky, etc...
I also bump up the ugridstoload value
to around 11 or so (haven't tried it with my new card yet) so that more distant objects get rendered. Big visual impact that makes things more realistic
