ini tweak everyone should make
About this image
Sheson recently discovered a brand new LOD system implemented in Skyrim SE. It basically solves all the old game's ugrids issues. You can now set a parameter in your ini file that draws all medium and large objects at full detail for the specified distance, without drawing small objects and grasses that you wouldn't be able to see anyway, and without loading NPCs and scripts for all those extra cells. It means gorgeous draw distances at almost zero fps cost!
Skyrimprefs.ini
uLargeRefLODGridSize=11 <--- change this value to 21.
Quick image to compare 11 to 21 values. The distance extends well beyond the mountains though :)

both settings are important and especially ugridstoload change has an impact on performance, stability and gameplay (quest and event triggers).
your hardware (cpu, gpu, ram, vram) is also a limiting factor.
if you own capable rig you can try udridstoload=7 (in any case not more)and uLargeRefLODGridSize=21 or 25.
i play with 7 and 29 and 4k settings on a rtx4080. works without any instability and many mods.
make a backup and an extra save before you experiment with these settings. a save with ugrids=7 will not run with ugrids=5 settings!
Then press Ctrl+F and type ularge and press next. It will find it for u
