One thing that makes SH3 better to my eyes, is the 20Km atmosphere rendering such as in MEP V6.
It’s kind of killing me in SH5 or even worst in SH4. It’s a bit immersion killing IMHO.
When used to see it in SH3, it’s a pain to draw back the atmosphere in SH5/4.
But maybe FOTRSUltimate has it...don’t know, never tried it.
When observing boats far away, it’s night and day between those SH. Furthermore when up to 10 knots wind.
Maybe it’s hard coded in SH4/5, so no one made a 20Km atmosphere mod
