(NDU registry change) Increase performance immediately! AMAZING!

Despite the clear breakdown of this fantastic guide here [HOW-TO] Graphics Settings and Performance Guide (SU5 Complete Retest) (8/2/2021), I still worry that if i change many settings from high to medium, i would lose some details/immersion while flying VFR.

Water waves i have on medium.
Cockpit refresh rate i have on low.
Buildings i have on medium.

And that’s it. Pretty much everything else i have set on high.

(Grass and trees i always keep at high because i do notice some density loss when setting them to medium.)

So can anyone put my mind to ease and tell me that IT’S OKAY to change some other settings to medium as well without losing much immersion in VFR?
