I have searched this forum multiple times and come up short. ACSS has issues on realistic mode as does all the other packs I've tried. I know steam edition has less players than mobile, and I know a fraction of the people that play steam edition play realistic mode, but as someone who does, I am dying for a complete solar system pack that works on realistic mode. I've been stuck with the default solar system for too long.
I like this one:
Complete Solar System , With Accurate Orbits
It has several very nice benefits. First of all orbits are realistic, not just circles. Also there is nice balance between quantity of objects and lags. Most other worlds have either much fewer celestial bodies, either much more and it lags a lot because of this.
This world however have the same bad atmospheric settings, as most other worlds - simply copied from default game world. Thus i had to manually edit atmospheric data in data files to make gameplay more enjoyable.
Also this world have simple textures. Those are beautiful enough, but not HD. You can replace textures with HD on your own, if it is important for you. There are plenty of textures packs.
And this world perfectly scales to realistic solar system at Realistic game difficulty, without any glitches. It gives all real sizes, distances and speeds.
