This is more of a general question, so I think general section is the proper place for this thread. I recently finished a playthrough with RotC 3-in-1, where I had most of the settlements evolve to lvl 3, with a few special locations (Sanctuary, Castle, and a few other) that I developed manually. While I never had any major issues (I was using maxed out performance options and complex city plans) on my system, I did have recurring minor issues such as occasional CTDs when travelling to/from settlements, cities not upgrading or not increasing built limits until I manually fix it, and so on. By the end of the game those issues started to be slightly more frequent, as I had every single settlement in the game being closed to maxed out. For my next playthrough I would like to do a settlement-free run, with neither minutemen nor raider quests. However, I would like to see most settlements as fully built lvl 3 cities, as it makes for a much more immersive experience, with traders and other options available for travelling mercenaries like the one I intend to play. Therefore, my question is as follows: if I wait for all cities to be fully upgraded to lvl 3 in the start up sequence, but then ignore/kill both Preston and Jammer, how much of script workload will there be for all lvl 3 cities? I assume that because they will be fully upgraded and I will not be capturing them, scripts that calculate needs, happines, production, attack/defense scores, etc. will not be running? So there should be less of an impact on my game performance compared to my last run where all settlements were captured, connected and slowly upgraded from lvl 0 to lvl3?
