How many settlers should I use on the XBOX?

Hello all, I am concerned about crashing due to a history of the XBOX one slowing down or crashing when playing fallout 4 with mods, so I thought I would ask how many settlers are suggested for settlements to avoid issues?

Generally at the very most, roughly 20, however, problems can begin to occur even before then. I myself have managed to get about 20 in Castle without much trouble and had around 25 at Spectacle Island, however, the latter was quite problematic with crashing the game.

So I assume that 15 is going to be OK, as that would be 30 buildings if I am using SS?

It should be relatively safe, but as I said, it can sometimes be finicky even with only that amount of people. There's more that goes into the performance than just the number of plots. You have to think about other mods you have installed such as certain scrap mods, texture mods and even SS add-ons. It's completely possible to only have one plot and still have crashing (Very highly unlikely however) if the plot has an insane polycount. In my limited experience, most plots are around 50K Polygons, which is what the game must render, the higher the polygons, the harder it is for the game/system/engine to handle the load and thus resulting in crashing.
