Hi,

I am playing on a very big map with a friend that has a *very* big rail system and a lot of trains [>30] that are on paths >100k tiles long. As seen in the first screenshot everything usually runs smoothly. However, when I place or deconstruct rails anywhere, independent of whether connected to the big rail network or not, the performance decreases very badly while rails are being placed/deconstructed. I found this related topic on the forum but I think it's something different, because the trains already have their paths planned and don't need to recalculate anything.

Even though the game is modded I don't think the problem is caused by the mods since the mod uses game prototypes mainly as far as I know and doesn't actually use own code too much.

The mods should all be their newest version on the mod portal.

Thanks.

Thanks for the report however there's nothing I can do. You've built far beyond what the game logic can work with and you're experiencing the performance impact of having trains drive that far.

You could mitigate some of that by making the paths shorter: stops along the huge distances that the train check-points through.

Ok thank you in any case! Definitely gonna try putting extra checkpoint stops in between.
