Totally understandable

TL;DR
Implement tailslayer for RAM reads (all? hottest?) to lower average read latency and address the most common megabase hardware limitation

What?
Avoid waiting for DRAM refresh with clever software tricks.

Why?
Bigger, more performant ...

You are right that this change does not eliminate all possibilities for collisions in self-intersecting paths, especially when a train path crosses itself at (e.g.) a right angle, since in that case there are no segments (which are delimited by intersections, signals, and stops) in common between ...

Could you explain why the cost adjustment I suggested won't work?


The one you suggested, a penalty at pathing time, only applies to the train's initial position and doesn't actually eliminate self intersection, even in all the examples you gave (the 270 degree turn). It also would result in ...

A minimal example of a self-deadlocking setup if the "never pass red signal" rule is applied, that is avoided with current logic. The train in this example is short enough that it will not self-collide, but the proposed pathing logic would deadlock it anyway.

The issue is completely removed when not using long range turrets... Thanks a lot. I really did not think something that small would cause so much lag.


My theory was that if turrets were scanning much larger than average areas for targets it'd add up pretty badly. How big of a range did you ...

Going entirely by vibes, my money would be on long range turrets or rampant.

Those don't look like normal laser turrets. No one can really answer your modded performance question without your mod list.

[*] This bug makes building large bases a fool's errand because the game will randomly cause my trains to crash despite correct signaling.


It's not random. Simply don't build loops shorter than your longest train.

Even without the collision failure mode, loops like this would cause a one-train ...

If it's flow rate limited and the generator arms and reactor cores are tileable then this could be scaled up to work with normal quality, yes?

Method 2 doesn't require any rewiring of the existing plant

I saw it called an "expansion" several times and that you can "upgrade" an account, and no indication it was an independent game. It also describes it as "continuing" the player's journey.

And regarding player limitations, the limitations of the game are meant to be in the mechanics, not in your PC hardware.

TL;DR - Limits via mechanics and complexity are fine. Limits via CPU shouldn't be.


Factorio has been memory bound for as long as I've been aware of the upper ends of ...

Just put a saddle on a Stomper!

Bots already wait to construct building in place sopmething that needs to be deconstructed.


Robots won't be assigned to build something until a robot is assigned to remove anything that needs to be deconstructed.


Could we change the suggestion to similar behavior? So the module bots will ...

"You want us to handle a weird edge case around insane levels of mining productivity? Eh sure, why not." Based Factorio devs as usual.

Ironically I'd say that power usage optimization really only becomes a thing with the Space Age expansion, because in vanilla you just build one big power net, fill all your assemblers with prod3's, and spam your choice of solar or nuclear to keep up with the demand. Full prod + speed beacons uses ...

(Also if you just want to play with delivering power by train, fluid wagons can transport steam.)

In general circuit connection will see all incoming signals from a circuit network even if they are being sent by the entity itself. So far the only exceptions are asteroid collector with set filters and assemblers with set recipe, but they were intentionally made to subtract their own output ...
