Just to finish my thread-within-a-thread, today I updated my box from I7-8086K with DDR-2166 to I7-11700K with DDR-3200, both have/had decent mobos, memory also with as low CL as I could easily get, and I'm up from 9-10 FPS to 12-13FPS. I'd say that 20% increase here is significant :) (I haven't ...

TL;DR
Ghost trains should have ability to edit schedule

What ?
Ghost trains already can have schedule (when done by copying or blueprint). There should also be an option to edit ghost train shedule

Why ?
Currently there is even no way to see ghost train schedule, this would help here.
Also ...

I'm about to upgrade my box (CPU, mobo and memory) from DDR4-2133 to DDR4-3200 I should have a bit better latency, a bit more CPU L3 cache. If latency theory is true, I should see nice UPS improvement.


latency doesn't change as much with frequency as it does if you get high freq DIMMs with ...

I'm not sure if memory latency would show itself in %CPU ussage (on one hand, if CPU instruction execution is stalled by need to wair on memory, it should bee seen as %CPU usage, on the other hand, modern CPUs are so complex I can't be sure here.

I'm about to upgrade my box (CPU, mobo and memory ...

everything has to be checked on every tick, and you've got 9000 friggen trains, bro. that's absurd. you need to reduce the number of locomotives by increasing the size of cargo wagons. :?

This is my experiment with short trains. I like to check 'the other way' of doing things, and seeing many ...

I never claimed that my base is anywhere close to being optimal. I know it isn't, this is my first serious attempt to build a megabase.

What I claim is that it seems that my UPS is low while CPU seems to be underutilized. I do not claim all cores should be utilized fully, but I expect at least one ...

Sure, yes, depends on the map. But I'm not even close to using more than 32GB with my map. My total memory usage is about 28GB with map I posted and a lot of other stuff in the background (5 digital stores, LibreOffice, Discord, the usual).

32GB, so no not really.

I'm hitting possible performance bottleneck. My UPS is around 10, yet my CPU cores are under utilized, none of them even close to 100% usage. I know that Factorio is not very thready, but I'd expect at least one core close to 100%.

Trains should whistle a second before the're about to hit a player. So s/he can react.

Exactly, active pause. You can stop, examine what You did wrong, then unpase and fix it, instead of watching some disaster unfolding

Maybe not ver usefull, but amusing. Isn't it the goal of the game?

Mouse hover while game is paused should display the sam info about items when game is not paused.

When mouse hovers over a bot, it displays some basic information about it. But it is really basic.

I propose to extend this info to add some description of what bot is doing, example:

"Going to <icon> at <location> to pick up <icon> to build it at <location>"

I find current design of chests counter intuitive, confusing and not flexible enough. This is my proposal for change:

Instead 5 types of chests we have today, introduce one type of chests that can do everything they do, and more - a logistic chest :)

The basis for logistic chest is buffer chest ...

With big blueprints it is hard to remove things by hand. Zoom would help with that.

I have train running on schedule
I got it marked for deconstruction
I canacel (czrl-z) the deconstruction order before train gets deconstructed
Problem:
Train is on manual setting instead of automated.

This is my dump concerning trains and building track

With that base I got consistent 60FPS/UPS unless I'm building track. Base has a lot (3k+) trains and (500+ stops). On the bottom right there is construction of some structures set up, and while it is being constructed I see FPS/UPS drops down to ...

I did not want to overstep, I just theorized on what I've seen. I also did not take MP into account at all. Devs, thanks for your detailed explanation. Factorio is brilliant

TL;DR
Train path finding should not block the game, run in separate thread


What ?
Track building/removal and trains needs some love. I guess there is a train path finding cache, but building/removing track may slow game a lot. This could be optimized in the following ways:
1) track should have ...
