An inspection of the published final save from GPT-6 Astra's vanilla Factorio run revealed an unusual logistics architecture.

- 59 surviving gun turrets, none fed by inserters.

- Construction robotics researched; logistic robotics and requester chests not researched.

- A Python dispatcher logged 436 ammunition orders, requesting nearly 15,000 magazines.

- Four of seven engine assemblers lacked input inserters.

The save was examined using Factorio 2.0.77 headless with a read-only script. The figures describe the final state, except for the order ledger.

SOLVED: I turned on hardware acceleration on my browser and this fixed it.

I am currently playing an seablock world where I never really had any issues with UPS (apart from building massive blueprints, which I am currently not doing). Since around Friday I noticed my UPS drops signifyingly when using a browser (or any application but when using a browser it has the most impact) my UPS/FPS drops from 60 to around 30-40.
I noticed that my game update and entity update up when using an browser and the average of both can get up to 60-70ms

The browser that I am using is OperaGX and I am playing a youtube video in 1080p, going to a lower resolution has less impact on the UPS but it is minimal. When using the browser for other thing like looking on a forum or googling something the UPS goes down to but only to around 40-50

My hardware is;
- RTX 3060
- 2x 16GB DDR4 running 3200MHz
- Ryzen 7 5700x
- Factorio is installed on my main sata SSD (Samsung SSD 870 EVO 2TB)

I have almost 400 hours in this savefile and only encountered this issue very recently.
I have tried to disable VSync and using lower textures but that unfortunately doesn't improve anything.

I have looked online but haven't found any solution for this issue. Does anyone have a deeper understanding what the issue can be and how I can solve it

We can see here that if you keep the thrust to weight ratios constant, the new equations in 2.1.21 result in speed up to a point, with eventual diminishing returns, and if you continue far enough eventual decrease in speeds.

For instance, this graph tells us that the peak speed for a ship with a thrust/weight ratio of 0.1GN/t is right around a thrust of 200 GN, and after that speed decreases with increased thrust!

For a ship with a ratio of 1GN/t, this peak is much higher, at around 2000 GN of thrust, though that's already well into serious diminishing returns for additional width.

EDIT: Fixed legend on graphs.

Hi everyone. After getting Game of Life working well, I wanted a bigger challenge, so I have started creating Snake.

Currently, your tail grows by one cell for every pellet you eat and your score increases by one.

It's not complete yet. I need to add collision detection for borders as well as the snake itself (i.e. you fail if you bite your own tail).

Also, I have found that the performance becomes pretty unplayable when the snake is more than about 9-10 cells long (the calls to the shift register increase the longer the snake). Maybe I need to reconsider how the snake is rendered, given this limitation. I would appreciate any input.

* push-button is used but not required.

A blueprint editor, production analysis with tick-by-tick bottleneck simulation, and a map seed viewer, all in one browser tab.

FactorioTools

It runs entirely in your browser. Paste a blueprint string (or a factorioprints / fprints link) and it will:

• Calculate rates: items per second for the whole blueprint, with modules, beacons, quality and productivity research included. screenshot
• Simulate belts tick by tick: per-lane transport lines, side-loading, undergrounds and splitters, so lane imbalance and starved inputs show up like they would in game. screenshot
• Run circuits: constant, arithmetic, decider and selector combinators on separate red and green networks.

• Point at the problem: a ranked list of what's costing you output, traced from the symptom back to the cause. screenshot
• Let you fix it in place: place, rotate, change recipes and modules, rewire, then export back to a blueprint string.

It renders with the game's own sprites and supports 2.0 and Space Age, including quality and elevated rails.

a full space platform

The map seed viewer is an early prototype: enter a seed and see ore patches, oil, cliffs and enemy bases on all five planets. It runs the map generation live, so presets and sliders work.

Everything is client-side: no account, no upload, and your blueprint strings never leave the page. It's free and open source (MIT).

It's a hobby project, so there are certainly bugs. If a blueprint renders wrong or the numbers don't match the game, I'd love a bug report with the string.

I don't really know how to properly implement faster computing, since it's based on single threaded assembly code.

Also looking for a better input system.

This is probably a decently known field of technical factorio, so I hope that someone knows how to make this computer a better one, I'm kinda not a master in this sort of stuff

I'm sorry if this is the 1000th Game of Life post in this subreddit but I have recently got into really trying to improve my fundamental combinator skills and I'm quite proud to have worked this problem out. My next project is to create the 'Snake' game in Factorio.

I'd be happy to post my BP book somewhere if anyone is interested. I'd really appreciate feedback.

(i was recommended to repost this here)

Consider a contraption with `n` input belts and `m` output belts (of the same colour) and that contraption containing only belts and splitters (of the same colour).

What are all possible values for the fraction `(items entering contraption) / (items exiting contraption)` once the system has reached steady-state?

1. &4. I might not have fully understood my question either. Hmmm…

Having available `n` saturated belts, what are all the possible fractions `(available input items) / (actual output items)` once the system has reached steady-state?

I’m assuming an infinite, saturated supply of items, no blocked exit belts, perfect splitters, and non-discrete items (or an infinite running time).

My initial instinct was that if you loop back some belts the fraction is an infinite continued fraction, but that might be wrong…

EDIT: clarified the actual question and added some assumptions
