[BETA] Fast Track - Performance Mod for Oxygen Not Included

[EvilBoomer_ITA]

I'm having a new problem and I don't know what's causing it.

I'm playing a colony and it doesn't matter if I'm on cycle 30, cycle 90, or whatever. If I keep Fast Track enabled, the frame rate drops to 5fps. I see my 5070 from 1300MHz drop to 300MHz, and the CPU is at about 50%.

The triggering combination is something related to some conflict between the various mods I'm using, but before the January update, I had no problems! That is, if it was released in January!

Fast Track
Customize Buildings
Multiple Power Generator

When I search for High Voltage Wires, after a while the game starts to slow down, causing everything to stutter and the frame rate drops from 60fps to 5fps.

And a combination of MODs and Research.

It's as if that High Voltage Cable, which is modified in power by Customize Buildings, and the Battery Cable Generators by Multiple Power Generators, create a loop that Fast Track tries to optimize, but the queue gets bigger and bigger, creating this problem.

If I deactivate Fast Track, I have NO PROBLEMS after researching the High Voltage Cables, until I did that research, I had NO PROBLEMS.

And this whole configuration in the previous version of the game didn't give me any problems; I think I played it for 2 years without any problems.

EDIT: looks to be just a translation, so probably ok. Author has update the description to clarify.

Hi Peter, wanted to make you aware that a version of Fast Track has been uploaded to the Steam workshop: https://steamcommunity.com/sharedfiles/filedetails/?id=3726410223

While it appears at first glance to just be a translation the linked github seems to contain the Fast Track code. Did you authorize this?

Does anybody have a version of Fast Track from like mid 2025? that is the version of the game that I have, can't update because of horrible internet, can only access the internet from my library and have a flash drive, was wondering if anyone had this version of the game, I got all the DLC and that is the last version of the game that I have, the first one that has prehistoric planet pack stuff.

how are you playing it since its only available on steam and would not be available to play after nearly a year of being offline? 

I smell something with a black flag and a crossbones

Finally got around to start up ONI again after a hiatus and updated the fasttrack to 0.17.5 but the game crashes on launch and disables it.
Is fasttrack 'just' not updated or is there something fucky going on with my installation? -.-

Fast Track is not updated to the latest version.

This mod changes things in the game's code to achieve performance gains, so it's usually one of the last mods to update after major updates.

0.17.5 is from april 11th. You can lookup what version of ONI was live at that day. And THAT Version was the last one supported by faststrack. Every version after April 11 will not work with this mod. Its sad, but Peter has to adapt to every version all by himself, and he has a life too. So we all wait for it, and hope for a new version soon. But we all understand its nothing we can, nor want to enforce in any way.

Thank you! I thought as much but figured sometimes patches come that won't need mods to update.
But now I know and don't need to try to see if it's on my end and can just wait for an eventual update

Version 0.18.0 has been released. In addition to changes for the Aquatic Planet Pack (changes tested using saves not started with the DLC, but with the DLC installed on the client), path cache performance has been improved, and paths are re-evaluated much more quickly in areas with active digging or building operations.

You are a miracle worker!
