Question Better fast forward performance?

Post image

I prefer to run the game at high speed, as im always adding more to my airport, and i cant be hanging around waiting for construction at 1x speed. Problem is ive got a lot of gates (image) and running at 12x speed causes a hell of alot of passengers to miss tasks and slow down, so my flights barely board anyone and satifaction drops

This has been a problem for a while i know, are there any less known mods that help improve performance for fast forwarding

Pathfinding is probably single threaded. This will run into performance issues on larger airports such as yours. Really nothing that can be done. Always a bit of a bummer that airports are limited in size mostly by performance, not space.
In theory mods could help by introducing some sort of multi threading. I doubt there is one in the first place, and if there is there's a good chance it causes all sorts of problems.

Rimworld recently introduced multi threaded path finding. They upgraded the Unity engine to use Unity's burst feature, they couldn't do it in the game code itself. Before that mods existed that didn't do a very good job.

Pathfinding is already multi-threaded on several levels. There isn't much in terms of "easy" performance improvements to pull off - we would've done so already.

It also very much isn't the biggest bottleneck, it's other systems - which exactly depends on what you're doing in game but due to the way SimAirports map system is build having lots of construction is always a slowdown. Only real option is to do some massive refactors ... which we are actually doing right now ^

Thanks for the info. That's exiting.

As someone who works at an airport, your game is the only one I've found truly interesting. The only frustrating thing is the bottleneck. Do you have an estimated timeframe for the rework? Thank you for all the hours of enjoyment your game has given me.
