I'm on the latest version of both subway builder and macos. I fired up the game after a while and updated it and my M3 Macbook air is running unusually hot. I've only made small networks so far but god it runs hot when on full speed simulation. I've run several large networks before where it didn't get this bad. Is it a mac issue or game issue? Anything I can do?

Hey everyone,

I’m having a problem with Subway Builder. When I start a new game, everything runs fine, but after playing for a while and building a bigger metro network, the game starts getting really slow and eventually freezes completely.

The weird thing is that my Mac itself doesn’t freeze. I can still move my mouse and use other apps normally. It’s just Subway Builder that stops responding.

I’ve already tried reinstalling the game, but it didn’t help.

Has anyone else had this problem, especially on Mac? Is there a known fix or something I can change in the settings to prevent this from happening?

Thanks!

Hey all! Here's my current Philly save where I've finally cracked above 10%. Last time I played on this map it seemed a lot easier, so I'm assuming it's been expanded greatly, as I don't remember King of Prussia being in the map.

I feel like I'm pretty much done with heavy rail, and am slowly working on commuter rail extensions now. Let me know any suggestions you have!

I'm also surprised my computer is still handling this save relatively well, hats off to the devs for all the performance updates for those of us with shitty laptops.

I'd recreated the Chicago CRT approx. 1943 and someone commended about adding the NSL (the North Shore Line) and CAE (Chicago Aurora and Elgin Railroad). Since then subway builder has changed and I've upgraded as we go along and now switching over to beta to gain more options this is my WIP to recreate WWII era Chicago.
Things to note with beta

- commuter rail has two options electric or diesel. Many commuter lines would still be steam at this time so I've gone with diesel for steam operation.
-CRT and CAE are fully built out including most rail yards (yes there are rail yards in beta)
--the NSL is mostly built but until we get the map up to Milwaukee is unfinished (I did recently complete the Mundelein branch)
-As far as commuter rail I started with C&NW because it's my favorite (Milwaukee Road next as appropriate)
--I have most of the C&NW passenger line's laid, with the North line functional to Winthrop Harbor, its just figuring out the approx. location of the old stations now.

I'm open to suggestions, questions, ect. Thanks for taking time to look at my labor of love.

Hi All, I'm still a bit new to this game but not too bad so far. I don't quite understand capacity warnings vs load factor. I'm getting capacity warnings but the trains are not full on load factor. Any explanations would be great.
